The rotor swimming in fluid isn't in contact with the stator directly. The energy produced by the piezoelectric vibration is transferred from the stator to the rotor through the fluid medium, which rotates the rotor.
液体媒质超声波电机是基于液体媒质的非接触型超声波电机,其定子与转子不直接接触,并且转子浸于液体媒质之中,定子压电振动所产生的能量通过定转子间的液体传递给转子,从而驱动转子旋转。
