MHD131D-024-NG0-AN

The Bosch Rexroth Indramat MHD131D-024-NG0-AN synchronous motor from the MHD Synchronous Motors series is a high-performance Servo Motor designed for precision automation. This product_type features a 024 winding code and a Digital Motor Encoder (HSF) for reliable feedback. The motor is configured with a plain shaft and without holding brake to simplify integration in dynamic systems. Encased in an IP65 housing, the motor is protected against dust and water ingress for harsh industrial environments. Its robust construction and advanced control capabilities make it an ideal solution for demanding motion control applications.

The MHD131D-024-NG0-AN offers comprehensive technical specifications: a continuous torque at standstill of 160 Nm and a maximum torque of 448 Nm at a maximum speed of 3000 RPM. The motor has 4 pole pairs, a motor size 131, and a flange size of 260 mm with a centering diameter of 250 mm. Its overall weight is 113 kg, with a motor length denoted as “D” to fit standardized drive stations. A shaft seal ensures environmental integrity, while the output connector directs power to side A for streamlined cabling.

Operational performance is adaptable through three cooling methods. In natural cooling mode, the rated speed is 2000 min⁻¹ with rated currents ranging from 8.2 A to 15.2 A and torques between 17.9 Nm and 32.3 Nm, delivering 4.4 kW to 8.3 kW. Surface cooling boosts performance to 14.4 kW, with a rated current of 25.7 A and a rated torque of 56.1 Nm. The liquid-cooled variant achieves up to 20.4 kW of output, 36.7 A rated current, and 80.3 Nm torque, with a time constant of 30 minutes. Natural cooling exhibits a 100-minute thermal time constant, while surface cooling and liquid cooling have 45-minute and 30-minute constants respectively, ensuring predictable thermal behavior.

System integration is simplified by the digital servo feedback encoder and relative position detection, enabling seamless connection to Bosch Rexroth Indramat controllers. The motor’s IP65 protection rating and shaft seal extend operational reliability in dusty or wet conditions. Power connection via an output connector to side A minimizes installation complexity, and the absence of a holding brake reduces mechanical components. The MHD131D-024-NG0-AN is suited for CNC machines, robotic arms, packaging equipment, and other automated systems that require high torque density, precise feedback, and flexible cooling options.
