Comparing Performance and Efficiency of Linear Motors, Ball Screws, and Rack-and-Pinion Drives

Wittenstein educates the market on performance and efficiency of linear systems in this article in the February 4 issue of Machine Design.

Andrew Stock provides further insight into linear system efficiencies. Key points include:

• Rack-and-pinion actuators can have accelerations and speeds nearly as high as those of linear motors.
• Rack-and-pinion drives have efficiencies as high as 97%.
• Efficiency of linear motors is about 85%, and up to about 90% for ball-screw drives.

Learn about the best in linear motion from the leaders in motion control.
