| Summary: | The purpose of this work is to develop a thin, electromagnetic wobble motor with a large amount of torque, a motor thinner than conventional ones and able to be applied to portable electric equipment. We have developed a basic model of the motor 30 mm in diameter and 5 mm in thickness. In this paper, the basic structure and control method are first presented. Next, the design of the electromagnets and the three types of gear pairs, which have different pressure angles for the reduction mechanism, are presented. Finally, the motor drive experiments are performed using two types of drive: one is a two-phase drive, and the other is a four-phase drive. Three types of gear pairs are also shown. The motor works successfully, and its great potential to be mounted in thin, portable equipments is confirmed. |
