Abstract

See full text

A rotor of line start permanent magnet synchronous motor is provided. The rotor includes bars of cage windings. The rotor includes an additional inductance coupled to the cage windings and located on a first end of the bars. The rotor includes an end ring located on a second end of the bars. The additional inductance provides a reactance to reduce a starting current during an asynchronous starting of the line start permanent magnet synchronous motor.
