MotorsIndustrial ProductsCircuit and Application NotesStarting TorqueThe starting torques shown on the graphs on pages 9 to 12 are average and will vary with systemparameters.Low Speed OperationsMinimum operating speeds are determined by the hydraulic system and load conditions (load inertia, driveelasticity, etc.) Recommended minimum speeds are shown below:Model Typer/minB010 20B030 5B045 6B06080/100/125/150/200 3B270/B325/HMB400 2B700 1Note: Speed as low as 0.025 rpm can be accurately achieved using electronic control systems. Foroperation at speeds below these figures please contact Kawasaki Precision Machinery (UK) Ltd.High Back PressureWhen both inlet and outlet ports are pressurised continuously, the lower port pressure must not exceed 70bar at any time.Note: High back pressure reduces the effective torque output of the motor.Boost PressureWhen operating as a motor the outlet pressure should equal or exceed the crankcase pressure . If pumpingoccurs (i.e. overrunning loads) then a positive pressure ,”P” ,is required at the motor ports .Calculate “P”(bar) from the operating formulaBoost Formula P= 1+ N 2 x V 2 + CKWhere P is in Bar, N = motor speed (RPM), V = motor displacement (cc/rev.), C=Crankcase pressure(BAR) and K=a constant from the table below:MOTOR PORTING CONSTANTHMB010 Standard 8 x 10 8HMB030Standard 3.7 x 10 9SO3, F(M)3 7.5 X 10 9HMB045HMB060/080/100Standard 1.3 x 10 10SO3, F(M)3 1.6 X 10 10F(M)2 2.7 x 10 9F(M)3, S03 1.8 X 10 10F(M)2 4.2 X 10 9HM(HD)B125/150/200 F(M)3, S03 4.0 X 10 10F(M)4, S04 8.0 X 10 10HM(HD)B270/325 F(M)4, S04 7.2 X 10 10HMHDB400Standard 6.0 X 10 10S045 7.2 X 10 10HMB700 Standard 1.3 x 10 11ModelStaffaPage26.70Data SheetM-1001/03.00Issue 03/00
Industrial ProductsMotorsCircuit and Application Notes (continued)The flow rate of oil needed for the make-up system can be estimated from the crankcase leakage figure(see Volumetric Efficiency graphs pages 19 to 29) Allowances should be made for other system losses andalso for “fair wear and tear” during the life of the motor, pump and system components.Cooling FlowOperating within the continuous rating does not require any additional cooling.For operating conditions above “continuous”, up to the “intermittent” rating, additional cooling oil may berequired.This can be introduced through the spare crankcase drain holes, or in special cases through the valvespool end cap. Consult Kawasaki about such applications.Motor Casing PressureWith the standard shaft seal fitted, the motor casing pressure should not exceed 3.5 bar.Notes:1. The casing pressure at all times must not exceed either the motor inlet or outlet pressure.2. High pressure shaft seals are available for casing pressures of:6 Bar for HMB7009 Bar for HMB 01010 Bar for all remaining frame sizes.3. Check installation dimensions for maximum crankcase drain fitting depth.Hydraulic FluidsDependent on motor (see Ordering Code.) suitable fluids include:(a) Antiwear hydraulic oils.(b) Phosphate ester (HFD fluids )(c) Water glycols ( HFC fluids)(d) 60/40% water-in-oil emulsions ( HFB fluids).(e) 5/95% oil-in-water emulsions (HFA fluids)Reduce pressure and speed limits, see page 6.Viscosity limits when using any fluid except oil-in-water (5/95) emulsions are;Max. off load 2000cSt (9270 SUS)Max. on load 150 cSt (695 SUS)Optimum50 cSt (232 SUS)Minimum25cSt (119 SUS)ModelStaffaPage27.70Data SheetM-1001/03.00Issue 03/00
