摘要： In a vibration wave motor wherein a member provided with a composite resin layer providing a contact surface with respect to a vibration member for generating a travelling vibration wave is brought into pressure contact with the vibration member, whereby the vibration member and the member pressure-contacting therewith are moved relative to each other by friction driving with the aid of the travelling vibration wave generated in the vibration member, the composite resin layer is formed of a composite resin composed of a thermosetting resin, for example, an aromatic polyimide resin, as a base material, and a friction regulating agent and, if required, a non-fiber type wear resistance improving agent blended with the base material.

摘要： A vibration driven motor of a construction in which the hardness of the sliding surface of a vibration member is lower than the hardness of the sliding contact portion of a member brought into pressure contact therewith, and the lateral width of the sliding contact portion of the vibration member is smaller than the width of the sliding contact portion of the member brought into pressure contact therewith, whereby the sliding member of the vibration member is caused to wear more than the sliding member of the member brought into pressure contact therewith, thereby to facilitate the discharge of the wear powder thereof and to eliminate the level difference wear of the movable member attributable to the comb-shaped projections and the deterioration of the planarity of the movable member similar thereto. Also, this structure prevents deterioration of accuracy in motor performance when a stopping or starting operation occurs at the same location, or when operating at extremely low speed control is effected, and abnormal wear of the sliding surface of the vibration member is prevented.
摘要翻译：一种振动驱动电动机，其特征在于，振动部件的滑动面的硬度低于与其成为压力接触的部件的滑动接触部的硬度，振动的滑动接触部的横向宽度构件比与其压接的构件的滑动接触部分的宽度小，由此使振动构件的滑动构件比与构件压力接触的构件的滑动构件更磨损，从而便于排出其磨损粉末，并且消除归因于梳形突起的可动构件的水平差磨损以及类似于其的可移动构件的平面度的劣化。此外，该结构防止在同一位置发生停止或起动操作时，或者以极低速度控制进行操作时电机性能的精度降低，并且防止振动构件的滑动面的异常磨损。

摘要： Provided herein is an ultrasonic motor in which at least fluorocarbon polymer is present on the contact surface of at least either of the rotor or the stator. Since the fluorocarbon polymer provides a smooth contact surface, the ultrasonic motor generates no noise and produces a stable starting torque and holding torque. In addition, it has a long life with a minimum of wear.

摘要： A piezoelectric motor achieves maximum mechanical performance, high safety of operation and low costs with a negligible exciting voltage. The piezoelectric engine has a stator whose oscillator designed as a closed waveguide is provided with at least one generator of an elastic travelling wave for the waveguide. A rotor is frictionally engaged by a functional surface of the oscillator. The elastic travelling wave generator is as long as the generated wavelength and consists of a base generator and two supplementary generators that generate elastic longitudinal stationary waves having the same amplitude and wavelength. The stationary waves are offset with respect to the wave generated by the base generator by ± 1/3 of the wavelength along the waveguide. Exciting sources are associated with the base generator and the supplementary generators. The supplementary generators and their exciting sources are designed in such a way that the stationary waves they generate are phase shifted by ± 2/3 π with respect to the stationary wave generated by the base generator. The length of the waveguide is the same as the wavelength of the stationary wave or is an integral multiple thereof.
