Abstract

This paper presents a feasibility study towards a control technique for a multi-phase machine with independent windings, so-called winding reconfiguration, for application in fully electric vehicles. The goal is to shift the point where field weakening is necessary and avert its dangers, extend the constant-torque region of the machine, and eliminate the torque-pulsations associated with gear shifts. The winding reconfiguration technique is modeled, and compared with measurement data obtained on a test setup featuring a six-phase machine.

Funding

This work is conducted under the European Union Modular Electric Drivetrains project, and explains an alternative to the traditional three-phase electric machine and multi ratio gearbox approach [4]. In this approach, a multi-phase electric machine is paired with a fixed ratio gearbox. The additional freedom of the multiphase machine is used to achieve different gear ratios This paper is part of a project that has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 769953
