Brushed-DC Electric Machinery for Automotive Applications

Abstract

Electric motors have played a crucial role in the evolution of the automotive industry. Existing trends in more electrification of automobiles indicate a further increase in deployment of electromechanical energy devices in coming years. Due to historical, technical, and economical incentives DC-brushed machines have been the favorite choice for numerous automotive applications ranging from starters to auxiliary devices. Ease of control, capital investment, and relatively low cost of manufacturing compared to other energy conversion devices are among the main reasons to justify the substantial use of DC-brushed machines, as advanced motor drive technologies emerge. Although maintenance and durability are still considered as main impeding factors, an impressive compactness and relative high efficiency seems to be of higher significance in the automotive industry. Introduction of power electronics into automotive products over the past two decades has further paved the road for high-grade performance and flexibility in four-quadrant applications. However, it must be mentioned that DC-brushed motor drives are primarily employed for smaller size motors; hence, the design practices should be done in the context of the application to maintain engineering and commercial sense. This necessitates an investigation of drive performance in the presence of the high temperatures that are typical in automotive applications. The present chapter provides an overview of the fundamentals, magnetic design, and control practices for DC-brushed motor drives. Due attention is given to permanent magnet DC-brushed motor drives, as they represent the dominant magnetic configuration used in most automotive DC-brushed motors.
