MHD112B-058-PP1-BN

The Bosch Rexroth Indramat MHD112B-058-PP1-BN synchronous motor from the MHD Synchronous Motors series is a high-performance, brushless permanent magnet device engineered for precision industrial applications. This motor features a robust liquid cooling system and an integrated multiturn feedback mechanism to ensure maintenance-free operation and reliable performance under continuous duty. Equipped with a With holding brake for secure load holding and a keyed shaft design for positive torque transmission, it delivers dependable kinetic energy in demanding environments. The compact Motor Size of 112 combined with a flange built to DIN 42948 standards enables straightforward integration into automated machinery and process lines.

The motor’s construction incorporates critical design parameters, including a Centering diameter of 130 mm and Flange size of 192 mm for precise mounting alignment. It utilizes a Digital servo feedback w/ integrated encoder capable of Absolute (>4096 revolutions) position detection, ensuring accurate motion control throughout extended cycles. The Winding Code of 058 specifies the optimized coil configuration for efficient electromagnetic conversion. Power is delivered through an Output Connector oriented to side B, while the housing employs Liquid cooling to maintain optimal thermal conditions. The device also features a Shaft Seal to protect internal components against contaminants and maintain long-term reliability.

Operational performance of the MHD112B-058-PP1-BN is characterized by a Continuous Torque at Standstill of 28.0 Nm and a holding brake capable of exerting Holding Brake Torque of 22.0 Nm to secure loads during power-off or emergency stop sequences. Under rated conditions, the motor draws approximately 61 A of input current to deliver an output torque of 42 Nm at speeds up to 4000 rpm, supporting rapid acceleration and deceleration profiles. The keyed shaft design guarantees positive coupling to driven components, while the liquid cooling system stabilizes winding temperatures, reducing thermal drift over prolonged operation. Integrated feedback and position detection simplify tuning, enabling quick commissioning and repeatable motion trajectories.

System integration is streamlined through compatibility with standard servo drives, leveraging the motor’s multiturn encoder for closed-loop control and high-resolution position feedback. The flange and centering diameter conform to industry norms, facilitating direct replacement or retrofit into existing installations without extensive mechanical adaptation. Targeted applications include high-precision assembly systems, CNC machine tools, robotics, and packaging equipment where reliable static torque and dynamic responsiveness are paramount. The Bosch Rexroth Indramat MHD112B-058-PP1-BN motor offers a balanced combination of power density, thermal management, and advanced encoder technology for next-generation automated platforms.
