Abstract

The invention discloses a time-varying torque and time-varying load motor technology which is characterized in that a basic motor and a plurality of motors to be worked are coaxially arranged in a machine. The basic motor of the running motor is combined with a plurality of motors to be worked, which are determined by the input torque and the load of the rotating shaft, namely when the rotating shaft of the generator is acted by time-varying torque, the basic motor is automatically matched with the rotating speed, the output power and the current of the rotating shaft of the generator and the rotational inertia of an equivalent rotor, so that the phenomenon that the rotating inertia of the rotor of the traditional generator is dead due to the fact that the torque of the rotating shaft is reduced because the rotational inertia is constant and the phenomenon that the energy consumption proportion of the motor is overlarge when the load of the rotating shaft is too small in the rated output power of the motor are avoided. When the load is changed, the matching values of the electricity and the machinery are automatically adjusted. The invention also discloses a manufacturing method of the motor.
