R911254831
The R911254831 (MDD112D-N-015-N2L-130PB0) is a MDD synchronous servo motor developed by Bosch Rexroth Indramat, known for its synchronicity with the input current frequency. Unique features of MDD motors include integrated temperature supervision which automatically cuts off if the winding temperature exceeds the pre-established threshold. The brushless design and lifetime lubricated bearings promote maintenance-free motor usage. This motor upholds an IP65 protection rating due to its sealed housing and connectors, asserting its high reliability even under adverse environmental conditions. The motor features both convection and surface cooling mechanisms. While convection cooling maintains operation at lower output torque, surface cooling can enhance output torque, albeit, requiring additional installation of a cooling fan.
The R911254831 (MDD112D-N-015-N2L-130PB0) operates at its peak performance when ambient temperature is between 0-45 degrees Celsius. It possesses a shaft furnished with a keyway and supports digital servo feedback, delivering a rated speed of 1500 RPM. Although there is an option to order with a blocking brake, this motor variant does not include it. The power connection is positioned on side B with a motor centering diameter of 130 mm. It is crucial to ensure professional installation to avoid errors. Any modifications to the motor's hardware or software aren't allowed, and only Bosch-recommended accessories should be used with the MDD motors.
