SMAC Announces Release of High Torque Brushless Motors
SMAC Moving Coil Actuators, Inc. 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.
