The pros and cons of the four main EV motor configurations
Electric vehicles (EVs) come in various horsepower ranges, and every EV model released is meant to satisfy a particular application. The applications can start from basic utility to sports utility or medium-duty applications. As such, the motor configuration within each EV is different for different applications. This article discusses the four different motor configurations and…
