中文摘要：
提出一种基于叠层型压电陶瓷的新型压电直线电机，该电机工作在非共振状态，采用双驱动足设计，在四路相位差90°的正弦波信号激励下，两驱动足分别产生椭圆运动推动直线导轨做直线运动。与共振型压电直线电机相比，该电机具有工作频率可调，工作状态受外界影响小的优点。实验表明，在一定频率范围内，电机运行速度与驱动信号频率成正比。电机最大输出推力为4．1N，最大运行速度为3．7mm／s。
英文摘要：
A new type of piezoelectric linear motor using piezoelectric stack was proposed herein. It operated on non--resonant vibration and used double driving feet. Driven by four sine wave signals with the same frequency and phase difference of 90°, the two driving feet moved along the elliptical trajectory alternately and pushed the slider running linearly. Compared with piezoelectric motors which were based on resonant vibration, it possessed following advantages： its working state is stable under the interference of external factors and the operating frequency is adjustable. The experimental results show that within a certain range of frequency the speed of the motor is proportional to the operating frequency. The maximum thrust force of the motor is 4.1N and the maximum velocity is 3.7mm/s.
