该马达以压电元件所产生的超声波振动,作为转子的驱动源.图1示出:表面波型马达的基本原理.它是以弹性体(E)与固定在这一表面压电元件(V),以及相等于一般马达中,转子运动体(M)三者相互组成.
The motor uses the ultrasonic vibration generated by the piezoelectric element as the driving source of the rotor. Fig. 1 shows the basic principle of a surface wave type motor in which an elastic body (E) and a piezoelectric element ), And equivalent to the general motor, the rotor moving body (M) of the three components.
