Abstract:

A new design of a single-phase flux reversal machine (FRM) and a procedure of mathematical simulation of the FRM are described in this article. Technical features of the FRM (such as efficiency, specific power, and specific torque) that are close to those of synchronous motors with magnets on the rotor have greater reliability for high speed applications. The main advantages of an FRM involve the absence of permanent magnets or electric conductors on a rotating rotor and their being positioned on a stator. The new design of a single-phase FRM consists of a rotor with four teeth and a stator with four teeth and a magnetic system. The magnetic system on the stator teeth surface has two magnets on each stator tooth and generates two magnetic poles on each one. The adjacent poles on the adjacent teeth of stator are similar. The total angular size of new design is slightly less than the perimeter of the circle. Therefore, the stator surface is much better used (unlike the prototype), which results in an increase in the specific power and power efficiency, as well as a decrease in the cost of the FRM. A method for mathematical simulation of an FRM that is based upon solving magnetostatic problems with common geometry is proposed. Different positions of the rotor are simulated by joining boundary conditions. The method allows one to determine the electric losses in steel and magnets in postprocessing. © 2016, Allerton Press, Inc.
