Abstract: A brushless motor includes a stator core having 3M teeth, with M being an integer not less than 2, a rotor received in the stator core, 3M coils respectively wound around the 3M teeth, and a printed circuit board (PCB) fixed to the stator core and electrically connected to the 3M coils such that the 3M coils are connected in delta and correspond to three phase windings. Each phase includes at least two coils connected in parallel.
