Precautions for Selecting DOWMAX Motors
Attention should be paid to the following matters when selectingDOWMAX motors. Carefully read precautions shown in the cata-logue and instruction manual to thoroughly understand thembefore selecting motors.
Check that the hydraulic system is planned in a manner to satisfythe matters described in the catalogue, instruction manual, deliv-ery drawing, manufacturing specifications, etc. Pay special atten-tion to the following:
1)The performance curves shown is this catalogue show the sum-mary (average values) of data on motors that have already beenrun-in. Provide sufficient margin of safety when selecting motorsin accordance with specific applications. When motors are mew (before running-in), they may fail to achievethe performance shown in the catalogue. Contact us if that willcause any problem.
2) In cases where high back pressure is applied to the outlet line ofthe motor in special application, the performance described in thecatalogue may not be exhibited. Contact us if the back pressureapplied to the outlet line of the motor exceeds 2.0MPa (20kgf/cm2).
3) In cases where the motor is turned by a load, it is necessary toapply boost pressure to the suction line of the motor to preventcavitation. The boost pressure is subject to the motor speed andthe viscosity of hydraulic fluid. In general, apply pressure thatexceeds the minimum, boost pressure shown for each model.
4) In cases where external load torque is applied to the motor shaftwhile the motor is at rest, the motor will turn (slip) due to theleakage inside the motor. If there is no supply circuit, cavitationoccurs and the motor goes out of control. (For example, a loadwill drop suddenly.) Use a mechanical brake, as necessary inthese cases.
5) In cases where the inertial force of a driving body is large, abnor-mal pressure will be produced. Measure the pressure of the actualmotor, and use a brake valve if the peak pressure exceeds thevalue shown in the catalogue; otherwise the motor shaft, key, andother parts may be damaged. Plan pipe installation in a manner tosatisfy matters described in the related instruction manual.
Precautions for mechanical brake.
1)Mechanical brake of DOWMAX motor is reverse-operation type, thebrake is released when brake pilot line is pressurized.
a. Pay attention, when planning hydraulic circuit, to the brake pilot line not being pressurized at any time the brake is necessary,even if it's an instant time.
b. When residual pressure remains at the brake pilot line, brake torque decreases proportional to the residual pressure.Brake torque shown in this catalogue is for the brake pilot linepressure of 0kgf/cm2.
2)Mechanical brake of DOWMAX motor is originally for a static brakeuse (parking brake).Avoid the use of dynamic brake to the utmost.When dynamic brake is used unavoidably, pay attention to the fol-lowings:
a. Mechanical brake and hydraulic brake shall not be usedtogether.When mechanical and hydraulic brake are planned to be usedtogether, consult us for the applicability.
b. Usage classified as "Unsafe range" in the "Brake Use LimitJudging Diagram" in the related Instruction Manual, shall beavoided.
c. When the brake is used as a dynamic brake, the brake friction plate will be worn.Check the brake torque periodically, and replace the brake fric-tion plates with new ones, if necessary.
3)Brake torque shown in this catalogue is for the use of standardmineral oil as a hydraulic fluid.When other oils such as fire-resistant fluid or special oils containsadditive are used, brake characteristics will differ from the value inthe catalogue, consult us in the case.
Do not plan operation exceeding the usable conditions describedin this catalogue. (This does not apply to motors made to specialspecifications if special mention is shown in the delivery drawingor product specifications.)
1)Operation exceeding the viscosity range of 15-500 cSt.
2) Operation exceeding the usable range (pressure and speed).Refer to this catalogue for confirmation of limits for respectivemodels.
3) Operation exceeding the allowable external force (radial andthrust load). Refer to the shaft strength diagrams shown in thiscatalogue for confirmation.
4) Operation exceeding the operating conditions (pressure andspeed) corresponding to the desired life of motor.Check the bearing life diagrams shown in this catalogue for con-firmation.
5)Operation in cold places (below -25)(Contact us for special motors for operation at temperatures from-25 to -45.)
6)Operation that causes the case temperature to exceed 80.
Never remodel motors.
Precautions for Selecting DOWMAX Motors
Use the recommended hydraulic fluid shown in instruction manu-al. When fire-resistant fluid is used, strictly observe the cautionsand notes described in the instruction manual. Standard motorscannot be used when phosphate-ester is used as hydraulic fluid.In that case, select the seal code of V or X (seal material: fluo-rorubber). As in the case of water-glycol type hydraulic fluid, themotor life can substantially be shortened depending on the typeof fire-resistant fluid.(Contact us for the expected life of motor under specific operat-ing condition.)
When the direction of rotation of the motor is to be changed fre-quently, select models with a spline shaft.
Metal chips, sand, and other fine foreign substances contained inhydraulic fluid will reach the sliding surface of the motor, advanc-ing the abrasion of component parts and causing malfunction andseizure of the motor. Prevent entry of dust, and be sure to installa filter in the circuit. Refer to the related instruction manual for thefilter specifications.
Precautions regarding the drain port position and drain piping aredescribed in the related instruction manual. Be sure to refer tothem and reflect them in the piping plan.
When installation of motor with its shaft facing upward is desired,select "DOWMAX for installing the shaft upward" (mentionedbefore) that permits air bleeding from the case.
Keep the drain pressure inside the motor case below 0.3MPa (3kgf/cm2). Take care the pressure as it rises depending on the tankposition and the length and diameter of pipes. The pressure onthe low-pressure side of the main port must be higher than thedrain pressure.
When the shaft is exposed to water or seawater, the standard sealwill allow the shaft to rust, and the abraded oil seal may cause oilleakage. In such a case, select or specify models made to thedouble oil seal specifications.

