Định Nghĩa và Ý Nghĩa của "motor"

What is a "motor"?

A motor is a device that converts electrical energy into mechanical energy to make something move. In vehicles, motors are used to power things like electric cars, where they replace the traditional engine. Motors work by using electricity to create motion through magnetic forces, which drive the vehicle's wheels. Unlike an engine, which relies on burning fuel, a motor typically uses electricity from batteries or another power source. Motors are also found in various machines and appliances, such as fans, pumps, and power tools, to make them operate. The efficiency of a motor affects the overall performance and energy use of the device it powers.
