Driverless cars are expected to become a reality over the next 20 years. The sub-systems within these vehicles will require increased fault tolerance and capability. This is in addition to the already high reliability, efficiency, and performance of today's systems such as electric power steering (EPS). This paper presents a motor design development of such an auxiliary system. Predicted performance of various double-layer and single-layer options are presented and contrasted.
