2 General notes on the product description Product Description
2 Product Description 2.1 General notes on the product description Ambient tempera- ture
Gear units and gearmotors from SEW-EURODRIVE can be operated in a wide ambient temperature range. The following standard temperature ranges are permitted for filling the gear units according to the lubricant table:
The rated data of the gear units and gearmotors specified in the catalog/price catalog refer to an ambient temperature of +25 °C. Gear units and gearmotors from SEW-EURODRIVE can be operated outside the stan- dard temperature range if project planning is adapted to ambient temperatures from as low as up to -40 °C in the intensive cooling range until up to +60 °C. Project planning must take special operating conditions into account and adapt the drive to the ambient conditions by selecting suitable lubricants and seals. This kind of project planning is gen- erally recommended for increased ambient temperatures as of size 97 and for helical- worm gear units with small gear ratios. SEW-EURODRIVE will gladly perform this proj- ect planning for you.
If the drive is to be operated on a frequency inverter, you must also consider the project planning notes of the inverter and take into account the thermal effects of inverter oper- ation.
Installation altitude
Due to the low air density at high installation altitudes, heat dissipation on the surface of motors and gear units decreases. The rated data listed in the catalog/price catalog ap- plies to an installation altitude of maximum 1000 m above sea level. Installation altitudes of more than 1000 m asl must be taken into account for project planning of gear units and gearmotors.
Power and torque The power and torque ratings listed in the catalogs refer to mounting position M1 and similar mounting positions in which the input stage is not completely submerged in oil. In addition, the gearmotors are assumed to be standard versions with standard lubrica- tion and under normal ambient conditions. Please note that the motor power shown in the selection tables for gearmotors is subject to selection. However, the output torque and the desired output speed are essential for the application and need to be checked.
Speeds The quoted output speeds of the gearmotors are recommended values. You can calcu- late the rated output speed based on the rated motor speed and the gear unit ratio. Please note that the actual output speed depends on the motor load and the supply sys- tem conditions.
Noise The noise levels of all SEW-EURODRIVE gear units, motors and gearmotors are well within the maximum permitted noise levels set forth in the VDI guideline 2159 for gear units and IEC/EN 60034 for motors.
Gear unit Filled with Permitted standard temperature range
Helical, parallel-shaft helical and helical-bevel gear units CLP(CC) VG220 -10 °C ... +40 °C

Coating Gear units, motors and gearmotors from SEW-EURODRIVE are painted with "SEW blue" as standard. Special paints are available on request. Exception: Spiroplan® W..10 DT56 gearmotors have an aluminum housing and are supplied unpainted as standard.
Surface and corrosion protection
If required, all gear units, motors and gearmotors from SEW-EURODRIVE can also be supplied with special surface protection for applications in extremely humid and chemi- cally aggressive environments.
Weights Please note that all weights shown in the catalogs exclude the oil fill for the gear units and gearmotors. The weights vary according to gear unit type and gear unit size. The lubricant fill depends on the mounting position which means no universally applicable information can be given. Please refer to "Lubricants" in the "Design and Operating Notes" section for recommended lubricant fill quantities depending on the mounting po- sition. For the exact weight, refer to the order confirmation.
Air admission and accessibility
The gearmotors/brakemotors must be mounted on the driven machine in such a way that both axially and radially there is enough space left for unimpeded air flow, for main- tenance work on the brake and, if required, for the MOVIMOT® inverter. Please also re- fer to the notes on the motor dimension sheets in the AC Motor Catalog.
Multi-stage gear units
You can achieve particularly low output speeds by using multi-stage gear units or multi- stage gearmotors. Such a setup requires a helical gear unit or gearmotor on the input end as a second gear unit. It may be necessary to limit the motor power to match the maximum permitted output torque of the gear unit.
Reduced back- lash gear units
Helical, parallel-shaft helical and helical-bevel gear units with reduced backlash are available from gear unit size 37 and up. The circumferential backlash of these gear units is considerably less than that of the standard versions so that positioning tasks can be solved with great precision. The circumferential backlash is specified in angular minutes [’] in the technical data. The circumferential backlash for the output shaft is specified without load (max. 1% of the rated output torque); the gear unit input end is blocked. For further information, refer to section "Reduced backlash gear units" on page 94.
NOCO® Fluid paste for protection against contact corrosion
As standard, all shaft-mounted gear units and gearmotors are supplied with NOCO®
Fluid, a paste that prevents contact corrosion. Use this paste in accordance with the in- structions in the gear unit operating instructions. It facilitates service and stripping down jobs. NOCO® fluid is a food grade substance according to NSF-H1. You can tell that NOCO®
Fluid is a food grade oil by the NSF-H1 identification label on its packaging.
