Abstract
A motor stator includes a stator core and a number of stator windings. The stator core includes a stator yoke and a plurality of stator tooth wrapped by a bobbin formed with an over-molding process, and further correspondingly wound around by stator windings. The stator teeth are connected to an inner surface of the stator yoke. A motor including the above motor stator and a rotor is also provided. The rotor includes a rotor core and a rotary shaft fixed relative to the rotor core. The rotor core is received in the bobbin and in magnetic coupling with the stator teeth.
