Publication number: 20050046296Abstract: An electric motor is disclosed wherein a positive magnetic pole winding and a negative magnetic winding for each of plural phases in each of two systems are wound respectively around two teeth adjoining each other of those teeth which are arranged circumferentially on an internal surface of a stator to protrude radially inwardly. Thus, in either one of the case that the rotor is rotated by the excitation of all the windings in both of the two systems and the case that it is rotated by the excitation of the windings in either one of the two systems, the windings adjoining each other serve as a set and magnetically attract the rotor thereby to rotate the same. In either case, the position sensor is able to precisely detect the position of the rotor relative to the windings.Type: ApplicationFiled: August 5, 2004Publication date: March 3, 2005Applicants: FAVESS Co., Ltd., TOYODA KOKI KABUSHIKI KAISHA, KOYO SEIKO CO., LTD.Inventor: Ryuichi Nakamura
