Induction motors, also known as "asynchronous motors," are devices that place the rotor in a rotating magnetic field and obtain a rotational torque under the action of the rotating magnetic field, thereby causing the rotor to rotate. The rotor is a rotatable conductor, usually in the shape of a squirrel cage. Invented by electrical engineer Nikola Tesla in 1887. The entry introduces the concept, inventor, working principle, basic structure, working mode, braking mode, asynchronous characteristics, specifications, and fault inspection of induction motors.

An induction motor is also known as an "asynchronous motor", in which the rotor is placed in a rotating magnetic field, and under the action of the rotating magnetic field, a rotational torque is obtained, thereby causing the rotor to rotate.
