HSM Series vane motors canincrease design flexibility, simplifyinstallation and reduce costs.Multiple speed models can improve efficiency. REDUCE WEIGHT AND SAVE SPACE These motors transmit torque andmotion through a hollow, internal- spline rotor. This direct-drive design eliminates the need for costly gear reductions 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 plastic molding machines. SIMPLIFIEDWIRINGANDPIPING The thru-shaft spline drive simplifiessystem design and reduces installa-tion time. The large diameter shaftopening allows the use of either a solid or hollow output shaft.A hollow shaft accommodates theinstallation of wiring and other piping through 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 from the drill hole.

HSM WITHTHRU-SHAFT ROTORHOLLOW SHAFT Multiple 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 speed models provide minimum, medium ormaximum displacements.For acomplete description, see page 3.
Vertical mounting and a thru-shaft rotordesign are advantages for earth augers and rock drills. Motors with hollow shafts provide a passageway through the center of the motor for air, water, wiring, piping and other control elements.
