Abstract
A motor and an application apparatus are provided. The motor includes a stator having a stator core and a stator winding wound on the stator core, a rotor, a magnetic sensor configured to detect a magnetic field polarity of the rotor and output a corresponding signal, and a motor driving circuit configured to drive the rotor to rotate with respect to the stator based on the signal output from the magnetic sensor. At a rest position of the rotor, the magnetic sensor is arranged with an advance angle with respect to a polar axis of the rotor, to make the motor have a high starting torque.
