Abstract
A small motor controller (SMC) system includes a motor configured to control a position of a rotor, a sensor configured to detect position information of the rotor by detecting a feature on the rotor, the sensor including a detection zone having a first side and a second side, and a motor control unit. The motor control unit is configured to determine a position of the rotor corresponding to one of the first side of the detection zone and the second side of the detection zone based on whether the feature on the rotor is detected crossing the first side or the second side, respectively.
