R911278313
The R911278313 (MHD112C-024-NP0-BN), produced by Rexroth Bosch Indramat, is a compact and durable motor designed to deliver a high torque at low speeds. Measuring 458mm in length, this motor has a flange size of 192mm and a centering diameter of 130mm. It features an 'N' type housing that can utilize natural convection or surface cooling for heat dissipation. With an IP65 protection rating, it is secure from dust and water damage and incorporates DIN VDE 0530 part 1 class 'F' insulation. Operating in 0-40℃ environments is recommended, and routine cleaning for dust is suggested to optimize cooling effectiveness.
The functional features of the R911278313 (MHD112C-024-NP0-BN) are remarkable, offering a continuous torque at standstill of 38.0Nm (increases to 57.0Nm with surface cooling) and a maximum torque capacity of 148.0Nm. Running under nominal conditions, the motor generates a torque of 16.6Nm at a speed of 2500min-1, which can enhance up to 44.1Nm using surface cooling. The motor can reach a maximum speed of 4000min-1 at its highest permissible current of 120A. Its 2.73×10-2 kgm2 moment of inertia enables it to accommodate loads with up to 0.273kgm2 moments of inertia. The motor shaft features a DIN 6885-1 standard keyway, sealing rings but lacks a holding brake. Lastly, the R911278313 (MHD112C-024-NP0-BN) uses digital servo feedback for accurate positioning, yielding high reliability and efficiency over its durable lifespan.
