Patent ID: 6900571

Claim:
A rotor for a synchronous induction motor, comprising: at least one pair of slits forming salient poles in a direction of a d axis in which a magnetic flux can flow easily and in a direction of a q axis in which the magnetic flux can hardly flow; a plurality of slots positioned at an outer circumferential portion of the at least one pair of slits and configured to generate induction torque, one end of each slit of the at least one pair of slits being connected to a respective one of said plurality of slots in the direction of the d axis; a conductive material filled in the plurality of slots and the at least one pair of slits; an output axis positioned at a center of rotation of the rotor; a flat plane positioned at an outer circumference of said rotor in the direction of the q axis; and a reinforcing member having a non-magnetic body positioned at the flat plane and fixed to the output axis, the reinforcing member configured to reinforce the rotor.
