• Resumen

  • Purpose This paper aims to propose a new topology of direct current (DC) machine using claw-pole stator to replace standard DC starter in micro-hybrid vehicles. The main interest of such a topology is the reduction of copper volume.

    Design/methodology/approach The design of the claw-pole machine is based on a multi-objective optimization of several topologies, based on a three-dimensional (3D) reluctance network modeling. The 3D finite element (FE) model is used to check the results of the optimization, and a prototype is manufactured and tested with satisfactory results.

    Findings The claw-pole topology with wave-shape windings allows to replace the current DC series classical starter because of to its copper volume saving.

    Research limitations/implications This model is only limited to the optimization of the claw-pole stator for a fixed geometry of the rotor.

    Practical implications The research outcome shows that claw-pole machine can replace the series-excited DC machines of starters and at the same time achieve the same performance at reduced copper volume.

    Originality/value The paper deals with a new DC machine topology to reduce the copper volume through the suppression of the classical stator end-windings. The use of Claw-Pole inductors ensures this copper reduction.
