The magnet is formed as a single piece including a first pair of poles having a first north pole face and a first south pole face, and a second pair of poles including a second north pole face and a second south pole face. The first north pole face is adjacent the second south pole face, and a pole junction is defined between the first and second pairs of poles. A sensor is configured to detect the pole junction. A controller is configured to control the motor based on detection of the pole junction.
