Abstract
A method of magnetizing a permanent magnet motor involves inserting a spacer in between multi-layered windings ( Ua and Va) wound on a plurality of magnetic pole teeth when magnetizing an unmagnetized magnet ( ), and removing the inserted spacer ( A) after finishing the magnetization. The spacer ( A) is also inserted in a space between two stator windings ( Ua, Va; Ub, Vb) wound on two magnetic pole teeth adjacent to each other, a magnet material is magnetized by electrifying the stator windings with a direct current in a state of the spacer ( A) being inserted, a permanent magnet is thus formed, and the spacer ( A) is removed after finishing the magnetization.
