Abstract

This paper presents a novel dual-structure permanent magnet machine which has the distinct merits of having a compact structure with high power and torque densities. Sensorless control of this proposed machine at low speed and standstill is realized based on the indirect flux estimations by online reactance measurement (INFORM) method using transient finite element (FE) analysis. An external power electronic circuit controlled by a digital signal processor is coupled with the FE machine model to compute and analyse the stator current variation and real-time inductances. Hence, the rotor position detection strategy of the machine can be optimally designed.
