Abstract
A motor includes a rotor housing, at least one magnet operably coupled to the rotor housing, a stator disposed within the rotor housing, and at least one sensor. The magnet corresponds to a rotor pole that provides a magnetic flux including a main flux and a leakage flux. The stator includes a plurality of stator poles. The main flux is configured to extend in a first direction towards at least one of the stator poles. The at least one sensor is configured to measure the leakage flux. The leakage flux is configured to extend in a second direction towards the at least one sensor. The first direction lies on a radial plane and the second direction lies out of the radial plane.
