ABSTRACT:
A concentrated winding type brushless DC motor has a stator formed by a slack of laminations of a ferro-magnetic material having an outer ring from which a plurality of spaced teeth extend inwardly and have slots between adjacent teeth. A drive coil is wound around each tooth in the presence of a spacer provided between an end surface of a stator tooth and the drive coil to reduce stress applied to a tooth by the coil as it is being wound. The final form of the motor has the spacer removed leaving a space between the coil and the tooth to form a magnetic pole of the stator.
