Product Description:

The MHD115B-058-PP0-BA is a servo motor produced by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It converts commanded electrical energy into controlled rotary motion for positioning tasks in industrial automation cells, packaging axes, and material-handling stations. Its size 115 frame and B length place it in the mid-torque range of the series, where accurate velocity and torque control are required for repeatable motion. The motor is well suited for applications that need consistent response during repeated starts, stops, and short positioning moves.

The motor supplies a sustained torque of 50.0 Nm when the rotor is locked, providing strong stall torque for indexing tables and press axes. A flange diameter of 192 mm and a centering pilot of 180 mm align the housing with standard machine interfaces and help keep mounting concentric. Heat is removed through natural convection, so no external blower or liquid circuit is required. Mechanical power is transmitted through a keyed shaft, which supports positive coupling to pulleys, hubs, or similar drive elements. The motor is supplied without a holding brake, so the machine must provide external load retention when power is removed.

For feedback, the integrated encoder uses digital servo feedback and provides absolute position over more than 4096 revolutions. This arrangement supports precise position control and lets the drive retain multi-turn position information during operation. Power conductors terminate on an output connector oriented on side B, which can simplify cable routing when the motor is installed in confined spaces. This orientation can also help keep cables clear of nearby machine members or panel walls. A shaft seal is fitted at the output journal to help limit dust or coolant ingress, and winding code 058 identifies the electrical characteristics required by the connected drive.
