ThinGap continues to build out its LS Series of slotless motor kits with the latest release, the LSI 152-14. The new LSI 152-14 is a thinner (smaller axial height) motor kit than two existing 152mm OD part sets. The new part has an outer diameter (OD) of 152 mm, and an axial height of just 14 mm, making it the shortest mid-size motor in the ThinGap portfolio. With a total mass of just over 383 grams, it offers a continuous torque output of 1.36 N-m, and peak 1-second torque as high as 15.8 N-m.

Although capable of reaching speeds up to 1,590 RPM, the LSI 152-14 is specifically designed for optical communication terminals, particularly within coarse pointing assemblies—joining other models in the LS Series that address similar applications. Multi-axial gimbal systems across terrestrial, airborne, and space applications can take advantage of high-performance, cogless Ring Motors like ThinGap’s industry-leading LS Series. These low profile motors enable precise direct-drive motion and position control, while delivering substantial savings in Size, Weight, and Power (SWaP).

With a distinguished spaceflight heritage and more than two decades of experience in the design and production of slotless motor kits, including for NASA, ThinGap can leverage proven designs and analytical modeling that results in highly accurate transitions from predicted performance to real-world operation. 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.
