Motors/Actuators

rotary motor and actuators
Our magnetic technology for the motor/VCM market delivers the ability to push the limits on miniaturization, efficiency and performance.

We design motors and actuators with features such as:

  • High force-to-mass ratios
  • High-speed moving coil designs
  • Capability of withstanding harsh environments.

We have extensive experience in designing and producing rotary motors, actuators and voice coil motors. End uses for these devices include semiconductor capital equipment, missile guidance gyros and fin motors, industrial shaker assemblies and factory automation equipment.

DESIGN HELP

When working with our engineering group, you might be asked:

What market is the solution to be used in, such as aerospace, semiconductor or medical?

What are the performance characteristics such as, space and weight constraints, packaging and electrical characteristics?

Our design engineering group along with process and production engineers will quickly move from computer model to prototype right on to production.


MATERIALS

High performance actuator and motor design requires the use of materials that push the limits of material science.  Magnet material selection is critical and we can assist in the selection of the best material.  Tradeoffs in the selection include temperature, residual induction, coercivity and environment.

Typical materials are Alnico, Neodymium Iron Boron and Samarium Cobalt.


FAQS

Can I use Nd-Fe-B magnets at high temperature? Our typical answer is yes, but we don’t like to see this material used beyond about 120 °C.

What is the best material for very harsh corrosive environments? SM-Co is the first choice for high performance in harsh environments. It also is the material of choice for temperatures up to around 300°C. Alnico also is a good choice for this environment although the performance is typically lower than Sm-Co.

Can Dexter build memes devices? Typically, we do not get into the fabrication of memes machines.
