Abstract

A turn wound around each pole of an SPM motor allows the direct axis flux linkage dynamics to be modified while preserving the quadrature axis one. Thus, a rotor dynamic anisotropy is created. Consequently, the motor can be used in a position sensorless control which exploits the anisotropic rotor features by high frequency injected signals. The model of the machine is described in the paper, and the main equations describing the motor dynamics are reported. Simulations, design hints and experimental results are reported so as to validate the proposed new rotor structure.
