✦ Synopsis
This paper introduces an axial gap type self-bearing motor. It is intended for a disk type flat motor to have both functions of rotation and axial position control. This motor is simple in construction and requires a simple control system. A permanent magnet type motor is analyzed theoretically and tested experimentally. The torque characteristics of the tested motor are measured at various values of axial force and air gap. Independent control of the axial force and torque is introduced for the servo motor control and synchronous motor control. The results show the high possibility of the proposed motor and control system.
