R911258393
The R911258393 (MDD112C-N-030-R2M-130GA0) is an MDD servo motor manufactured by Bosch Rexroth Indramat, an entity renowned for their high-performance industrial parts. These motor series are marked by their variable continuous torques and speeds making them a reliable choice for various applications in tool making, textiles, packaging machines, robotics, and handling equipment. Their lower inertia, in tandem with permanent magnets, provide high contouring accuracy at elevated feed rates, especially in high-speed cutting tasks. The inclusion of a brushless motor design and lifetime-lubricated bearings make for a maintenance-free operation. Overtemperature protection is ensured by a heating sensor located on the windings, which prevents overload-induced damage.
MDD112 series motors, like the R911258393 (MDD112C-N-030-R2M-130GA0), are designed for shouldering both convection cooling and surface cooling. The motors have an output shaft, available either as a plain shaft for non-positive shaft-hub connections or a shaft with a keyway for form-fitting shaft-hub connections. The R911258393 (MDD112C-N-030-R2M-130GA0) model uses a plain shaft with a built-in seal to block the entrance of any liquids into the motor housing. The motor has direct connections for power and motor feedback cables through its flanged sockets. Its high protection category (IP65) is attributed to the sealing on shaft and cable connectors and it comes equipped with a multiturn encoder. The nominal speed rating is 3000 RPM and 130 millimeters is the centering diameter.
