Three piezo motor designs for rotary motion

January 7, 2018 By Danielle Collins Leave a Comment

piezo motor

One of the best technologies for achieving extremely small, precise movements is the piezo motor. Based on the piezo actuator – layers or stacks of piezo elements that produce motion through the reverse piezoelectric effect – the piezo motor incorporates mechanical elements to produce strokes of several hundred millimeters or more. And while most piezo motors […]

Which piezo motor types experience wear?

October 5, 2017 By Danielle Collins Leave a Comment

piezo motor

Piezo elements are used in a variety of configurations to provide rotary or linear motion in applications that require short strokes and fast response times. Piezo elements that are used to produce motion through the inverse piezoelectric effect are known as piezo actuators. These devices provide very small displacements with extremely high resolution. When one […]

Why is resonant frequency important in piezo applications?

September 21, 2017 By Danielle Collins Leave a Comment

Resonant Frequency

Resonance occurs when the resonant frequency (also referred to as the natural frequency) of an object or system is equal or very close to the frequency at which it is being excited. This causes the object or system to vibrate strongly and can result in unexpected – and sometimes catastrophic – behavior.  When one oscillating object or system (a […]

FAQ: What are other options for nanopositioning besides piezo actuators?

July 14, 2016 By Danielle Collins Leave a Comment

Nanopositioning—positioning on the scale of one-billionth of a meter—is a common requirement in semiconductor and medical applications, such as metrology, scanning, dispensing, and pumping. But consistently achieving nanometer-level resolution is beyond the scope of most devices that use mechanical rolling or recirculating elements. Case in point: the most common solution for nanopositioning applications is the piezo motor […]

Updated: Trends in electric motors Part IV — More on miniaturization and the special case of medical applications

April 11, 2016 By Lisa Eitel Leave a Comment

There’s a general consensus that the medical industry currently looms largest for innovation in electric motors. That’s what many industry experts we recently interviewed told us. Here, the trend is towards designs that are smaller, lighter, more efficient and cheaper. “The need for portable medical devices is being driven by a more mobile aging population who need machines […]

FAQ: How do linear stepper and linear ultrasonic piezo motors differ?

April 7, 2016 By Danielle Collins Leave a Comment

There are a number of ways in which piezo ceramics can be used to create linear motion, providing any combination of high speed, long travel, and high force. Two common types are linear stepper and linear ultrasonic piezo motors. Both use the inverse piezoelectric effect to activate a rod or pusher and create linear motion, […]

FAQ: Where are linear stepper piezo motors suitable?

March 29, 2016 By Danielle Collins 1 Comment

linear stepper piezomotors

There are several types of piezo motor that provide linear motion, with one of the most widely used being the linear stepper piezo motor. These devices harness the coordinated motion of multiple piezo elements to produce virtually unlimited travel with high resolution and very high stiffness. Construction and operation In the linear stepper design, multiple […]
