Nanomotion ER Motors in Action

The Nanomotion family of ER motors have been successfully applied to applications in defense applications for optics positioning, filter changers and shutters. The ER15 motor, 15mm diameter, is configured with internal piezo elements and offered with a 4096 cpr rotary encoder or adaptable to external encoders.

Particularly in shutters and filter changers that have used bi-stable solenoids or bi-stable dc motors, the ER15 does not suffer from a current surge to overcome the static holding, making it significantly more power efficient and extending battery life.

In addition to defense applications the ER15 is well suited to applications in Semiconductor and Medical equipment where traditional permanent magnet rotary motors are not suitable due to gearing and noise.

A linear assembly used for positioning an optical device is mounted to a portable mechanism and must hold position under 30g’s of vibration. Using a rotational version of a Nanomotion motor, coupled to a screw, we provide significant weight reduction and the ability to function under high vibration while holding position.

Nanomotion 5 Axis Stack – Multi-axis Motion System

This is a 5 axis stage platform consisting from bottom to top, Tip Tilt X Y Z. Nanomotion offers multi-axis motion systems that operate at 5nm encoders resolving moves down to 20nm in step size.

The motion system is also supported with Nanomotion’s AB2 amplifiers, which provide operation in a normal servo mode as well as an ultra-high resolution DC mode, allowing for positioning and motion down to 1 encoder count (5nm). The AB2 supports seamless switching between the two modes for ‘coarse & fine’ motion build into the same axis.

This clip is an illustration of the working principle behind Nanomotion’s patented Piezoelectric servo motors. Watch how the piezoelectric elements “dances”, causing motion due to friction between the element tip and the stage platform.

Nanomotion Stabilizing Stage

An OIS XY platform consists of Nanomotion’s Edge motors on each axis, with a closed loop, position sensor and all of the drive electronics. The controller takes input signals from an external gyro and commands the axes for position stabilization
