Selection of a geared motor
This choice is based upon the desired usable power at the gearbox output shaft
2
π
Power = ------ C n
60
(W)
(Nm) (Rpm)
A geared motor must have usable power equal to or greater than the power required to rotate the load
desired. It is selected by checking that the point corresponding to the required operating conditions
(torque and speed output) is higher than the nominal torque versus speed curve of the geared motor.
The required torque output of a geared motor must be within its maximum recommended torque for
continuous duty.
