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.

Motor Benefits & Features

Key features and benefits of piezoelectric motors compared to traditional electromagnetic motors

  • High Performance

    Technology that provides >1000 X’s Better Resolution, >100 X’s Faster Reaction Time and >10X’s Greater Specific Power Stall Torque/Force compared to conventional DC motors.

  • Energy & Cost Saving

    Piezo Motion’s piezo motors operate at low voltage (e.g. 12 VDC, customizable down to 5 VDC) and have increased energy efficiency. They are designed for direct-drive applications where the need for a gearhead is eliminated altogether.

  • Unique properties

    Piezo Motion’s piezo motors are scalable in design (rotary and linear), can be operated silently and consume zero energy in hold position.

  • Non-magnetic

    Piezo Motion’s piezo motors are available in non-magnetic configurations making them ideal for specialized applications where traditional DC motors cannot be used (e.g. medical MRI)

  • Low Cost

    Modern engineered thermoplastic design enables Piezo Motion’s piezo motors to be priced extremely competitively compared to other brands and technologies. Simplified driver electronics lowers ownership cost further.

  • Environmental

    Piezo Motion’s piezo motors are immune from electromagnetic interference (EMI /RFI) and do not contain any rare earth elements (REE’s).

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

Watch the principle of piezo motor operation in uni-directional and bidirectional modes

Piezo Motion’s rotary piezomotors work on a patented principle of excitation of ultrasonic standing waves within a piezoelectric resonator.

The resulting superposition of two orthogonal ultrasonic waves causes elliptical movement of the resonator tip which drives the rotor. Piezo Motion’s electronic drivers have been designed to provide an economical user-control interface.

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.
