The Challenge

A high precision, portable, laser-based scanning system was being designed by an industrial metrology equipment manufacturer. It featured a scan mirror rotating rapidly in one axis and spinning gradually in another to map out a high-resolution topographical dataset. In order to attain their goals of system portability and capture highly accurate and precise data, the manufacturer required motors and encoders that were compact, light weight, and could offer very smooth position and velocity control.

The Solution

The compact Mercury 1540P digital incremental encoder with a custom flex cable was combined with a 57 mm diameter grating disk to offer 19 µrad resolution feedbacks in a low profile and low-cost solution. The total height of the encoder is just 10.2 mm and it weighs about 14 g. Furthermore, a 43 mm diameter frameless Omni Series motor was integrated into the device reducing their earlier bulky motor stack height to as low as 6 mm and providing the smoothest motion possible from direct drive motors.

The Benefit

Celera Motion’s Omni Series frameless motor technologies and compact Mercury Series encoder were tailored to suit the customer’s exact performance and dimensional requirements. These products were combined to give the customer the portability, speed, and precision demanded by their design.
