Discover piezo precision
At Piezo Motion, we recognize the market's demand to reduce the complexity of products while adding performance and precision. We are displacing traditional DC motor and actuator suppliers in applications that need the benefits of piezo technology at a competitive price.
Rotary Motors
Piezo Motion’s rotary piezo motors represent a quantum leap in design of small size high-performance DC motors. Injection-molded using extremely durable, but light weight engineered reinforced thermoplastics, they combine economical cost with superior precision and ultrafast response/start-stop characteristics.
RAS Series
Affordable, ultra-lightweight (0.1 oz) miniature precision rotary piezoelectric motor. With low voltage: {5V DC} and extremely energy efficient: zero energy consumption in hold position. >200,000 steps per rotation. Rapid response time: 10μs. Hollow shaft and solid shaft options, direct drive with range of torques {>1 mN.m to >4 mN.m}. Open and closed loop configurations available. This product is made in the USA and holds patents accordingly. Made with injection-molded thermoplastics, this precision motor is nonmagnetic. Piezo Motion motors yield high resolution without sacrificing the torque output - holding torque is higher than driving torque with zero power consumption. Operating temperature range -20° to 80° C.
RBS Series
Affordable, lightweight (2.4 oz) compact precision rotary piezoelectric motor. Includes low voltage: {5V DC} and extremely energy efficient: zero energy consumption in hold position. >600,000 steps per rotation. Rapid response time: >30μs. Hollow shaft and solid shaft options, direct drive with range of torques {>30 mN.m to >60 mN.m}. Open and closed loop configurations available. This product is made in the USA and holds patents accordingly. Made with injection-molded thermoplastics, this precision motor is nonmagnetic. Piezo Motion motors yield high resolution without sacrificing the torque output - holding torque is higher than driving torque with zero power consumption. Operating temperature range -20° to 80° C.
Linear Motors
Highly energy efficient, Piezo Motion’s linear motors consume zero power in hold position while still providing significant force. Available as both open-loop control (non-feedback control) and closed-loop control (feedback control) systems, Piezo Motion’s linear motors are offered in a variety of configurations (including non-magnetic).
LAS Series
Affordable, ultra-lightweight (0.1 oz), miniature precision linear piezoelectric actuator that is low voltage: {5V DC} with a 9 mm stroke. Extremely energy efficient with zero energy consumption in hold position. Nanometer level resolution: (<40 nm). Rapid response time: 10μs. Open and closed loop configurations available. Made in the USA. Injection-molded thermoplastics.
LBS Series
Affordable, extremely lightweight (0.8 oz), miniature precision linear piezoelectric actuator. Low voltage: {5V DC} with 9 mm stroke. Energy efficient with zero energy consumption in hold position. Control step of 0.05 microns at full thrust, high hold force motor at 20,000 steps per mm. Nanometer level resolution: (<50 nm). Rapid response time: 20μs. Open and closed loop configurations available. Made in the USA. Injection-molded thermoplastics.
LCS Series
Affordable, very lightweight (1.5 oz) compact precision linear piezoelectric actuator. Low voltage: {5V DC} high force: {4N}, 15 mm stroke. Energy efficient: zero energy consumption in hold position. Nanometer level resolution: (<50 nm). Rapid response time: 20μs to 30μs response compared to a typical stepper motor with 5ms to start motion. Open and closed loop configurations available. Made in the USA. Injection-molded thermoplastics.
Open- or closed-loop
Piezo Motion’s rotary motors are available as both open-loop control (non-feedback control) and closed-loop control (feedback control) systems; and are offered in a variety of configurations (including non-magnetic).
In the closed-loop system, motion control of the piezo motor is achieved via feedback generated from an encoder integrated within the motor assembly. Encoder communication electronics consists of a daughter board (pcb) with a serial (RS-232) port, mounted onto the main driver board.
Optional programmable logic control (PLC) software with graphical user interface (GUI) enables control of the motor using standard Windows OS.
Principle of operation
Piezo Motion Drivers for all our motors
Piezo Motion's electronic driver PCB has been designed to provide an economical user-control interface compatible with all of our motors. Each driver PCB is supplied pre-programmed for the specific motor model and is software configurable to provide optimization of drive signals and integrated controls.
The electronic driver PCB enables precision motion control of the piezo motor via a microcontroller-based 12 V DC digital system, which also allows for user-generated inputs for motion control.
