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