Analyze whether the electric car is DC or AC

May 02, 2019

Regarding the electric power supply of the electric vehicle is DC or AC point, from the professional point of view, the DC is in front of the controller, the input motor is AC, and then the controller is frequency-converted. The 220v inverter is also the first DC variable frequency to change the frequency, the electric vehicle The motor is a three-phase AC synchronous motor with a star winding. Although the electric vehicle uses a DC power supply, the motor does have an AC-DC distinction.

 

Observing the motor leads of an electric motorcycle can be found in two cases. One is only two thick lines, this is a brush motor, which is a DC motor. Second, there are three thick lines plus five thin lines. This is a brushless motor. It is also called an AC motor.

 

Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, an electric vehicle uses a battery as a source of energy, and converts electrical energy into mechanical energy through a controller, a motor, and the like to control the current to change the speed of the car. Electric vehicles can be divided into: electric bicycles; electric motorcycles; electric unicycles; electric tricycles; electric scooters; pure electric vehicles; extended-range electric vehicles; hybrid electric vehicles; fuel cell vehicles. Classified by usage: electric vehicles; electric tricycles; electric bicycles.www.guoweimoto.com
