Target Design Conciliation & Application Review

Target application and engineering staff review key requirements to improve machine performance

Single axis solution

Axis performance requirements:

High speed accurate positioning of a large mass, in high ambient temperature and high vibration. Replicate Joy-Stick control panel functionality. Occasionally used outdoors.

Currently being done with step motor technology. Cannot meet speed requirements.

Product Technology Selected

Primary challenge to move >500 lb mass 1.5” in .5 seconds and maintain +/-.001” accuracy. Ambient temperature can reach 100 Deg C. High vibration induced from 20,000 RPM turbine. Target selected a Danaher AKM motor, NEMA True gear head, Baldors Mint II servo controller and a Maple systems touch screen

Design Implementation

The existing system used a NEMA 34 step motor and drive. The control panel consisted of a Joy- Stick and push buttons. The AKM servo motor with a NEMA 34 mounting and Resolver was a perfect solution to combat the high temp and vibration concerns. A 4:1 NEMA True precision gear head was included to reduce the reflected load inertia and meet the positioning tolerances. The Mint II servo controller and Maple touch screen was an ideal alternative to the existing control panel. The systems were packaged in a NEMA 4 enclosure with water-tight cabling to complete the package.

Overall Success

The design was completed meeting all the application requirements. The machine performance was greatly increased with little impact to the existing package. The motion solution has extended the capability of the overall system opening new markets for it to be used in.
