Miniature Piezo Motors

Miniature Piezo Motors

Johnson Electric provides miniature piezo motors in two platform technologies. The Nanomotion brand EDGE motor series is the smallest industrial motor of its kind available in the marketplace today. Providing unlimited linear or rotary motion, the EDGE motor works with a uniquely designed, compact ASIC-based driver, and can be operated with any servo controller. The EDGE motor operates in a wide dynamic velocity range, has excellent move and settle characteristics and very low power consumption.

The ST series provides high resolution motion control for linear or rotary devices in a fraction of the space of traditional mechanisms. The ST is ideal for small stepping as well as continuous travel, with the ability to make step increments in the tens of nanometers and the ability to operate at speeds up to 250mm/sec. Offering unlimited travel and a wide dynamic velocity range, the ST series is available in medium and low speed versions for high resolution operation.
