1. An electric machine comprising:
- a housing;
a stator mounted within the housing;
a rotor rotatably mounted within the housing relative to the stator;
a plurality of vibration sensors integrated into the housing at multiple positions, each of the plurality of vibration sensors including a sensing member configured and disposed to detect vibrations of the electric machine; and
a controller operatively connected to each of the plurality of sensors, the controller being configured and disposed to determine a relative motion of the electric machine based on the vibrations sensed at the plurality of vibration sensors.
