The direct drive hub motor is a that directly combines the and wheel. It accompanied by development of permanent magnet modern control technology. Permanent synchronous (PMSM) especially suitable for use as its advantages high efficiency, energy saving, power easy control. In this paper, Motor Cad software was applied to optimize design an outer rotor PMSM cellular power, simulation analysis ai...

Two novel structures of permanent magnet (PM) machine, namely a hybrid excitation flux modulation machine (HEFMM) and a variable flux memory machine (VFMM), which have excellent field-weakening capability, are presented in this paper. The HEFMM incorporates the advantages of parallel hybrid excitation structure and flux modulation structure, so as to increase the torque density as well as incre...

This article presents an enhanced flux weakening (FW) control scheme for permanent magnet synchronous motors, focused on electric vehicle applications. The novelty of the proposed algorithm is integration in a unified both accelerator pedal as torque reference and cruise speed limiter limit, without interfering between them until this limit achieved. <italic xmlns:mml="http://www.w3.org/1998/Ma...
