ROTOR CORE ASSEMBLY FOR A RELUCTANCE MOTOR AND MANUFACTURING METHOD OF THE SAME

摘要

A rotor core assembly for a reluctance motor and a manufacturing method of the same, wherein the rotor core assembly has multiple silicon steel laminations and a nonmagnetic material. The silicon steel laminations are axially stacked, and each silicon steel lamination has multiple magnetic flux sections. Each magnetic flux section has multiple arcuate grooves and multiple salient poles. The arcuate grooves are concentrically arranged. The salient poles protrude into the grooves. The nonmagnetic material is disposed in the grooves, and is wrapped around the salient poles, which enables the silicon steel laminations to remain securely assembled together. The salient poles are disposed in the grooves to avoid ruining the magnetic line of force. As a result, the rotor core assembly can keep rigidity of the assembled silicon steel laminations, and can keep the integrity of the magnetic circuit.
