According to the operation principle of the motor, the through-flow conductor rotates under the action of force in a magnetic field, induced electromotive force E generated after rotation is equal to Ce phi n (n is the rotating speed of the rotor relative to the stator, namely the rotating speed difference between the rotor and the stator), and electromagnetic torque T generated after rotation is equal to CT phi Ia (Ia is armature loop current). A voltage balance equation (taking a shunt excitation DC motor as an example) in a motor loop after rotation is U = E + IaRa. (Ra is the internal resistance of the armature circuit). At the moment, if the rotating speed n is reduced, the induced electromotive force E is reduced, and if the input voltage U and the magnetic flux phi in the magnetic field are kept unchanged, the armature current Ia is increased, so that the electromagnetic torque T is increased, and the correctness of the theory is verified by an author through a test. According to the scheme, the motor stator is driven to rotate by inertia force during automobile running, the rotating speed difference n between the stator and the rotor is reduced, and therefore electromotive force E is reduced. As the speed difference between the rotor and the stator is very small, very large torque can be generated in the rotor, and electromagnetic loss is also reduced at the same time.
