Description

A novel stepping motor, AC-excited type stepping motor, is proposed and the fundamental characteristics is described. The new type stepping motor is a VR type and the airgap region between the iron tooth is filled with copper plates. Although the weight of the new type motor is increased by 38 %, the settling time decreases by 22% in comparison with the VR type because of the eddy current induced in the copper plates. Furthermore the torque of the new motor increase in low speed.
