U Series Frameless Motors

Mosrac U Series frameless inrunner motors provide direct rotary actuation across a wide size range. The catalogue begins with 12 mm and 14 mm units for compact mechanisms and extends to 200 mm motors for higher-torque axes, with windings selected around voltage, rated speed and continuous torque requirements.

The stator-and-rotor kits are integrated into the customer housing and can be paired with Mosrac encoders, reducers and servo modules. Current application material covers humanoid, collaborative and surgical robots alongside industrial automation, medical equipment and direct-drive machinery.
