A New Two Separate Rotor Axial Flux Permanent Magnet Motor; Analysis and Performance Comparison

Increasing the influence of electrical motor drives in various applications especially in the transportation industry, have led to the growing use of permanent magnet motors because of its many advantages, such as high gain, more power and torque density. In order to improve the performance of these drives in a different load conditions, introducing new structures with greater flexibility and capability is highly felt. This paper studied changes in the mechanical structure of double sided disc type permanent magnetic motor, so that two rotor discs can have independent bearing and axis. The performance results of the simulations presented in this paper shows that new structure motor with two degrees of freedom dynamic can rotate two different loads at equal velocities without encountering stability problems. It is expected that this new structure with flexible feature in the management of the mechanical load of each axle, without having a significant impact on the functional characteristics of the motor, will lead to increasing the usages of this motor.
