As many products become smaller, manufacturers increasingly require mechanisms able to execute movements that are thousands of times smaller than a millimetre. As a world leader in piezoelectric technology, PiezoMotor, based in Uppsala, Sweden, provides the precise micro and submicro control manufacturers need to improve their products.

"We are becoming involved with more people who come to us saying that they need our solutions," says CEO Johan Westermark. "We have the building blocks for new products."

Used for positioning tiny components with pinpoint accuracy, piezoelectric motors are more accurate than traditional direct current and stepper motors in applications such as optical and medical devices, and semiconductor manufacturing.

"Our company's motto is 'simplicity in motion'," says Anders Larsson, sales and development manager. "With PiezoMotor products, you can simplify your design and continue to improve performance without having to change your motion solution."

Easily adaptable to clients' needs, the company's proprietary Piezo LEGS technology can be used outside the range of typical piezoelectric motor applications.

Named for its several leg-like structures that move a tiny object when voltage is applied, Piezo LEGS is able to lift as much as 50 kilograms with absolute precision.

PiezoMotor's smallest rotary motor, Piezo LEGS LR17, is 17 millimetres in diameter and can hold a position without using any power - reducing cost and energy consumption.

"Our piezomotors may look simple, but they meet many parameters," says marketing manager Olle Lindkvist.

To introduce its technology to more Asian industries, PiezoMotor seeks distribution partners throughout the region. PiezoMotor partnered with North River Corporation in May to distribute its products in Taiwan, where it has a representative office in addition to its representations in Japan, South Korea and Singapore.

PiezoMotor is also present in China through its relationship with miniature and micro-drive technology provider FAULHABER, which has several offices and will distribute PiezoMotor products next year.
