MHD115B-035-PG0-BA

The Bosch Rexroth Indramat MHD115B-035-PG0-BA is a high-performance servo motor in the MHD Synchronous Motors series designed for precision industrial automation. As part of the MHD Series, it delivers reliable rotary motion control for machine tools, printing presses, handling systems and other processing equipment. Its brushless design combined with grease-lubricated ball bearings ensures maintenance-free operation under high radial loads. Supplied with a DIN 42948-compliant flange, the motor integrates directly into servo systems without additional mounting hardware. Featuring a plain shaft design and a multiturn motor encoder, it supports complex positioning tasks with minimal setup.

The motor’s key specifications include a continuous torque at standstill of 50.0 Nm and a Winding Code of 035, which governs its electrical characteristics. At a surface overtemperature of 60 K the MHD115B-035-PG0-BA generates 32.0 Nm output torque with an input current of 21.7 A, while at a winding temperature of 100 K it maintains 36.5 Nm with 25 A draw. The encoder type is digital servo feedback with integrated encoder, offering absolute position detection over 4096 revolutions. Its housing cooling type of natural convection supports passive heat dissipation, and an optional external blower can be fitted for enhanced surface cooling. Additional mechanical dimensions include motor size 115, motor length code B, centering diameter 180 mm, and flange size 192 mm.

Operational performance centers on stiffness and thermal stability. The grease-lubricated ball bearings and shaft seal ensure contamination protection while supporting pinions or belt pulleys on the plain shaft design. The motor’s mass of 30 kg contributes to low vibration in dynamic cycles, and its passive cooling maintains stable winding temperatures under varying loads. Power connections are made via an output connector directed to side B, simplifying cable routing in compact installations. Without an internal holding brake, the motor relies on controlled deceleration profiles managed by the drive to prevent overshoot.

System integration leverages compatibility with digital drive controllers from Bosch Rexroth Indramat, forming a cost-effective automation solution. The multiturn encoder eliminates homing sequences, improving uptime in high-mix manufacturing and continuous processes. Target applications include CNC machining centers, printing and paper equipment, handling machines and other automation platforms requiring precise torque control and rapid response. The MHD115B-035-PG0-BA’s robust design and extensive feature set make it ideal for demanding industrial environments where reliability and accuracy are paramount.
