ABSTRACT:
A brushless DC motor, having a rotor with a cylindrical rotor magnet supported rotationally by a shaft held by bearings mounted on a substantially planar base plate, and a stator supported by the base plate, and including a plurality of radially spaced salient poles holding stator coils formed by windings of magnet wire. Opposing surfaces of the rotor and each salient pole are defined by a first surface of a magnetic core of the salient pole, which is received in a bobbin, and a second surface of the magnetic core orthogonal to the first surface, and the rotor magnet has permanent magnet poles forming a first surface opposing the first surface of the magnetic core, and a second surface opposing the second surface of the magnetic core. A tip of each magnetic core is received through a hole formed in the base plate.