Fluid entering the supply port is directed via internal passages and timing plate to the center of the cylinder bores.
Fluid pressure forces the pistons apart causing the slippers to slide on the angled faces of the swash plates and rotate
the barrel and shaft assembly. After work, fluid is exhausted through the timing plate and internal passages to the
return port.

3. The graphs shown are the bearing life (B-10 Life) at 100 rpm shaft speed (500 rpm only for ME100)for various pressures and radial loads.When the shaft speed differs from 100 rpm (500 rpm only for ME100) the bearing life can beobtained by the following formula:
(Bearing Life obtainable in 100 (500 for ME100)B-10 Life the graph) Actual Shaft Speed, rpm
In case where the side load acts at a different location to the midpoint of the shaft projection pleaserefer to us.
4. Applications with axial thrust loads should be referred to us.5. When motor is used in Meter-Out circuit, pressure in Fig. 2 & 3 shaft be asum of motor inlet and outlet pressure.
6. Bearing life varies due to kind of fluid.Bearing life should be decided bymultiplying by the factor below:

In order to maintain the maximum bearing life, when a radial load is imposed on the outputshaft the motor should be installed as illustrated in Fig. 2 or Fig. 3;For a uni-directional application, motor should be installed so that side load acts asshown in Fig. 2.For a bi-directional application, a radial load for each rotational direction being applied,the motor should be installed so that side loads act as shown in Fig. 3.

3. The graphs shown are the bearing life (B-10 Life) at 100 rpm shaft speed (500 rpm only for ME100)for various pressures and radial loads.When the shaft speed differs from 100 rpm (500 rpm only for ME100) the bearing life can beobtained by the following formula:
(Bearing Life obtainable in 100 (500 for ME100)B-10 Life the graph) Actual Shaft Speed, rpm
In case where the side load acts at a different location to the midpoint of the shaft projection pleaserefer to us.
4. Applications with axial thrust loads should be referred to us.5. When motor is used in Meter-Out circuit, pressure in Fig. 2 & 3 shaft be asum of motor inlet and outlet pressure.
6. Bearing life varies due to kind of fluid.Bearing life should be decided bymultiplying by the factor below:
Fluid typeMineral-based fluidPhosphate-ester fluidWater-glycol w/o forced lubricationWater-glycol w/ forced lubrication
life factor1.01.0
