DYNEXHigh Pressure HydraulicsENGINEERINGSPECIFICATIONSLow-Speed, High-TorqueVane MotorsHSM SERIESTorque to 13 750 lb•ft(18 645 N•m)HSM Series vane motors canincrease design flexibility, simplifyinstallation and reduce costs.Multiple speed models can improveefficiency.REDUCE WEIGHT AND SAVE SPACEThese motors transmit torque andmotion through a hollow, internalsplinerotor. This direct-drive designeliminates the need for costly gearreductions and simplifies installation.The motors can significantly reducethe space required on equipmentused in mining, construction, militaryand other mobile applications.Direct-drive is also well suited forindustrial applications, such as theinjector screw function on plasticmolding machines.SIMPLIFIED WIRING AND PIPINGThe thru-shaft spline drive simplifiessystem design and reduces installationtime. The large diameter shaftopening allows the use of either asolid or hollow output shaft.A hollow shaft accommodates theinstallation of wiring and other pipingthrough the center of the motor.This is an advantage on earth augersand drilling equipment and othersimilar applications. Air or water canbe pumped through the center of themotor to remove chips or debris fromthe drill hole.IDEAL FOR VERTICAL MOUNTINGThe thru-shaft rotor design makesthe motors ideal for machinesrequiring vertical shaft mounting.Models with optional vertical mountingcovers supply increased lubricationHSM200 Seriesbetween the rotor and runningsurfaces on the covers This providesincreased service life for theseapplications.For more information about thisvertical mounting option, contact theDynex sales department.REDUCED INPUT POWERMultiple displacement models areavailable which can reduce inputhorsepower requirements in circuitsusing fixed pumps.With two-speed models, the operatorcan efficiently select between twotorque/speed options. Three speedmodels provide minimum, medium ormaximum displacements.

Motors with hollow shafts providea passageway through the center of themotor for air, water, wiring, piping and othercontrol elements.

Efficient, Long-LifeMotor OperationEFFICIENT LONG-LIFE OPERATIONHSM motors deliver smooth rotarypower from stall to maximum speeds.A radially balanced design improvesmechanical efficiency and extendsoperating life.A unique square profile producesextra strength at the corners forextended fatigue life, especially athigh pressures.THERMAL SHOCK PROTECTIONOptional warm-up ports in HSMSeries motors can reduce thepotential for motor seizure caused bythermal shock.Thermal shock is caused by introducingwarmer fluid, from a workingportion of a circuit, into a coolermotor. A temperature differenceapproaching 50° F (10° C) can resultin uneven expansion of internal componentscausing motor seizure.Warm-up ports reduce the potentialfor shock by allowing fluid to becirculated through the motor withoutrotor rotation, equalizing fluid andmotor temperatures. This feature isespecially beneficial for mobileequipment used in cold weather.For information on this optioncontact your Dynex representative.HSM MOTORTAPBFLOW FROM ANAUXILIARY PUMPOR ANOTHERMACHINE CIRCUITWarm-up ports in the motor covers preventmotor seizure caused by thermal shock.RUNNING SURFACE SLOTSSlots carry fluid to and frommotor ports to cam “lobes”DOUBLE OUTLET COVEROptional multiple speed modelsreduce input horsepowerRADIALLY BALANCED DESIGNFor superior mechanical efficiencyand extended operating lifeUNIQUE “SQUARE” PROFILEExtra strength at corners extendsfatigue life at high pressuresCAM RINGRing contours form diametricallybalanced ramps, or “lobes”THRU-SHAFT ROTOR DESIGNPermits hollow shaft for simplifiedsystem design and installationHSM100 Series Multiple Displacement Motor2

Single and MultipleSpeed OperationHSM Series motors utilize a slottedrotor with 18 vanes that move radiallyagainst a cam ring. As the rotorturns, the vanes ride on the ring andslide in and out of the slots.The ring contours form four majorand four minor radial sections, joinedby transitional ramps, or lobes.Pressurized fluid is delivered to thelobes through slots in the coverrunning surface.MULTIPLE SPEED MODELSIn circuits using fixed displacementpumps, multiple speed/torquemodels can reduce input horsepowerrequirements.With two-speed models, the operatorcan select either full torque at normalspeed, or double speed at half thetorque. These models utilize a twoport cover, with each port independentlyconnected to a separate set ofdiametrically opposed lobes of equaldisplacement.Three-speed models offer greaterflexibility. The operator selects eitherminimum, medium or maximum displacement(with speed and torquedetermined by the specific model).These models also use a two-portcover, with a “split-rise” cam providingunequal displacements. In atypical circuit, shown below, aselector valve directs fluid to andfrom the motor ports to determinewhich pair of lobes will bepressurized.PRESSURE BALANCED VANESCAM RINGSingle-PortCover (C Port)HSM SERIES MOTORCATwo-PortCover (A & B Port)BFullDisplacementLOBESCam ring contours form diametricallybalanced ramps or “lobes”. This radiallybalanced design provides superiormechanical efficiency and extended life.MediumDisplacementMinimumDisplacementDISPLACEMENTSELECTORSINGLE SPEED MODELSIn single speed models, a port ineach motor cover connects to twosets of diametrically opposed and balancedlobes. Fluid entering the port inone cover causes the rotor to turn.Movement of the rotor transports fluidto the slots connected to the otherport, to return to tank. As the rotorturns, it drives the shaft which isspline connected to the rotor.The direction of rotation is determinedby which of the two ports arepressurized.ClockwiseRotationCounter-ClockwiseRotationDIRECTIONALVALVETypical three-speed motor circuit uses a displacement selector valve which directs fluid to andfrom the motor ports to determine the speed and torque combination. The direction of rotationis determined by the other directional valve in the circuit. This circuit is shown for referenceonly. Other circuit arrangements are possible and may be more beneficial depending on thespecific application.3
