Piezo Motion’s novel series of linear and rotary piezoelectric motors represent a quantum leap in design construction of compact ultra-precision, high-performance motor technologies. Manufactured from modern lightweight reinforced engineering thermoplastics, the new range of piezoelectric motors combine superior nanometer precision with fast response at a very economical cost.

Extremely energy efficient, Piezo Motion’s motors consume zero power in hold position while still providing significant force/torque. Available in a variety of configurations including both open-loop control (non-feedback control) and closed-loop control (feedback control) systems, these motors have extremely low voltage compliance (5 to 12 Vdc) and minimal energy demands, enabling miniaturization of associated drive electronics and cost-effective pricing.

Developed and manufactured by Piezo Motion, with custom options available upon request, this new series of rotary and linear motors are rapidly finding use in a growing number of motion control applications.

Linear Motors Features:

Rapid Response Time

At 10 to 30 microseconds for a typical motion response time, the piezomotor is >100X faster than a electromagnetic motor. 

Ultra High Resolution Steps

With <50 nm step resolution the linear piezomotor is capable of an incredible 20,000 steps per mm of travel.

Energy Efficient

With no command signal the piezomotor will hold position with zero power and a force >/= the maximum driving force.

Lightweight

Eliminating copper windings, magnets and ferrous laminations, enables a lightweight construction using engineering polymers.
