An electric motor is a device that converts electrical energy into mechanical energy. It consists of a rotor, which rotates when an electric current is passed through it, and a stator, which generates a magnetic field that interacts with the rotor to produce movement. Electric motors are commonly used in a wide range of applications, such as in transportation vehicles, industrial machines, and home appliances. They are typically more efficient and reliable than internal combustion engines, as they produce less waste heat and have fewer moving parts. Electric motors also produce no direct emissions, making them a popular choice for environmentally-friendly technologies. Advances in electric motor technology have made them increasingly powerful and versatile, and they are expected to play a key role in the transition to renewable energy sources and sustainable transportation systems.
