The theory of the development of torque in a hysteresis motor is analyzed from both the hysteresis lag angle and total loop energy points of view. A new development, comprising the use of a closed slot stator in co-operation with a hysteresis rotor, which permits building hysteresis motors of high power output at high efficiency is explained qualitatively and supplemented by considerable quantitative experimental data. A new method of stator construction, permitting the use of closed slot… 
An Experimental Comparison of Disc-Type Hysteresis Motors With Slotless Magnetic Stator Core
This paper comparatively examines the operational characteristics of several disc-type hysteresis motors with slotless stators, and recommends a suitable motor for each application based on four key criteria.
Some Aspects of the Design and Operation of the Polyphase Hysteresis Motor
The hysteresis motor can be considered as a self-starting synchronous motor that produces a synchronizing torque and an ideally flat speed/torque characteristic from the time of starting until it reaches synchronous speed.
Circumferential Flux Type Hysteresis Motor with Rotor Ring of Copper Sprayed Surface Layer
There are two purposes in this paper. The one is to divide the rotor of the hysteresis motor for the improvement of the characteristics. The divided rotor has slits inside the rotor ring as many as
A novel time varying dynamic modeling for hysteresis motor
A new time varying Dynamic model for a high-speed, circumferential- flux type hysteresis motor, in which the parameters of equivalent circuit of rotor's material are adjusted based on operational B-H loop.
Analysis, Design and Optimization of Hysteresis Clutches
Electromagnetic clutches are widely used devices in industrial applications when a torque must be transmitted between two components without mechanical contact avoiding friction and so reducing wear
