ABSTRACT:
A magnet assembly for a permanent magnet direct current electric motor has two arcuate members positioned in a cylindrical frame by a pair of spring clips which maintain the position of the arcuate member within the frame prior to magnetization of the arcuate members. Each spring clip has circumferentially extending primary spring arms, radially extending secondary spring arms and an arcuate base portion to which the secondary spring arms are integral with. The primary spring arms bear against radial side faces of the arcuate members and the arcuate base portion is substantially aligned with the inner surface of the arcuate members. The spring arms provide a range of deflection which permits a wider tolerance on the arcuate members.
