| Abstract: | Firstly,the topology and operation principle of the wheel-hub permanent-magnet brushless DC motor are researched in the paper.A general method for decreasing cogging torque by coorperating of pole number and slot number is given.To increase the inner space utilization rate and the motor efficiency,the double-layer-and-short-pitch windings are employed. Secondly, some simulation waveforms are acquired through the 2D circuit-field coupled time-stepping finite-element method.Finally,the experimental results of the motor prove the reliability of design and analysis. |
