ABSTRACT OF THE DISCLOSURE A printed circuit armature for an electric motor comprising a cylindrical laminated core of low reluctance material. An inner layer of insulating material is concen- trically bonded to the cylindrical laminated core, the inner layer having a plurality of printed circuit conductive elements arranged on its outer surface. An outer layer of insulating material is concentrically bonded to the inner layer of insulating material, the outer layer having a plurality of printed circuit conductive elements arranged on its outer surface, the conductive elements of the inner and outer layers being electrically connected. The conductive elements may be skewed to a maximum of about 3° and the conductive elements of each layer are electrically interconnected so that the forces on the conductive elements, resulting from interaction of the current flowing in the conductors with the magnetic field, cooperate to apply a torque to the armature of the motor.
