【Abstract】 In this paper, the operational principle of the cylinder-sphere ultrasonic motor with multi-degree of freedom is presented. Some critical criterion for the motor design are outlined so as to realize its proper motion and improve its work properties. The effect of some factors on the operational properties is analyzed, these factors include mode of vibration, operating frequency, excitation amplitude, location of piezoelectric ceramic, location of support plate, pre-pressure between the stator and the rotor, interfering modes, etc. The methods for satisfying the design requirements are suggested.更多还原
