Hysteresis Self-Bearing Motor

This paper presents a hysteresis self-bearing motor along with its nonlinear analysis. In this work we introduced a new type of self-bearing motor with segmented stator. The major advantages of this stator are: easy and low cost manufacturing, higher filling factor and shorter magnetic path for the stator. We tested the self-bearing concept successfully with this new configuration. Hysteresis motors are suitable for high speed application since their rotor has neither permanent magnets nor any winding or mechanical features. We used FEA analysis to check the feasibility of proposed idea. Then we used Chua’s hysteresis model to simulate the nonlinear behavior of this system.
