Permanent Magnet Synchronous Motor Solutions for Automotive Applications including X-by-Wire Systems

摘要

This paper presents an overview of actual high performance permanent magnet synchronous motor (PMSM) based electric drives for automotive applications. The field of applications spans a broad range from active steering, power steering, electromechanical brakes, clutch and shift actuators, suspension, damping and stabilization actuators, heating, ventilation, and air conditioning up to starter-generators and traction, including topics like steer-by-wire, and brake-by-wire. Most of these applications require high performance motors with a high torque/volume (mass) ratio, low inertia, high dynamics, good field-weakening and high temperature capability. A wide spectrum of solutions is offered in the present work. Aspects regarding performance, motor design and control, materials, technology and costs are discussed. Design details and experimental results for the case study prototypes are also presented.