RM gear units, RM gearmotors
RM gear units and RM gearmotors are a special type of helical gear units with an ex- tended output bearing hub. They were designed especially for agitating applications can be used in applications subject to high overhung and axial loads. The remaining data correspond to the standard helical gear units and helical gearmotors. You can find spe- cial project planning notes for RM gearmotors in the "Project Planning for Gear Units/RM gear units" section.
12 Catalog – DRE-GM 01/2010
Spiroplan® right- angle gearmotors
Spiroplan® right-angle gearmotors are robust, single- and two-stage right-angle gear- motors with Spiroplan® gearing. The difference to the helical-worm gear units is the ma- terial combination of the steel-on-steel gearing, the special tooth meshing relationships and the aluminum housing. As a result, Spiroplan® right-angle gearmotors are wear- free, very quiet and light. The particularly short design and the aluminum housing make for very compact and lightweight drive solutions. After the running-in period, some sizes of the Spiroplan® right-angle gearmotor series are below the following sound pressure level in 4-pole motor operation on a 50 Hz sup- ply system: • Spiroplan® W..10 to W..30: 55 dB(A) The sound-pressure level may be 3 to 5 dB(A) higher at time of delivery than after hours of regular operation. The wear-free gearing and the life-long lubrication facilitate long periods of mainte- nance-free operation. The oil filling being independent of the mounting position, except for Spiroplan® W..37 and W..47 in mounting position M4 makes any position possible for Spiroplan® right-angle gearmotors without altering the quantity of oil. Identical hole spacing in the foot and face, as well as the equal shaft height to both, provides you with diverse mounting options. Two different flange diameters are available. On request, Spiroplan® right-angle gear- motors can be equipped with a torque arm.
Brakemotors On request, motors and gearmotors can be supplied with an integrated mechanical brake. The SEW-EURODRIVE brake is an electromagnetic disk brake with a DC coil that releases electrically and brakes using spring force. Due to its operating principle, the brake is applied if the power fails. It meets the basic safety requirements. The brake can also be released mechanically if equipped with manual brake release. For this pur- pose, the brake is supplied with either a hand lever with automatic reset or an adjustable setscrew. The brake is controlled by a brake controller that is either installed in the motor wiring space or the control cabinet. A characteristic feature of the brakes is their very short design. The brake bearing end shield is an integral part of both the motor and the brake. The integrated construction of the SEW-EURODRIVE brakemotor permits particularly compact and sturdy solutions.

2 General notes on the product description Product Description
2 Product Description 2.1 General notes on the product description Ambient tempera- ture
Gear units and gearmotors from SEW-EURODRIVE can be operated in a wide ambient temperature range. The following standard temperature ranges are permitted for filling the gear units according to the lubricant table:
The rated data of the gear units and gearmotors specified in the catalog/price catalog refer to an ambient temperature of +25 °C. Gear units and gearmotors from SEW-EURODRIVE can be operated outside the stan- dard temperature range if project planning is adapted to ambient temperatures from as low as up to -40 °C in the intensive cooling range until up to +60 °C. Project planning must take special operating conditions into account and adapt the drive to the ambient conditions by selecting suitable lubricants and seals. This kind of project planning is gen- erally recommended for increased ambient temperatures as of size 97 and for helical- worm gear units with small gear ratios. SEW-EURODRIVE will gladly perform this proj- ect planning for you.
If the drive is to be operated on a frequency inverter, you must also consider the project planning notes of the inverter and take into account the thermal effects of inverter oper- ation.
Installation altitude
Due to the low air density at high installation altitudes, heat dissipation on the surface of motors and gear units decreases. The rated data listed in the catalog/price catalog ap- plies to an installation altitude of maximum 1000 m above sea level. Installation altitudes of more than 1000 m asl must be taken into account for project planning of gear units and gearmotors.
Power and torque The power and torque ratings listed in the catalogs refer to mounting position M1 and similar mounting positions in which the input stage is not completely submerged in oil. In addition, the gearmotors are assumed to be standard versions with standard lubrica- tion and under normal ambient conditions. Please note that the motor power shown in the selection tables for gearmotors is subject to selection. However, the output torque and the desired output speed are essential for the application and need to be checked.
Speeds The quoted output speeds of the gearmotors are recommended values. You can calcu- late the rated output speed based on the rated motor speed and the gear unit ratio. Please note that the actual output speed depends on the motor load and the supply sys- tem conditions.
Noise The noise levels of all SEW-EURODRIVE gear units, motors and gearmotors are well within the maximum permitted noise levels set forth in the VDI guideline 2159 for gear units and IEC/EN 60034 for motors.

