ThinGap LS Brushless PM Motors Achieve Continuous Torque over 2Nm

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 105mm OD (4.125 inches) 25.4mm (1.0 inch) long. Continuous torque reaches over 2Nm (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 is combined with very large ID through-bores that allow easy assembly into OEM motion products. The LSI 105 torque motor exhibits very low torque ripple (less than -1 percent) 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.
