Standard Construction of Sleeve Bearing

The sleeve bearings are the flange-mounted type in accordance with DIN 31693. 4 pole AMCs have center flange-mounted bearings acc. to DIN 31694 . 50 Hz machines have cylindrical sleeve shells, 60 Hz machines have 4 lobe sleeve shells.

The bearing housing is manufactured in high grade cast iron and is designed for heavy duty performance. The bearing shells are spherically seated in the housing.

The housing, seals and oil-ring are all in split design. This enables the bearing shells and seals to be dismantled without uncoupling the machine. Both bearings have the same diameter. AMC 4 pole with 4 lobe sleeve shells are without oilring! Note: No emergency oil function on these bearings.

On the standard design, both bearings are non-locating (Bearing end float +/- 6.5 mm). It is assumed that axial guidance of the shaft train is provided by the driven equipment or gearbox.

(Locating bearing see options.)

The lubrication intervals for a bearing operation temperature of 70C and lithium soap base grease are given in the next two tables. The grease nipples are brought out from the bearing to an accessible point on the machine via a tube.

On the D-end bearing, excess and used grease is expelled by a grease valve through an opening on the lower part of the bearing cover into a container.

On the N-end bearings, the excess and used grease is expelled, into a used grease container lecated on the top part of the endshield outside of the machine. The used grease container is oversized to contain more than the total quantity of grease required for greasing during the whole bearing life.

$7 "%The insulation materials employed meet the requirements for Class F as defined by IEC (maximum permissible temperature 155C).The stator coils are wound from rectangular shaped wire. The insulation structure is the Micadur-Compact system, now well established for almost thirty years, and by which the coils are wrapped over their whole length with overlapped layers of glass-mica tape (refer also to brochure 3BFP 001 980 R0101 REV A 12/98 Micadur-Compact Industry Insulation System for Rotating Electrical Machines). The winding slots are closed with highly permeable, powder composition wedges.

Irrespective of voltage, the finished wound stator is subjected to vacuum-pressure-impregnation and cured in a hot air oven. The winding elements are then so rigid that they can withstand the forces arising during system transfers and short-circuits without sustaining damage.

In addition to the final high-voltage test performed on the finished machine, dielectric tests with a.c. voltage and impulse voltage with steep wave fronts are carried out during winding production to ensure that the coil and turn to turn insulation meet the specified requirements (surge withstand impulse strength in accordance with IEC 60034 - 15).Remark: Experience made by many users and manufacturers has shown that occasionally surge voltages can arise which subject the motors to more severe conditions than those specified by IEC 60034-15. For rated voltages above 11 kV, overvoltage protection, consisting of surge capacitors and ZnO voltage arresters, is provided close to the motor terminals. The purpose would be to provide a reliable protection of the motors against switching surges with steep wave fronts and high amplitudes, which can arise particularly with vacuum breakers at pre-ignition and multiple restriking.

The standard design includes 6 resistance temperature detectors, 3 or 4-wire type Pt100, in the winding slots to monitor the stator winding temperature (2 per phase). The leads are led to the auxiliary terminal box.

($

Second vacuum impregnation for nuclear plants, extended exposure to steam, or extremely dirty operating areas

$7 .%The standard design incorporates a copper, deep-bar cage winding. The bars are hard-soldered to the short-circuit rings by a long established and well proven technique. The bars are swaged along their whole length to afford a tight fit to the slot walls. This prevents damaging bar vibration. A reinforced high-strength shrink rings is needed for some motors with high circumference speed.

The terminal box is a welded construction and is flange-mounted to the machine housing. The degree of protection is IP55. A pressure relief flap is provided in the back wall, which would open towards the machine in case of a short-circuit in the terminal box. The standard design is for plastic insulated cables entering from below. It can be turned in steps of 90 in either direction to afford cable entrance from the side or from above. The direction of cable entrance should be known when placing the order because changes after manufacture are not always possible.

The standard design includes a blank gland plate in order to accommodate the numerous connection possibilities open. The table below shows the preferred number of cables entering the terminal box for the different types of terminals.

Switching operations, as for instance reswitching following short voltage interruptions, can produce torques inadmissible for the standard machines. If such are expected, a torsional vibrational analysis should be performed. Should the motor manufacturer be contracted to carry out these calculations he must be furnished with the necessary data on the shaft train components and on the conditions of the power supply system.

7 ++2Converter-fed operation leads to a reduction in the nominal output because of additional losses resulting from non-sinusoidal voltages and currents. Furthermore, oscillating torques arise and are superimposed to the constant driving torque. Should the exciting and resonant frequencies coincide, these torques could lead to inadmissible stressing in the shaft train. Therefore, it is a basic principle that for converter-fed operation a torsional vibration analysis must be performed in order to check the mechanical stresses in the whole shaft train. The motor manufacturer is not responsible for torsional analysis.

$The integrated Sinus-filter reduces the effects of the converter to a negligible extent.

!7 5Due to the voltage harmonics which arise during converter-fed operation the winding insulation is laid out for at least double the rated motor voltage.

For with sinusoidal filter normal insulation for line fed machines can be applied.

For machines fed by a non-ABB converter, special information on insulation requirements have to be provided.

!7

Converter-fed operation causes additional shaft voltages which could result in bearing damage.

Depending on the converter type the following provisions are recommended:

ACS 1000: no special provision necessary

ACS 6000 and Megastar: Independent of bearing type (antifriction, sleeve) both bearings has to be insulated

ACS 600: Independent of bearing type both bearings have to be insulated

other converters on request

Additionally careful grounding of the motor, right choice of the feeding cable and its correct protective earthing contribute to a failure free operation of the motor.

In case of motors fed by ACS 600 a common mode filter should be provided.

To prevent bearing current paths, also the speed monitor has to be fully insulated against the shaft.

!7 "As a rule, speed monitoring is necessary for machine control. Therefore, the N-end of the shaft provides the possibility of mounting a speed monitor. The associated extra charge, including that for the recommended speed monitors are to be extracted from the accessories price list.

Self-ventilation is sufficient for driven equipment with a load characteristic where the torque varies to the square of the speed (e.g. pumps). If the torque is independent or only slightly 3BSM900026, en 15-74

dependent on the speed, then self-ventilation is not sufficient to provide for an effective heat transfer in the lower speed range. In such cases, the necessary air circulation must be provided by separate ventilation. In air-air cooled machines this is true for both the primary and secondary cooling circuit.

!7! *

Current harmonics cause additional noise excitation. In general, the noise level is therefore higher for converter-fed operation than for line operation. For machines which already have a high noise level (high speed and air-air cooler) in direct online operation, the difference will generally be about 6 dB(A). For machines with a relatively low noise level (e.g. air-water cooler and low to medium speed), the difference can be up to 10 dB(A). Binding data should be requested for each particular case.

Exception: For ACS 1000 the noise increase will only be 1,5 dB (A).

When selecting the machine it must be ensured that the first critical speed is at least 20% above the operating speed range. In case of machines having an operating speed range between two critical speeds, the critical speeds must have at least 20% margin to the specified speed range.
