Planet Products Corporation, Dayton Lamina and Bosch Rexroth are among the manufacturers of high-speed hydraulic motors. Used in a variety of applications including submarine controls and machine cutter tools, Planet Products' heavy duty motors range in speed from 3,000 to 4,000 revolutions per minute. Lamina's hydraulic motors produce four-times greater torque at one-fourth the conventional speed, according to the company. Rexroth's high-speed hydraulic motors include axial piston, fixed or variable, displacement motors, external gear and radial piston motors.
Geartex and Hydro Leduc also manufacture high-speed hydraulic motors. Geartex's C45 hydraulic motor has a maximum speed of 3,600 revolutions per minute. Hydro Leduc motors offer a choice of increased bearing capacity and feature a seven-piston design and high pressure oil injection piston heads to reduce friction, heat and wear. The Hydro LeDuc MXP motor has options of intermittent and continuous speeds up to 8,800 revolutions per minute.
High-speed hydraulic motors convert hydraulic pressure into force at a rapid rate, thereby generating a large amount of power quickly and efficiently. The effectiveness of a high-speed hydraulic motor depends not only on the speed, but on control of the speed and torque in relation to the process in order to ensure efficiency and quality. Accordingly, most manufacturers offer some level of customization.
