The MHD115C-058-NG0-AA synchronous servo motor by Bosch Rexroth Indramat represents a high-performance solution within the MHD Synchronous Motors series, engineered for demanding industrial applications. This product type is designed around a plain shaft with shaft seal for robust operation and simple mechanical integration. Featuring a centering diameter of 180 mm and a flange size of 192 mm, the motor ensures compatibility with standard DIN 42948 mounting systems. The unit incorporates a winding code of 058 and an advanced digital servo feedback (HSF) encoder, enabling precise control and repeatable positioning. Weighing approximately 55 kg, the motor is optimized for both performance and ease of handling.



This servo motor delivers a continuous torque at standstill of 70.0 Nm and reaches a theoretical maximum torque of 231 Nm, providing excellent power density. Its electrical characteristics include a torque constant of 0.95 Nm/A, a voltage constant of 86.4 V/1000 min⁻¹ at 20 °C, and a low winding resistance of 0.06 Ω, ensuring efficient energy conversion. The motor supports a peak current rating of 371 A, with a rated frequency of 67 Hz under natural convection cooling and up to 133 Hz with surface cooling. Position detection is handled by a relative encoder, allowing quick startup via stored data memory.



Designed for reliable operation in harsh environments, the motor employs natural convection housing cooling and boasts a thermal time constant of 100 minutes, ensuring stable performance during extended duty cycles. Its plain shaft and integrated shaft seal protect against contaminants, while the robust bearing supports high radial loads and offers a service life of 30,000 operating hours per ISO 281 standards. The flange and centering diameter facilitate direct mounting of belt pulleys or pinions, simplifying mechanical coupling. With no holding brake, the compact design minimizes inertia, enhancing dynamic response and reducing energy consumption during rapid speed changes.



Integration of the MHD115C-058-NG0-AA is streamlined by its output connector power connection directed to side A, improving cable routing in tight assemblies. The motor can be installed in any orientation and supports a maximum elevation of 1,000 m above sea level without performance loss. Ideal for printing, packaging, paper, and food processing machinery, this servo motor offers flexibility and precision in automated manufacturing systems. Its adherence to DIN mounting standards ensures seamless replacement and system upgrades across various industrial drives.
