Abstract

This paper considers the design of an open-slot, external-rotor radial-flux brushless permanent motor based upon a single-layer concentrated ‘modular’ winding. The magnetic circuit design of the most promising pole-slot combinations has been optimised using a procedure comprising a genetic algorithm coupled to a parametric finite element model. The best combinations of pole and slot numbers are presented for which the torque per volume is maximal and torque ripple is minimal. The outcome of the research has been applied to the design of a prototype 24-slot 28-pole motor configured as wheel hub drive for use in a hybrid solar assisted bicycle. The attributes of the design are assessed using test results obtained from this purpose built hub-motor.
