Bockwoldt motor Germany Bockwoldt model Bockwoldt price

Bockwoldt motors are a type of electric motor powered by simultaneously connecting to 380V three-phase AC current (phase difference 120 degrees). Because the rotor of a three-phase asynchronous motor rotates in the same direction but at a different speed than the stator's rotating magnetic field, there is slip, hence the name three-phase asynchronous motor. The rotor speed of a three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor windings generate electromotive force and current due to relative motion with the magnetic field, interacting with the magnetic field to produce electromagnetic torque, achieving energy conversion.
