Question:

Electric cars can not move what is the reason?

Electric cars can not move what is the reason?

Answer:

The permanent magnet DC motor has a characteristic, it can be used as a drive motor, can also be used when the engine, once the motor negative short circuit, the equivalent of the motor to form a closed loop, if you push the electric car to go
Wheel rotation is equivalent to the power generation, and positive and negative short circuit is short circuit current, so it will produce a great resistance at this time. As the short-circuit current is very large, it is easy to burn out the components of the motor, so it should be avoided as soon as possible, and then push off the positive and negative wires. If it were not for other mechanical problems, that would be the main reason why the electric car could not move.
Use this principle, some manufacturers of electric cars designed a special circuit, intentionally locked positive and negative, so that the car can not push, for anti-theft. Other manufacturers use the principle that electric motors can generate electricity, allowing the electric car to power down the hill and brake and return it to the battery to increase mileage