Coating Gear units, motors and gearmotors from SEW-EURODRIVE are painted with "SEW blue" as standard. Special paints are available on request. Exception: Spiroplan® W..10 DT56 gearmotors have an aluminum housing and are supplied unpainted as standard.
Surface and corrosion protection
If required, all gear units, motors and gearmotors from SEW-EURODRIVE can also be supplied with special surface protection for applications in extremely humid and chemi- cally aggressive environments.
Weights Please note that all weights shown in the catalogs exclude the oil fill for the gear units and gearmotors. The weights vary according to gear unit type and gear unit size. The lubricant fill depends on the mounting position which means no universally applicable information can be given. Please refer to "Lubricants" in the "Design and Operating Notes" section for recommended lubricant fill quantities depending on the mounting po- sition. For the exact weight, refer to the order confirmation.
Air admission and accessibility
The gearmotors/brakemotors must be mounted on the driven machine in such a way that both axially and radially there is enough space left for unimpeded air flow, for main- tenance work on the brake and, if required, for the MOVIMOT® inverter. Please also re- fer to the notes on the motor dimension sheets in the AC Motor Catalog.
Multi-stage gear units
You can achieve particularly low output speeds by using multi-stage gear units or multi- stage gearmotors. Such a setup requires a helical gear unit or gearmotor on the input end as a second gear unit. It may be necessary to limit the motor power to match the maximum permitted output torque of the gear unit.
Reduced back- lash gear units
Helical, parallel-shaft helical and helical-bevel gear units with reduced backlash are available from gear unit size 37 and up. The circumferential backlash of these gear units is considerably less than that of the standard versions so that positioning tasks can be solved with great precision. The circumferential backlash is specified in angular minutes [’] in the technical data. The circumferential backlash for the output shaft is specified without load (max. 1% of the rated output torque); the gear unit input end is blocked. For further information, refer to section "Reduced backlash gear units" on page 94.
NOCO® Fluid paste for protection against contact corrosion
As standard, all shaft-mounted gear units and gearmotors are supplied with NOCO®
Fluid, a paste that prevents contact corrosion. Use this paste in accordance with the in- structions in the gear unit operating instructions. It facilitates service and stripping down jobs. NOCO® fluid is a food grade substance according to NSF-H1. You can tell that NOCO®
Fluid is a food grade oil by the NSF-H1 identification label on its packaging.
RM gear units, RM gearmotors
RM gear units and RM gearmotors are a special type of helical gear units with an ex- tended output bearing hub. They were designed especially for agitating applications can be used in applications subject to high overhung and axial loads. The remaining data correspond to the standard helical gear units and helical gearmotors. You can find spe- cial project planning notes for RM gearmotors in the "Project Planning for Gear Units/RM gear units" section.

Spiroplan® right- angle gearmotors
Spiroplan® right-angle gearmotors are robust, single- and two-stage right-angle gear- motors with Spiroplan® gearing. The difference to the helical-worm gear units is the ma- terial combination of the steel-on-steel gearing, the special tooth meshing relationships and the aluminum housing. As a result, Spiroplan® right-angle gearmotors are wear- free, very quiet and light. The particularly short design and the aluminum housing make for very compact and lightweight drive solutions. After the running-in period, some sizes of the Spiroplan® right-angle gearmotor series are below the following sound pressure level in 4-pole motor operation on a 50 Hz sup- ply system: • Spiroplan® W..10 to W..30: 55 dB(A) The sound-pressure level may be 3 to 5 dB(A) higher at time of delivery than after hours of regular operation. The wear-free gearing and the life-long lubrication facilitate long periods of mainte- nance-free operation. The oil filling being independent of the mounting position, except for Spiroplan® W..37 and W..47 in mounting position M4 makes any position possible for Spiroplan® right-angle gearmotors without altering the quantity of oil. Identical hole spacing in the foot and face, as well as the equal shaft height to both, provides you with diverse mounting options. Two different flange diameters are available. On request, Spiroplan® right-angle gear- motors can be equipped with a torque arm.
Brakemotors On request, motors and gearmotors can be supplied with an integrated mechanical brake. The SEW-EURODRIVE brake is an electromagnetic disk brake with a DC coil that releases electrically and brakes using spring force. Due to its operating principle, the brake is applied if the power fails. It meets the basic safety requirements. The brake can also be released mechanically if equipped with manual brake release. For this pur- pose, the brake is supplied with either a hand lever with automatic reset or an adjustable setscrew. The brake is controlled by a brake controller that is either installed in the motor wiring space or the control cabinet. A characteristic feature of the brakes is their very short design. The brake bearing end shield is an integral part of both the motor and the brake. The integrated construction of the SEW-EURODRIVE brakemotor permits particularly compact and sturdy solutions.
