A new semianalytical method for analysis of the disc-type permanent magnet hysteresis motor in steady-state operational conditions

Considering the characteristics of hysteresis and permanent magnet motors, it seems that these two motors are complements of each other. Thus, their combination yields a motor with an excellent performance. In order to preserve the major advantages of both motors in the new motor, a disc-type slotless structure is chosen. This paper presents a new nite-element method for the modeling of disc-type permanent magnet hysteresis synchronous (PMHS) motor. In this modeling method a new iterative algorithm is used. Programming software has been linked to nite- element software because of its limitation in the modeling of hysteresis phenomena. Validity of the proposed analysis is checked by experimental results. Reasonably close agreement between the two is obtained and good performance of the PMHS motor is veri ed.
