Multilayer Piezo Actuators Characteristics

Piezoelectric actuators  is a new type of energy conversion mechanism that converts electrical energy into mechanical energy through piezoelectric vibration of a piezoelectric body. The general piezoelectric actuators mainly relies on piezoelectric stator vibration and drives the rotor to rotate or move linearly through friction transmission. Compared with traditional motors, piezoelectric actuatorshave the advantages of small size, large torque, compact structure, low speed, no electromagnetic interference, and self-locking after power failure.
