Efficient In-wheel Motor Control
Overview
With elimination of bulky transmissions, driveshafts, and differentials in EV’s powertrain, in-wheel motor (IWM) has obvious advantages of high efficiency, driving dynamics, active safety and space saving. This efficient 15kW control system for IWM provides motor position sensor fault-tolerant operation and anti-slip function.
