For high-speed permanent magnet machines (HSPMMs), two different rotor structures are widely used: surface-mounted (SPM) and interior (IPM). The have a large impact on the comprehensive performance in multiple physical fields of HSPMMs, including mechanical stress, electromagnetic characteristics, temperature distribution. However, multi-physics comparison is rare existing literature, which mak...

This paper proposes a direct power control scheme for an offshore wind turbine-driven surface-mounted permanent magnet synchronous generator with full back-to-back converter situated onshore to decentralize the weight of turbine. The proposed model is designed in stationary reference frame and does not require phase-locked loop as opposed traditional vector current method. Simple feed-forward f...

This paper investigates the influence of the power converter on the performance of Surface Mounted Permanent Magnet Synchronous Motor Drives, which employ High Frequency Voltage Injection to achieve low speed control. The effects of IGBT voltage drop, deadtime and deadtime compensation on position estimation are discussed and the use of Matrix Converter is proposed to reduce these effects. Spac...
