Title:

ROTOR AND SYNCHRONOUS RELUCTANCE MOTOR HAVING THE SAME

Document Type and Number:

WIPO Patent Application WO/2017/129097

Kind Code:

A1

Abstract:

A rotor and a synchronous reluctance motor having the same, mainly configured to improving upon the issue of serious magnetic-flux leakage in existing rotors. The rotor of the synchronous reluctance motor comprises a rotor core (1), the rotor core comprising a plurality of magnetic-flux barrier groups (11); each magnetic-flux barrier group comprises at least two magnetic-flux barriers (11a, 11b, 11c) provided at a spacing in a radial direction of the rotor core; the magnetic-flux barriers extend to the outer edge of the rotor core and form an opening at the outer edge of the rotor core; the rotor core further comprises a magnetic bridge (13); the magnetic bridge is disposed within the magnetic-flux barriers and connects the inner surfaces and outer surface of the magnetic-flux barriers, and the distance between the magnetic bridge and the outer edge of the rotor core is no less than a predetermined distance. The rotor and the synchronous reluctance motor having the same may reduce magnetic-flux leakage of the rotor, thereby enhancing the strength of the rotor.
