Abstract
A motor system includes a brushless motor with a stator, a rotor having a first number of rotor poles, and a motor shaft connected to the rotor. The motor system also includes control electronics configured to control a brushless motor that has a second, number of rotor poles, different from the first number of rotor poles. The second number of rotor poles is an integer multiple, N, of the first number of rotor poles. A position sensor is communicatively connected to the control electronics. A first gear is mounted on the motor shaft and connected for rotation with the motor shaft, the first gear having a first number of teeth. A second gear is engaged with the first gear, the second gear having a second number of gear teeth. The position sensor is configured to detect an angular position of the second gear and provide it to the control electronics.
