Title:
FAULT-TOLERANT MODULAR PERMANENT MAGNET ASSISTED SYNCHRONOUS RELUCTANCE MOTOR AND MODULAR WINDING DESIGN METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/205733
Kind Code:
A1
Abstract:
Disclosed are a fault-tolerant modular permanent magnet assisted synchronous reluctance (PMa-SynR) motor and a modular winding design method therefor. The present invention belongs to the field of PMa-SynR motors. For the stator modular design of the PMa-SynR motor, by means of changing the inlet and outlet of each phase winding coil based on the slot potential star graph phase separation, each module unit has an independent set of windings, and the windings of each module take the left-right opposite distribution form. The advantages of the present invention are in achieving real modularization in structure, having high inter-module independence, effectively avoiding the occurrence of overlapping the inter-module magnetic lines, and improving the fault tolerance and reliability of the motor. Therefore, the disadvantage of low fault-tolerance of the distributed winding structure motor can be solved, and is of great significance and practical value.
