Motion systems application examples: Linear motors
More than half of all linear motors go into applications for machine tools or the manufacture and assembly of semiconductor components and electronics. It’s no wonder: Linear motors are the precise but generally costly option to which other linear devices are compared. In fact, applications for these relatively new motion components also include those that […]
Chieftek CLS linear-motor stages excel in precision applications
Chieftek Precision Co., Ltd. now sells Compact Linear Stages — CLS modules — for use in precision applications. Compared to traditional ballscrew modules, CLS linear-motor stages use direct driving to output high thrust with superior precision and velocity. They also have a highly integrated mechanical design to boost productivity with better linear-axis reliability. More after […]
Motion systems application examples: Brakes, clutches and torque limiters
Updated November 2018 || By Lisa Eitel • Brakes, clutches and torque limiters serve similar functions in packaging machinery, medical equipment, industrial hoists and installations. Essentially, brakes stop and hold loads while clutches and torque limiters disengage and engage power-transmission outputs to transfer torque from an input. Torque limiters usually modulate power transmission to protect […]
Motion systems application examples: Ballscrew applications from mainstream to extreme
By Miles Budimir • Ballscrews are a tried and true linear motion component. They best suit applications needing light, smooth motion; applications requiring precise positioning; and when heavy loads must be moved. Examples include machine tools, assembly devices, X-Y motion and robotics. Ballscrews are usually classified according to factors such as lead accuracy, axial play and […]
