Rotor/stator kits

For many industrial applications, engineers have resorted to available drive motors without optimizing these for the respective application. For many mechatronic drives, such as the axle drives of robots, however, careful selection is a prerequisite to achieve the maximum torque and precision at a minimum weight and minimal power loss. By optimizing all relevant motor parameters while observing the required load profile (concurrent engineering), the researchers at the Institute of Robotics and Mechatronics at the German Aerospace Center (DLR) were able to develop the new “RoboDrive” motor technology. This technology combines high torque development and power density in relation to weight and size. Dimensions such as synchronization, dynamics and thermal connection are aligned to the particularly high demands of robotics. The RoboDrive motors have been manufactured by TQ Systems since 2006. The product spectrum includes standard stators and rotor sleeves as installation sets for the highest possible user-specific integration. Alternatively, the motors can be equipped with hall sensors or magneto-resistive position sensors, depending on the application and requirement profile for speed or motion detection.
