Summary: This research proposes a new spoke-type interior permanent magnet (IPM) machine with enhanced flux-concentrating capability and high saliency ratio rotor for extended-range electric vehicles traction applications. The comparison and analysis of the electromagnetic performance of two IPM motors with the proposed IPM machine are conducted using finite-element analysis (FEA). The results show that the IPM machine with high saliency ratio rotor achieves higher torque/power, maximum torque per ampere capability, and flux-weakening ability.

Summary: This article describes the rotor shape optimization of interior permanent magnet synchronous motors to reduce rotor core losses and torque ripples. The experimental verification using a prototype motor confirms the effectiveness of the optimization. It is found that optimizing the rotor surface can significantly reduce both rotor core losses and torque ripples under typical driving conditions without considerable deteriorations of the other important characteristics. The design tradeoff mechanism for reducing torque ripples under different driving conditions is also explained.

Summary: This article proposes a model for obtaining the failure path current and torque waveforms in synchronous machines with saliency under interturn short circuits (ISC). A compact approach based on complex numbers is used to solve the dynamic ISC equation, and rotor reference frame variables and parameters are used as inputs.
