Abstract
An electric machine includes a rotor assembly having a rotor shaft disposed along a central axis. The electric machine includes an inductive position sensor having a sensor target that is operatively connected to the rotor shaft. The sensor target is fixed relative to the rotor shaft such that the sensor target rotates with the rotor shaft. The electric machine includes a stationary member and a rotating member operatively connected to the rotor shaft. The rotating member is spaced from the stationary member by an air gap. The stationary member and the rotating member are configured to enable non-contact power transfer from the stationary member to the rotating member through the air gap. The non-contact power transfer may be an inductive power transfer or a capacitive power.
