摘　　要：设计和制作了一台锯齿波驱动的压电电机,电机直径为28 mm,高56 mm,质量为300 g。在幅值180 V,频率500 Hz的交流电驱动下,电机转速可达89.5 r/min,最大扭矩1 N.mm。电机依靠摩擦力驱动,依靠转子的惯性实现单向输出。该文详细介绍了该电机的驱动原理和结构设计并对电机的一些性能进行了测试。多种测试参数表明,本电机具有工作稳定,运行参数优良的特点。Designing and fabracating a new piezoelectric ceramic motor driven by sawtooth wave is introduced in this paper. Its diameter is about 28 mm,with a height of 56 mm and weight of 300 g. Under 180 V driven voltage and 500 Hz resonant frequency, motor rotational speed can be up to 89.5 r/min, the maximum torque can be up to 1 N · mm. This electrical motor utilizes frictional force to drive the rotor, and achieves the rotating output by the inertia phenomenon. The paper provides the drive mechanism and structural design of this electrical motor, and has tested the performance of the electrical motor. Various kinds of datum show that this electrical motor can work steadily and the operation characteristic is good.
