High Pressure Hydraulics DYNEX ENGINEERING SPECIFICATIONS Low-Speed, High-Torque HSM SERIES Vane Motors Torque to 13 750 lb•ft (18 645 N•m) HSM Series vane motors can increase design flexibility, simplify installation and reduce costs. Multiple speed models can improve efficiency. REDUCE WEIGHT AND SAVE SPACE These motors transmit torque and motion through a hollow, internalspline rotor. This direct-drive design eliminates the need for costly gear reductions and simplifies installation. The motors can significantly reduce the space required on equipment used in mining, construction, military and other mobile applications. Direct-drive is also well suited for industrial applications, such as the injector screw function on plastic molding machines. SIMPLIFIED WIRING AND PIPING The thru-shaft spline drive simplifies system design and reduces installation time. The large diameter shaft opening allows the use of either a solid or hollow output shaft. A hollow shaft accommodates the installation of wiring and other piping through the center of the motor. This is an advantage on earth augers and drilling equipment and other similar applications. Air or water can be pumped through the center of the motor to remove chips or debris from the drill hole. IDEAL FOR VERTICAL MOUNTING The thru-shaft rotor design makes the motors ideal for machines requiring vertical shaft mounting. Models with optional vertical mounting covers supply increased lubrication between the rotor and running surfaces on the covers This provides increased service life for these applications. For more information about this vertical mounting option, contact the Dynex sales department. REDUCED INPUT POWER Multiple displacement models are available which can reduce input horsepower requirements in circuits using fixed pumps. With two-speed models, the operator can efficiently select between two torque/speed options. Three speed models provide minimum, medium or maximum displacements. For a complete description, see page 3. HSM100 Series Multiple Displacement Model HSM300 Series HSM200 Series MATERIAL PUMPED HSM WITH THRU-SHAFT ROTOR HOLLOW SHAFT Vertical mounting and a thru-shaft rotor design 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.
