The hysteresis synchronous motors have attracted the attention of the nuclear industry due to their advantages such as low noise, high mechanical strength, and group feed capability. These motors have some disadvantages such as low power factor, low output torque, low efficiency, and the hunting phenomenon that created fundamental limitations in related industries. One of the most practical methods to decrease the shortcomings of the hysteresis motor is to combine it with a permanent magnet synchronous motor. This hybrid motor is called a permanent magnet hysteresis synchronous motor (PMHS). In this article, a permanent magnet disc will be added to the hysteresis motor to form the PMHS motor. Then, by performing several experiments on two hysteresis and PMHS motors, the performance of each will be analyzed and evaluated. Experimental results show that by combining a permanent magnet motor with a hysteresis motor, the defects of the hysteresis motor are significantly reduced and the new motor performs much better than the hysteresis motor.
