Hysteresis motors have some distinct advantages such as constant speed and torque, noiseless operation, robust structure, and low-starting current in comparison with other synchronous motors. The main general defects of the hysteresis machines are low efficiency and relatively low-torque density. In this study, two previously proposed structures for the hysteresis motors named 'coreless dual rotor discs hysteresis motor' and 'slotless dual rotor discs hysteresis motor' are compared with each other and with other conventional hysteresis motors from different aspects. Rectifying the iron loss in the coreless type, especially in high-speed applications, and rotor parasitic loss in the slotless type are the most important advantages of these structures. Relative ease of manufacturing process, low production cost, and extendable torque (by multi stack structure) are other significant advantages of these motors. On the basis of two derived optimal designs for the motors, the performances of the motors are compared in different supply voltages.

Recently, the hysteresis motors have a special significance in the nuclear industries. This is because these motors have some advantages such as low noise, high mechanical strength and group feeding ability. They also have some disadvantages that make some limitations for related industries. These disadvantages include low synchronization torque, low power factor, low efficiency, and hunting. One solution to reduce these disadvantages is to combine the hysteresis motor with the PM motor. This however requires a correct and flexible design procedure as well as an appropriate choice of the machine structure. Accordingly, this paper aims to present a new design algorithm for a disc-type permanent magnet hysteresis synchronous (PMHS) hybrid motor. The proposed design algorithm not only tries to retain the positive features of the both motors in the resulted hybrid motor, but it also gives the user the option of determining the percentage of the combination of the two motors. In other words, the user can determine the contribution of each motor to the output power of the resulted motor. The proposed algorithm is finally validated through fabricating a prototype disc-type PMHS motor and evaluating its performance by simulation and experiment.

“…In recent years, the performance analysis of the hysteresis motors is done by the analytical and numerical methods. The analytical methods are widely utilized in the study and performance prediction of electric machines by providing fast and accurate solutions [1], [6]- [8], that are useful in analyzing the hysteresis motors by considering some simplified approximation of the hysteresis loops as an ellipse [7]- [10] or parallelogram [11], [12]. Also, the performance of many common radial flux hysteresis motors (RFHM) have been analyzed by relatively accurate and complicated numerical methods, such as the finite element method (FEM) and the Preisach models, which are also useful to analyze the hybrid hysteresis motors and other type of electrical machines [13]- [20].…”

Axial Structure of the hysteresis motors like the other axial types of electrical machines, have some outstanding characteristics regarding radial structures such as higher torque to weight ratio, excellent efficiency, adjustable air-gap, and balanced rotor-stator attractive forces. Since, the accurate measurement of the hysteresis machine characteristics by prototyping and testing is expensive and time consuming, in this paper the finite element analysis is adopted for the prediction and analysis of an axial flux hysteresis motor. The analysis is conducted based on the elliptical approximation of the hysteresis loop. Whereas, the elliptical approximation is not able to model the saturation of the hysteresis loop, an iteration based method is proposed to overcome this problem and increase the analysis accuracy. Finally, in order to investigate the proposed model accuracy, the device is prototyped whose experimental results agree well with those extracted from the analytical model.Index Terms--Axial flux, hysteresis motor, magnetic hysteresis, numerical models, finite element analysis, and torque calculation R.
