More Information
Summary:A brushless motor includes a plurality of stator armature windings having winding frames with spaces defined therein, respectively, a rotor mounted on a rotatable shaft and having field poles rotatable with respect to the armature windings, and a plurality of rotor position detectors such as Hall-effect devices disposed in the spaces, respectively, and having output terminals connected respectively to the input terminals of other armature windings, for continuously varying the currents flowing through the other armature windings dependent on signals indicative of the magnetic fluxes from the field poles as detected by the rotor position detectors.
