ABSTRACT:
A motor includes a housing formed of a first shell and a second shell, a stator, which is formed of a first yoke, a second yoke, a connecting device and two coils. The first yoke and the second yoke each comprise a terminal holder mounting portion, a race and a plurality of pole pawls respectively extended from the race. The race of the first yoke has the race of the first yoke kept apart from the race of the second yoke at a distance to reduce magnetic interference, the connecting device having a terminal holder fastened to terminal holder mounting portions of the first yoke and second yoke of the stator and a plurality of metal terminals installed in the terminal holder, the coils respectively set between the first yoke and the first shell and between the second yoke and the second shell and respectively electrically connected to the metal terminals, and a rotor formed of a transmission shaft and magnets and inserted through the first yoke and the second yoke and rotatable relative to the stator.
