Why Do I Need A Voice Coil Stage?

In engineering applications that require a limited range of motion, a voice coil or non-commutated direct current linear actuator is often the preferred choice. The ironless core coil assembly has no magnetic attractive force to the stationary magnet assembly, which reduces the load on the bearing system and increases its life. There are also no magnetic drag forces (hysteresis), which allows for higher accelerations. This type of actuator particularly excels in high-velocity or high-frequency solutions where direct drive is required. Notably, the absence of electrical components, such as Hall Effect sensors, contributes to a more streamlined and reliable system overall.

The Relationship Between Clearance and Thrust in Linear Induction Motors

A linear induction motor has a primary or coil assembly and a secondary or reaction plate. The primary consists of three-phase coils wound and inserted into a steel lamination stack with thermal protection components. At the same time, the secondary or conductive reaction plate includes a combination of a conductive ...

Closed-Loop LSS Series

The Closed-Loop Linear Stepper Stage is a revolutionary new series of single-axis linear stepper stages that integrates a linear encoder into the single-axis linear stepper motor stage to operate the linear stepper motor as a 2-phase brushless linear motor when coupled with a state-of-the-art motion control electronics package provided by ...
