摘　　要：介绍了一种微型直线压电电动机,其结构尺寸为2.8×2.8×6 mm,定位精度可达亚微米级,在数码设备、医疗和精密工业等领域存在着广泛的应用前景,但是驱动该电动机需配备专用的驱动电路。通过分析电动机特殊的运动机理并基于其工作原理提出了以NSD2101驱动专用集成电路和C8051F300微程序控制器为核心器件的驱动控制方案。搭建的硬件电路产生了两路相差90°的50 kHz方波信号,顺利地驱动了电动机的运转。A type of micro piezoelectric linear motor is introduced in this paper. Its structure size is 2.8x2.8x6mm and its precision comes up to one-half micron. It can be widely used in digital device,medical facilities and precise industry etc., but this type of mo- tors need to be equipped with the specific driver circuit.Its special movement mechanism is analyzed and a scheme that NSD210] ASIC（ Application Specific Integrated Circuit）and C8051F300 MCU（ Micro programmed Control Unit）are used as the core devices to drive and control the motors is proposed based on the mechanism. Two-phase square wave signals of 50KHz with 90 degree phase shift are generated by the circuit to drive the motor successfully.
