Key Points of Selection:

It must be chear that the service factor f_B(See the table below), output speed and motor power when selecting MRD drive RK series helical geared motor. The service factor f_B shows the application and working condition for the working machine. If you want the gears of the speed reducer be durable, the actual service factor of the working machine f_BL should lower than f_B,that is f_BL < f_B.f_B: The maxium service factor of the geared motor
f_BL: Actual service factor of the working machine
