Linear Servo Motor At Tech Show

Visitors to the International Manufacturing Technology Show (Sept. 9-15, booth 4104) will be able to see a linear motor made for high-force applications. The design is intended to replace ball-screw drives and enable higher performance and better dynamic accuracy, explains GE Fanuc Automation North America Inc., Charlottesville, Va. With the elimination of mechanical linkages, linear motor drives can have much higher gain factors and provide less servo lag, it adds. The implications are in higher net part tolerances and finer surface finish. That can eliminate, in most cases, secondary operations such as hand polishing, according to the company.
