ThinGap
"Innovation in Motors"
Camarillo, CA maker of zero-cogging slotless frameless motor kits (TG, LS, LSO) for gimbals, precision robotics and space; an Allient company since 2022.
ThinGap is a US designer and manufacturer of slotless brushless motor kits based in Camarillo, California. A motor kit is a frameless rotor and stator set that the customer builds directly into its own mechanism, without a housing, shaft or bearings from the motor supplier. This is the format used for direct-drive joints, gimbals and other compact actuators. ThinGap says it has operated for more than twenty years. Engineering, production and operations sit at a single site at 4035 Via Pescador, and the motors are made in the USA. The company supplies standard in-stock models and custom-made or modified designs, and its main customers are OEMs and government agencies that design their own end systems.
Technology. ThinGap's stators use thin, ironless coils with no slots, paired with an optimised permanent-magnet rotor. Because there are no slots or teeth for the magnets to lock onto, the motors have zero cogging and very low torque ripple. This matters wherever smooth, precise low-speed motion is needed, such as pointing systems, haptic devices and robot joints. The company also highlights a high torque-to-weight ratio, a large central aperture for cables, optics or shafts, and a low axial profile, alongside its proprietary modelling and process capabilities.
Product lines. ThinGap publishes three main robot-relevant motor families:
- TG Series: its original lightweight, high-speed slotless kit, with outer diameters of 57 to 190 mm, continuous torque of 0.74 to 9.46 N-m and continuous speeds of 6,000 to 30,600 rpm. Listed uses are satellite reaction wheels, pumps, haptic robotics and haptic feedback systems, and in some cases propulsion and generator systems.
- LS Series: a lower-speed, high-precision torque-motor line of more than 20 models, with outer diameters of 25 to 267 mm, continuous torque of 0.016 to 11.5 N-m and continuous speeds of 1,530 to 6,370 rpm. The kits have a large through hole and low torque ripple, and an outer lamination stack on the stator helps with cooling. The in-runner models carry the LSI prefix. ThinGap lists gimbals, optics and precision robotics as applications. Smaller 39 mm LS kits were added later.
- LSO Series: outrunner versions of the LS line, launched in September 2021 with the LSO 225-51 and LSO 225-66. Both are 225 mm in diameter. The LSO 225-66 has 17.86 N-m continuous torque and a motor constant of 1.315 N-m/sqrt(W). The LSO 225-51 part set weighs 2.4 kg and has a 198 mm through hole, about 88% of its outer diameter. They suit mechanisms where an outer ring turns around a fixed centre.
ThinGap also makes a TGR line of motor kits designed for satellite reaction-wheel assemblies. It covers five models, such as the TGR 29-12 and TGR 89-26, with continuous torque of 0.014 to 0.745 N-m in atmosphere and speeds of up to 16,000 rpm. Options and custom or modified windings and form factors are offered across the range.
Markets. ThinGap groups its business into medical, industrial and emerging segments. The acquisition announcement named aerospace, defence and medical as its key markets. Robotics appears in its own application lists as haptic robotics and precision robotics. RobotToday lists it as a frameless-motor source for robot joints and actuators.
Ownership. In May 2022 ThinGap was acquired by Allied Motion Technologies Inc. of Amherst, New York, then traded on Nasdaq as AMOT. Financial terms were not disclosed. Allied Motion has since been renamed Allient Inc., and ThinGap now operates as an Allient brand; the ThinGap website footer links to allient.com.
