X-Theta-Z Stage for Medical Device Application

Many customers look for systems to test their devices; to do that, they need to operate on multiple axes of motion. While there are many options for linear motion, each customer’s requirements will direct H2W to select a particular technology. A medical device company approached H2W to develop a three-axis ...

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 ...
