Abstract
Magnetic bearings can support rotating shafts without any contact and have been used in harsh conditions such as in cryogenic and clean environments. In this paper, consequent-pole type self-bearing motor is proposed. It is possible to control the rotor radial positions without the rotational magnetic field of the rotor. Moreover, use of the thick permanent magnets in the consequent pole rotor slots can be avoidable for its demagnetization. The three-dimensional magnetic field analysis using the finite element method carried out. In the results of proposed model2, it is confirmed that the motor torques, radial control forces, and axial control forces accomplish the target value of an artificial heart pump.
