Abstract:Modular permanent-magnet (MPM) motor is a new class of PM brushless machine for drive applications requiring high reliability. MPM machines offer the advantages of high power density and fault-tolerance. In this paper, the machine topology is presented and its fault-tolerant characteristic is analyzed. Moreover, the output power equation is derived analytically, and the optimal design of machine dimensions and parameters for maximum torque per volume are also discussed. Furthermore, to predict the electromagnetic performance of the designed machine, finite-element analysis and coupling field-circuit co-simulation methods are adopted. Finally, a four-phase MPM machine is built and tested for verification. Both simulation and experimental results are given to verify the theoretical analysis. This work lays a foundation for the operation control of MPM machines.
