SMAC makes Moving Coil electric actuators. These products are the fastest actuators in the world. Cycle life is well beyond 100M. They have the ability to softly land on surfaces and then apply a programmed specific force. SMAC’s new LDL series of linear actuators has a list price of around $300 making them the first real electric actuator alternative to air cylinders. This price is based on SMAC’s contstent cost down program featuring pointed coils, in-house manufactured encoders, and laser cut parts. SMAC invented the Linear Rotary actuator 25 years ago. These are widely used in Electronic Pick and Place, Quality Thread Check, Bottle Capping, and beginning to find wide use in Automatic Screw Driving and SMART Drilling and Tapping. Interestingly a number of companies are making an effort to copy SMAC - but are not able to match technology or price. SMAC also has stepped up its efforts in inspection by launching the MLA series - a direct challenge to old tech LVDT devices.

SMAC Announces Release of High Torque Brushless Motors

POSTED 09/04/2020

CARLSBAD, CALIFORNIA - SMAC announced the general release of its HT (High Torque) brushless DC motors. The HT basic design is aimed expressly at special OEM applications.

These motors represent a technical Leap over existing DC brushless motor technology:

  • Flux density over 10,000 Gauss - achieved by using Halbach magnet designs (like those used in Particle Accelerators)
  • SMAC’s patent pending PRINTED COIL technology - uses circuit board manufacturing methods to make coils with the following advantages;
  • Very low cost tool up
  • Very quiet because of the near perfect coil layer location
  • Nearly zero variance in resistance
  • Allows the combination of coil/encoder reader head/ controller amplifier all in the same circuit board. (Eliminates wires, soldering, etc.)

The HT motors are available in a 35mm motor (torque as great as 500 mNm) and a 55mm motor (torque as great as 1.0 Nm) sizes as standard with a 7.5mm motor (torque as great as 25 mNm) coming soon. Torques are 2X that of conventional designs.  SMAC also is making special motors for OEM proprietary application - like the HT 100 designed to integrate into a specific customer’s filler line.

SMAC HT motors have much higher torques than the current market leaders and are priced very competitively. Design possibilities exist to reduce motor foot print / weight / and even sometimes eliminate a gear.
