Advances in linear motors and hybrid actuators are pushing motion systems toward higher precision, speed and efficiency. A ...

How linear, rotary, reciprocating and oscillating motion are evolving as customization grows and new capabilities emerge.

Abstract: In this paper, a novel variable stiffness mechanism (VSM) based on specially designed S-springs made from shape memory alloy (SMA) is developed. Based on the stiffness model, by changing the ...

Abstract: To provide faster speed response, better current characteristics, more stable suspension, and stronger disturbance immunity for a bearingless induction motor (BIM) system, an enhanced linear ...

Here is how to implement a stepper motor to sense position and actively correct any error that might accrue during actuation.
