Line start synchronous reluctance motor and rotor thereof

Abstract

The present invention relates to a line start synchronous reluctance motor and a rotor thereof. To this end, the present invention provides a line start synchronous reluctance motor including: a rotor; a plurality of conductor bars disposed on a side of an outer circumferential portion of the rotor; and flux barriers formed at an inner side of the rotor so as to be close to the conductor bars, wherein the flux barriers, which are formed in separate regions of a body of the rotor that are arranged to have opposite polarities, are formed to be asymmetrical to each other. Therefore, the present invention improves characteristics of the motor through the asymmetrical flux-barrier structure without changing the number of conductor bars, thereby allowing the initial starting of the motor to be smoothly performed, which is advantageous in terms of torque ripple characteristics and die casting.
