The ongoing electrification of the automobile is not limited in substituting only the combustion engine. There is also an enormous impact on the development of auxiliary devices. So far it was common to use small DC-motors as actuator for the low power applications such as window openers, seat adjusters or ventilators. Meanwhile, also influenced by the ongoing discussion to increase the on-board voltage to 48 V, even former belt driven auxiliary devices with high energy consumption are being replaced by highly optimized mechatronic modules driven by BLDC-motors. Since these components are produced in a large volume and have to fulfill severe requirements regarding product performance, manufacturability and cost, a multi-domain optimization on system level is important. This article describes one aspect of the optimization process regarding the winding and connection concept of the BLDC-motor.
