The Rexroth Bosch Indramat R911278313 (MHD112C-024-NP0-BN) is a compact, robust motor designed for optimal low-speed torque delivery. The product is IP65-rated, ensuring dust and water resistance, featuring class F insulation in accordance with DIN VDE 0530 part 1. While ideal for operating temperatures between 0-40℃, dust cleaning is recommended to support heat dissipation. With a length of 458mm, a 192mm flange size, and a 130mm centering diameter, the motor delivers a steady 38.0Nm torque for natural convection cooling, and 57.0Nm for surface cooling with a maximum capacity of 148.0Nm. The speed capacity ranges up to 4,000 min-1 at optimal power, with a moment of inertia of 2.73×10-2 kgm2. The motor shaft features a keyway, a DIN 6885-1 key, and shaft sealing rings, excluding holding brake provision. It includes a digital servo feedback and a top-mounted encoder cable outlet, ensuring reliability, maintainability, and efficiency. Shipping is available worldwide, offering a one-year warranty through Indramat USA.
