Evolving Design Challenges with Piezoelectric Motion Devices (Part 1 of 3)

In the world of Motion, Piezoelectricity is a characteristic of certain solid materials whereby electric charge accumulates internally and is released when the material is stressed—was discovered by Jaques and Pierre Curie in 1880. The reverse effect, whereby piezo materials will exhibit a deformation resulting from an applied charge, was deduced by Gabriel Lippman in…

Accurate Motion provided by Piezoelectric Motor Without Gears or Magnets

PRECISE MOTION PROVIDED BY PIEZOELECTRIC MOTOR WITHOUT MAGNETICS AND GEARS

When Engineers hear the word “motor,” they will typically think of “electromagnetic.” Traditional motors use coils and magnetic materials to provide rotary or linear motion. For example, AC or DC motors, brushed or brushless, stepper, or other configurations. The interaction between magnetic fields and materials converts electrical energy into mechanical motion. The alternative to the…

Electronic Driver – Piezo Motors

ELECTRONIC DRIVER – PIEZO MOTORS

As with electromagnetic motors, a complete and useable piezo motor assembly consists of three parts: the electronic drive, the electrical-mechanical transducer (motor) itself, and the output linkage. For electromagnetic motors, the drive function requires sourcing and dipping current into the electromagnetic coils, which is usually done using power semiconductors. These power devices are controlled by…

Piezoelectric Motors- the Better Alternative

piezoelectric motors: the better alternative

Piezoelectric motors have evolved from their beginnings in laboratories to use in mass production industrial applications. Modern piezomotor designs provide a higher level of performance from a smaller size, produce higher resolution movement, and require less power and energy than other types of positioning technologies. Because of this, piezoelectric motors have several advantages over traditional…
