How to eliminate the electromotive force of ac motor
It is wrong to eliminate the anti-electromotive force of ac motor, which is the electromotive force that is opposite to the electromotive force of the power supply. There are multiple power sources in the circuit that can be turned against electromotive force. For example, two metal bars that cut the magnetic field in the same way back to the road may have an anti-electromotive force. There may be an anti-electromotive force in the presence of the electromotive electromotive force and induced electromotive force. In the case of a coil, the current of the electric current changes in the end of the coil. For example, the variation of voltage between the inductors in the LC oscillator circuit is strongly associated with the anti-electromotive force. The electromotive force is also produced when the motor coil is turning.
Motor is to understand the principle of junior high school, is a device that converts electrical energy into mechanical energy, electric coil in the magnetic field by the magnetic field of the ampere force function, makes the pivoting coil. Ampere is the power source for the rotation of the coils. If we only see the dynamic function of ampere force, the coil of the motor will continue to accelerate, this is clearly impossible, because each has a maximum speed of the motor
You have a fundamental error in this question. There must be an anti-electromotive force in the motor running as an electric motor. If you want to run the motor, you don't have a countercurrent, so the motor is running as a generator.
