Customizing a Limited Angle Torque Motor for Drop-in Replacement

A customer approached H2W for a motorized solution for their warehouse sorting machine. The machine's core sorting mechanism incorporated a diverter that rotated approximately fifteen degrees. However, the original drive mechanism had been discontinued, leaving the customer needing a suitable drop-in replacement. Given the limited rotational requirement and the torque ...

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.
