Title:
ROTOR FOR SYNCHRONOUS RELUCTANCE MOTOR, SYNCHRONOUS RELUCTANCE MOTOR COMPRISING SAME, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/149668
Kind Code:
A1
Abstract:
The present invention relates to a rotor for a synchronous reluctance motor, a synchronous reluctance motor comprising same, and a manufacturing method therefor, and, more specifically, to a rotor for a synchronous reluctance motor having an improved power factor, a synchronous reluctance motor comprising same, and a manufacturing method therefor. The present invention provides a rotor for a synchronous reluctance motor comprising a stator (400), which has a plurality of winding coils provided on the inner circumferential surface thereof, and the rotor (200), which is provided on the inner side of the stator (400), the rotor having: a flux barrier pattern (220) which includes a plurality of air regions (223) for forming a flux barrier and a plurality of conductor formation regions (221) for forming a conductor (100) by communicating with both ends of the air regions (223), and which is formed in a penetration manner in the longitudinal direction; a plurality of conductors (100), which are injected as a liquid phase into at least one of both ends of the conductor forming regions (221) and coagulate; and the flux barrier pattern (220), which has a blocking region (222) formed between the conductor forming region (221) and the air region (223) in order for a blocking part (310), which prevents a liquid-phase casting from flowing into the air region (223), to be inserted and provided therein.
