ABSTRACT:
An electric motor comprises a rotor rotational position indicator formed internally with a pole field portion of a rotor thereof, and a notch disposed between the pole field portion and the rotor rotational position indicator for suppressing the magnetic influence, the notch being filled with nonmagnetic materials. By virtue of the notch, the pole field and its magnetic influence upon a sensor can be suppressed, whereby appropriate home position and incremental pulses can be generated to enable accurate detection of a rotational position of the rotor.
