Double stator double rotor permanent magnet synchronous machine with claw pole arrangement for inner rotor

摘要

Described herein is a permanent magnet synchronous machine (100, 200, 300) comprising a rotor assembly comprising an inner rotor (126, 226, 326) having rotor windings (118, 218, 318), and an outer rotor (128, 228, 328) having permanent magnets (112, 212, 312) arranged therein, and a stator assembly (130, 210, 330) comprising a stator core, inner stator windings (120, 326) and outer stator windings (122, 332), wherein the inner rotor and the outer rotor are mounted coaxially with a shaft (102, 202, 302) and the stator core, wherein the stator assembly is selected from the group consisting of a slotted configuration, a slot-less configuration, a magnetically isolated configuration and an air-cored configuration.
