Study on design and flux weakening control of direct drive hub motor

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 air gap magnetic density other performance were carried out. results not only verify rationality design, but also provide basis next study on flux weakening show prototype meets requirements fully.
