New high torque density motor from ThinGap

ThinGap has developed the first member of a new motor family of high performance and extremely high peak torque density brushless PM motors reaching over 20 Nm/kg. The frameless LSI 105 torque motor model is 105 mm OD (4.125 in.) 25.4 mm (1.0 in.) long. Continuous torque reaches over 2 Nm (283 oz-in.) in typical applications.

The ThinGap LS torque motor’s family of zero cogging performance is embedded in a simple frameless configuration. It’s combined with large ID through-bores that allow easy assembly into OEM motion products. The LSI 105 torque motor exhibits low torque ripple (less than -1%) and zero cogging. The efficient potted winding and thermally conductive structure offers superior heat transfer in enclosed places and works well with active cooling systems such as cooling loops or oil filled assemblies. Applications range from peak high torque servo and propulsion systems to lightweight, precision tracking such as beam steering and LIDAR.

Adjusting windings are available that cover common bus voltages and speed requirements. Motor stack lengths, integrated Hall devices and encoders are optionally available.
