In order to solve the problems caused by the asymmetry among phases due to their different relative positions to magnets in the conventional doubly salient permanent magnet motors, two transposition design methods are proposed in this paper, and then employed to the design of doubly salient memory motors which incorporates the concept of the memory motor into the hybrid field excitation doubly salient...
This paper presents a new method which combines the time stepping finite element method (TS-FEM) with the Preisach hysteresis model (PHM) to analysis a new class of flux controllable permanent magnet (PM) machines. The proposed scheme can find consistent states for different history of external applied field sources with more easily numerical implementation. An existing novel doubly salient PM mnemonic...
With the introduction of doubly salient memory (DSM) motors, the flux controllability and hence the speed range of permanent magnet (PM) motors have reached a new height. This paper presents a new method to accurately analyze the DSM motor. The key is to incorporate the general expressions of the Preisach hysteresis model (PHM) of the AlNiCo-PM into the time-stepping finite element method (TS-FEM)...
