Description

RDrive 70 is a high torque density servomotor based on a super compact frameless motor, custom strain-wave gear, magnetic encoders with absolute position alongside a controller. All those integrated in a single housing.

We have built RDrive servos with quality in mind, using top-grade materials (e.g., rare-earth magnets, electrotechnical steel). The brushless motor, controller, and encoders are of our own design, so the manufacturing process—from welding the stator plates to assembling components into a housing—remains under our control for the majority of our components.
