Summary: The issue of bearing current in wind power generation system is investigated in this study. By studying the internal structure of a 5.5 MW wind-turbine permanent magnet synchronous generator, a bearing voltage equivalent circuit is established. A method for extracting cable parameters, generator winding parameters, and stray capacitance parameters based on experiments is proposed to simulate the system. A test platform is built to measure the common mode voltage, common mode current, and bearing voltage, and the results are compared with simulation results in both time and frequency domains. The common mode equivalent model accurately simulates the actual bearing voltage. Furthermore, the use of rotor flange insulation is proposed as a strategy to suppress bearing voltage, and an optimization design method for this suppression scheme is presented.

Summary: In this paper, a novel mechanical flux-weakening design of a spoke-type permanent magnet generator for a stand-alone power supply is proposed. The total induced voltage can be effectively adjusted by controlling the position of the adjustable modulator ring, enabling variable-speed constant-amplitude voltage control.

Summary: This paper analyzes the performance of vehicle motors considering operating conditions, summarizes the design rules of reverse-salient permanent magnet synchronous motors (RSPMSMs), and proposes an RSPMSM. The principle of the RSPMSM with high torque, especially in flux-weakening states, is studied by analyzing variable flux leakage and variable saliency ratio in detail. The electromagnetic performance of the proposed RSPMSM is investigated using the finite element method (FEM), and its prototype is manufactured and tested. Experimental results show a constant-power speed range of 5.5:1 and a power factor close to 1 at high speeds, making the RSPMSM a favorable candidate for electric vehicles (EVs).

Summary: In this article, a synchronous pulsewidth modulation control method is proposed to reduce the electromagnetic vibration and loss caused by space and time harmonics in permanent magnet synchronous motors. The proposed method cancels out the pulsation caused by space harmonics by shifting the carrier wave phase and matching the vibration frequencies. Experimental results show a 46% reduction in vibration at a specific frequency. Additionally, the magnet eddy-current loss is reduced, leading to a 5 K decrease in temperature rise.
