    摘要: A claw pole type synchronous motor has two cylindrical stator assembles arranged back-to-back and a magnetized rotor provided coaxially with the stator assemblies. The rotor has a length larger than the total thickness of the stator assemblies and always covers the inner peripheral surfaces of the stator assemblies so as to reduce vibration due to axial movements of the rotor with respect to the stator assemblies. The motor also has an electrical phase angle defined between the center lines of the corresponding claw poles of the adjacent stator assemblies made equal to the theoretical electrical phase angle minus an electrical angel within a range more than 0.degree. and less than 10.degree..
