YMP Series Hydraulic Motor for OEM Applications-Image

YMP Quick Reference Guide

The YMP series motors use the spool valve shaft distribution design for simplicity and efficiency. This design integrates the distribution and hydraulic bearing design with the motor shaft.

This motor series uses the "ROTOR" gear type manufactured with most advanced technology and quality available to provide high torque and low speed. The gear set of the "rotor" multiplies the output torque without the need of gear reducers that could be required in many applications.

These motors are very compact, economical, powerful, effi cient and are designed for medium duty applications.

The large number of displacements, mounting fl anges, shafts, valving and other options available for these motors makes them a very fl exible unit for many applications.

Distribution Type: Spool Valve Distribution
Model: YMP
Displacement: [in/rev] [2.18~24.41] cm/rev 36~400
Max Operating Pressure: PSI = 2400 MPa = 16.5
Speed Range: RPM = 30~879
Max. Output Power: [HP] [27] Kw = 10

Shaft Seals: Standard high pressure shaft seals permit applications in series or without
drain line when required
Low Speed Valving: These motors are manufactured following strict procedures to reduce tolerances between all components to permit lower speed, higher efficiency and smoother rotation at very low speeds. These motors are not for high speed or low pressure applications.
Free Wheeling: These motors are created for applications where free wheeling is required
or could be benefi cial to the best results of the application and life of the motors and other components.
Special Motors: These motors have special options like nickel plated shafts or housings for
corrosive environments and applications.

APPLICATION GUIDELINES:
For optimum results the following working conditions are recommended:
* Oil temperature should be between 20o - 60o C [68o - 180o F]
* Oil filter of 10 - 20 micron
* Oil viscosity 42 - 74 mm2 at 40o C
* Different shafts are used when there is a radial load or not. Check data pages
* For longer life we suggest the motor at start up, run for a shorter period of time (one hour) at
no more than 30% of rated speed and pressure.
