A d v a nta ges o f M X P s e r i e s m o to r s ■■Definition of function Hydraulic motors transform hydraulic flow into rotating speed and hydraulic pressure into mechanical torque. Motor rotating speed is proportional to the flow which is supplied to it. Torque produced is proportional to the hydraulic pressure the motor receives. ■■Main applications of hydraulic motors Typical applications are those requiring high torque within a small size. The hydraulic motor is essential for rotations where: -- mechanical solutions are complex or even impossible, -- electrical or pneumatic power sources...

O pera ti n g co n d i ti o n s o f MX P se r ies m ot o r s ■■Hydraulic fluid ■■Rotating speeds LEDUC motors are designed to be powered with mineral based hydraulic fluid. Using other fluids is possible but may require a modified motor. Please contact us with details of fluid. Recommended viscosity: -- Ideally : between 15 and 200 cSt; -- Maximum range: between 5 and 1600 cSt. Minimum rotating speed to obtain continuous rotation is 200 rpm (however, in certain conditions, the motor can run at speeds as low as 50 rpm). Maximum rotating speed is given for each model of motor (see page 4). ■■Filtration...

De te rmi na t ion MX P se r ies m ot o r s ■■How to determine the correct motor for your application Calculations using usual mechanical units: N = rotating speed in rpm C = torque in N.m P = pressure supplied by the generator (hydraulic pump), in bar ΔP = pressure difference between A and B, in bar Disp. = displacement in cc Q = flow in litres per minute η = efficiency (%) 1. Torque supplied by the hydraulic motore Torque C = Cth x ηmotor For example: a 50cc motor with a ∆P of 250 bar will supply a theoretical torque of : 200 N.m. Average global efficiency of the motor is 90%, actual torque...
