Piezoelectric motors

A piezo motor is based on the change in mechanical shape of a piezoelectric material when an tension is applied.

The material produces ultrasonic or acoustic vibrations and produces a linear or rotary motion.

A few design exists currently:

  • Locking mechanisms
  • Stepping Actions
  • Single Action

    With a fast response of the material (up to 5Mhz), it is possible to obtain a linear speed of 800mm/second.

    According to manufacturers, precision can be of a few nanometers.
