To maintain a motor, use well-lubricated bearings to keep the motor running smoothly and efficiently.
Rotor is the rotating unit of a motor, while a stator is the stationary portion of the magnetic circuit and associated windings.
In constant torque applications, as the speed changes, the load torque remains constant and the horsepower changes linearly. This can be seen mostly in blowers, fans, conveyors, crushers and constant displacement pumps.
