SMAC Moving Coil Actuators

SMAC is a leading manufacturer of precision programmable electric actuators based on moving coil technology. Our actuators are unique in that force, position, and speed are totally programmable. SMAC electric actuators are designed to perform at exceptionally high speeds or very low speeds and with sub-micron accuracy and repeatability. Patented Soft-Land™ function gives extremely accurate sensing of product location or dimensions.

SMAC also manufactures custom linear and rotary encoders in New Hampshire, USA. Delivery times are within weeks. SMAC encoders are made using optical components provided by large volume manufacturers of printers, cameras, cell phones and independent manufacturers of standard mixed signal ASIC semiconductor products used in optical encoders around the world. We use these high reliability optical components that are made in the millions per year to take advantage of the latest manufacturing technologies used in these fields and the latest design features patented by these suppliers. Technologies include using Interlaced Photo Detector Arrays to better balance the light viewed across the photo sensor array and average imperfections in the code pattern of the scale, LED light intensity auto gain to compensate for LED aging and temperature changes and GUI control of the many features selected in the interpolator and signal conditioning ASIC. SMAC has used over 100,000 of their internally designed encoders in their products. They have been able to discover many of the "User Issues" first hand, that would not be normally seen by a manufacturer of encoders and correct these issue in their products quickly.​

High torque motors are another component manufactured by SMAC. Compared to other brushless motors, the HT Motor has a flat torque–speed curve meaning that the speed is less influenced when the torque is increased. The secret to that is found how the magnetic circuit is built. A combination of SMAC’s patent pending Halbach magnets and printed coil technology achieves higher torque/amp.
