The MHD115C-035-NG1-AN by Bosch Rexroth Indramat is a high-performance MHD Synchronous Motors servo unit designed for advanced industrial applications. This Product Type features a robust Motor Size of 115 and a precise Centering diameter of 180 mm mated to a 192 mm Flange size. Constructed with a compact Motor Length “C” configuration, the unit delivers reliable power and torque in a streamlined package. Equipped with a Winding Code of 035, this motor balances thermal efficiency and electrical performance to meet demanding cycle requirements. Integration of a high-torque holding mechanism ensures immediate load retention when powered down.



This synchronous motor offers exceptional dynamic response through its Continuous Torque at Standstill rating of 70.0 Nm and matching Holding Brake Torque of 70.0 Nm. The internally mounted Encoder Type (Digital servo feedback HSF) works in tandem with a Type of Position Detection system for accurate relative positioning under variable loads. Electrical characteristics include a precise torque constant of 1.31 Nm/A, a winding resistance of 0.12 Ω, and winding inductance of 1.96 mH, enabling fine current control and rapid acceleration. The unit achieves a theoretical peak torque of 231 Nm and reaches a maximum rotational speed of 4500 rpm for high-speed indexing tasks. Engineers can rely on the motor’s integrated Shaft Design (Plain shaft) with Shaft Seal to deliver consistent performance in contaminated or washdown environments.



Operational reliability is enhanced by a dual-mode cooling strategy: the Housing Cooling Type employs liquid cooling for continuous-duty operations at elevated ambient temperatures, supplemented by natural convection when fluid flow is interrupted. The motor exhibits a thermal time constant ranging from 30 to 100 minutes, depending on the cooling regimen, ensuring sustained torque output of 133 Nm at a rated speed of 2000 rpm under liquid-cooled conditions. A precision-rated frequency of 67 Hz optimizes torque bandwidth, while a specified operating range of 0 °C to +40 °C and storage limits between –20 °C to +80 °C safeguard long-term reliability. Weighing 55.8 kg, the unit delivers an excellent weight-to-performance ratio, facilitating lower inertia loads and faster system response.



Seamless integration is provided through its Power Connection Direction to side A and standardized Power Connection Type via an output connector, simplifying cabling and field service access. The motor’s compact footprint and mounting compatibility make it ideal for packaging machinery, robotics, printing presses, and machine tool spindles. With its combination of precise feedback, high continuous torque, and built-in holding brake, the MHD115C-035-NG1-AN adapts readily to multi-axis servo drives and coordinated motion control architectures. System designers will appreciate the motor’s flexibility and repeatable performance in synchronized multi-motor applications.
