Abstract
A motor includes a base plate, a stator, a rotor, a circuit board and a Hall element. The stator is disposed on the base plate. The rotor is disposed around the stator, and includes a rotating shaft and a magnetic assembly. The rotating shaft is extended to a center part of the stator. The magnetic assembly includes plural magnets. The circuit board is arranged between the stator and the base plate and comprises a Hall element. A first gap and a second gap are arranged between every two adjacent magnets. The first gap is in the vicinity of the Hall element, and opposed to the second gap. The distance of a vacant portion of the first gap is shorter than the distance of the second gap, thereby facilitating continuous and steady magnetic induction between the Hall element and the magnetic assembly.
