ThinGap is pleased to announce first deliveries of its new TGI 148-66, marking a clean-sheet motor targeted at air-bearing applications within the semiconductor market. The new part set has a rotor diameter (OD) of 148 mm, and an axial height of 66 mm. With a total mass of just over 2.4 kg, it offers a continuous torque output of 10.9 N-m, and peak 1-second torque as high as 80.1 N-m.

The TGI 148-66 highlights the highly flexible architecture of ThinGap’s TG Series. TG Series motors utilize an ironless, toothless stator design, resulting in linear torque constants and exceptionally high peak torque capability for highly dynamic, responsive actuation. The absence of iron eliminates attractive forces between the rotor and stator, a critical advantage in air-bearing applications.  When combined with a near-perfect sinusoidal back-EMF and drive, this design effectively eliminates torque ripple while producing zero cogging and zero radial disturbance forces. Together, these characteristics deliver an ultra-high level of precision, smoothness, and responsiveness—key performance advantages for next-generation semiconductor applications seeking improved accuracy and higher processing throughput.

The TG Series has previously been successfully used in a wide variety of generator, propulsion, and flywheel applications, ranging from gyro-stabilization in marine applications and satellites, to airborne starter-generators. Furthermore, the process steps needed to produce motors of all sizes are highly scalable, with the company shipping motors ranging between 25 mm up to 600 mm in diameter.

Though now part of the greater Allied Motion organization, ThinGap stands atop a proud 25-year history supporting customers in aerospace and other precision industries. The ability to serve such a diverse customer base is due to ThinGap’s heritage and unique capabilities as an organization.

Since 1999, ThinGap has developed hundreds of motor designs, and shipped thousands of motors to customers ranging from NASA to Fortune 500 companies, including more than 3,500 motors actively in space.  One of the key enabling factors is the close integration of production, engineering, and operations within a single location.

ThinGap’s ability to rapidly react to customer needs is reflected in sample quantity products often shipping within a week or less, with a ramp to production volumes in 3-4 months. Additionally, preliminary custom electro-magnetic designs and space-claim CAD models are available in 48 hours, with first deliveries often happening in 9-12 months from project kickoff. Because of ThinGap’s advanced analytical modelling, final designs are promised to be within 95% of prediction performance. Well defined production processes, 3D-printed tooling, refined modeling and analytical tools all contribute to the ability to quickly support customers in a fast paced marketplace.

ThinGap has the capability to take any off-the-shelf motor kit and modify it to the customer’s exact requirements for both its LS and TG Series, such as winding changes, or environmental conditions like space-rating or submergible applications. Modified and custom motor designs address the need for very specific performance specifications, operational requirements, cost optimized solutions, and unique form factors that may be required for a given project.

Additionally, ThinGap has the in-house capability to design and manufacture framed or housed motor assemblies as a pre-integrated solution. Housed and framed assemblies enable more cost-effective, turnkey solutions desired by programs with tight schedules which need to be able to rapidly integrate a motor into a system.
