Electric motors
The electric motor is the main element of the electric drive. In some operating modes of the electric drive, the electric motor performs the reverse energy conversion, that is, it operates in the mode of an electric generator. By the type of created mechanical motion, electric motors are divided into rotating, linear, etc.
