How does the battery of the electric car drive the AC motor?
In addition, this type of motor does not require inverters, the motor itself is a low voltage motor. Want to help you, the specific work principle can refer to the ordinary brush DC motor, the difference is coil winding current commutation instead of controller electronic commutation.
Need to correct it, electric motor is a brushless DC motor drive principle is relatively simple, with the ordinary two wheeled vehicle as an example, the motor outer rotor, is the rare earth permanent magnet, internal stator coil winding is energized, the electromagnetic coil is to produce magnetic force, when a specific set of coils to the rotor magnet, through the Holzer tube (magnetron) controller, to the coils to generate magnetic force (magnetic field and rotor at the same level of) to generate thrust, push the rotor to rotate an angle when rotating the coil after repeated the line behind the winding ring and controller action,
The electric bicycle motor is made up of three pairs of coils, but that doesn't mean an AC motor.The controller controls the speed of the motor by adjusting the pulse width.
