Power Steering: Brushless DC or Switched-Reluctance?
The trend in the automotive industry is to replace mechanically actuated systems with systems based on electric motor technology. The traditional brushed dc motor is not suitable for many of these adjustable speed applications because of the wear associated with the brushes, lower overall power density, and EMI problems associated with commutator arcing. This arcing can become more serious as application requirements move from sub-fractional horsepower to transient integral horsepower. The low system voltage and the resulting high inductive motor currents that the commutator must interrupt can create substantial arcing.
The increase of power electronics components that target the automotive industry (namely, low voltage, high current semiconductors) has motivated automakers and OEMs to consider higher performance motor technologies with the expectation that high volume and improved fuel economy will bring value to the

助力转向:无刷直流或开关磁阻?
这一趋势在汽车行业,以取代机械驱动系统与系统基于电机技术. 传统的刷牙直流电机并不适合许多这些调速应用因磨损相关 与画笔,降低整体功率密度,与EMI相关问题整流子动火. 这动火能够更为严重,由于应用的需求,从亚分数马力短暂积分马力. 该系统的低电压及由此引起的高感应电动机电流换向器必须打断可以创造大量的弧光.
提高电力电子器件,其目标是汽车工业(即低电压, 高电流半导体)已促使汽车制造商和OEM考虑高性能发动机技术,并期望在高容量 和改善燃油经济性将其产品价值. 数份已经看到了广泛接受的12v水平 这主要是因为负荷电流(通常是暂时性)可能是相当高的. 当你经常可以大小的电动马达,其象征性使用,超负荷在短暂的情况, 同一般是不会真正为电力电子技术. 按照规定,电子产品的大小为高峰电力需求的结果昂贵系统 非常反感的汽车.
