Abstract
A sensor assembly for an electric machine includes a position sensor mounted to the stator. The sensor assembly further includes a target configured to be inductively coupled to a transmit coil of the position sensor and a plurality of receive coils of the position sensor when the target passes the position sensor during a revolution of the rotor relative to the stator. The sensor assembly includes a circuit mounted to the rotor. The sensor assembly further includes a power generation element on the rotor. The power generation element generates electrical power needed for powering electronic components of the circuit based on an inductive coupling with the transmit coil when the power generation element passes the position sensor during the revolution of the rotor. The electronic components can include a sensor configured to obtain data that can be communicated to the position sensor mounted to the stator.
