- The motor shown operates at constant speed and develops a torque of 100 lb-in during normal operation. Attached to the motor shaft is a gear reducer of ratio 5:1, that is, the reducer output shaft rotates in the same direction as the motor but at one-fifth motor speed. Rotation of the reducer housing is prevented by the "torque arm" pin-connected at each end as shown. The reducer output shaft drives the load through a flexible coupling.
