SMAC Announces Release of High Torque Brushless Motors
SMAC Moving Coil Actuators announces new brushless high torque DC motors.
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 12.5 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.

The ERT150 - Dorner's Next Evolution of Edge Roller Technology Conveyors
The next evolution in Dorner's Edge Roller Technology conveyor platform, the ERT®150, is ideal for small and light-load assembly automation, as well as medical and medical-device assembly application. The ERT platform is the only pallet conveyor of its kind available with an ISO Standard Class 4 rating for cleanroom applications. Earning the ISO Standard 14644-1 Class 4 rating means Dorner's ERT150 will conform and not contribute to the contamination of cleanrooms to those standards. As implied by its name, the ERT150 (Edge Roller Technology) uses rollers to move pallets through the conveyor smoothly with no friction (a byproduct often seen in belt-driven platforms). The conveyor's open design eliminates concerns of small parts or screws dropping into rollers and causing conveyor damage or jamming. The ERT150 is suited to operate in cleanroom environments requiring a pallet handling conveyor. It is capable of zoning for no or low-back pressure accumulation and is ideal for automation assembly applications within industries including medical devices, electronics, consumer goods among others.
