System and method for magnetization of permanent magnet rotors in electrical machines

摘要

A system and method for manufacturing an electrical machine (10) is provided. An array of permanent magnet segments (28) is assembled around a rotor spindle (24). Desired orientation directions (29) of the permanent magnet segments (28) are determined. The assembled permanent magnet segments (28) are then positioned in a magnetization fixture (44) such that the desired orientation directions (29) of the permanent magnet segments (28) are aligned with corresponding flux directions (74) of the magnetizing fixture (44).
