ABSTRACT:
A motor with an auto output adjusting device. This motor has a plurality of stator independent coils to drive the rotor separately and a torque sensor sensing how large the load of the machine the motor drives is and commanding an electric circuit for adjusting the number of said stator independent coils to get electricity according to the load sensed by said torque sensor. Then this motor can economize the electric power by cutting down the current used in driving the machine when the machine is working idle or below its maximum load.
