  • FMC Series

    FMC series dual displacement hydraulic motor is an upgrade of the FMB series fixed displacement hydraulic motor.The FMC series dual displacement hydraulic motor enables users to select the required displacement for a wide range of special working conditions,meanwhile get high displacement and low displacement switching. 

Product features

  • With hydraulic balancing axial distribution technology,  the motor's operation has very high stability.

  • Axial flow distribution enjoys more powerful passing abilities.

  • The acting module of motor is designed with hydrostatic balance features,  which effects the motor with high transmission efficiency and outstanding start-up performance.

  • The rod surface friction pairs adopt abrasion-proof copper alloy, which provides better durability.

  • Patented design of ball head and ball socket structure, guarantees apporopriate hydraulic support force and superior heat dissipation performance.

  • The piston variable displacement mechanism, stable and reliable.


  • Range of application

    Can be widely used in shipbuilding, mining, construction metallurgy, petroleum, coal, geological drilling and other industries need different speed conditions.

Computational formula

①    The actual output torque of the hydraulic motor:M=0.159(P1-P2)V·ηm(N.m)

Where:P1、P2------------------------- Inlet and outlet pressure(MPa)

V--------------------------------- Displacement(ml/r)

ηm------------------------------- Mechanical efficiency(%)

②    Output power of the hydraulic motor:

N=(M·n)/9950(kW)N=[q(P1-P2)/60000]·ηm·ηv(kW)

Where:n-------------------------------- Rotation speed(r/min)

q-------------------------------- Input flow(ml/min)

ηv-------------------------------- Volumetric efficiency(%)

③    Rotating speed of the hydraulic motor:

n=q/V·ηv(r/min)
