For the commercial production of a claw-teeth motor with three-dimensional powder magnetic cores, the design of motors with high-density and high-strength powder magnetic cores were verified by a test motor. The high strength is to focus on the shaping stress of the press die, and employ the stress values of every part to obtain the design of motor core shapes that can guarantee the desired molds life that is shown by the relation between stress and mold life according to the materials endurance strength distribution. Furthermore, the high strength, which is obtained by the high-strength process, can make sure that the strength of the flat claw-teeth core that has a complicated shape is at a high level to meet the requirements of factory work. With these considerations, the test motor with the designed claw-teeth cores meets all the design requirements.
