Product Description:

The MHD112C-058-NP0-BN is a synchronous servo motor developed by Bosch Rexroth Indramat for the MHD Synchronous Motors series. In automated transfer lines, packaging machines, and gantry axes, it converts regulated current from a drive controller into precise rotary motion for closed-loop positioning tasks. The motor is suited for medium- to high-inertia loads, where stable torque delivery and accurate feedback help the axis maintain commanded speed and position during repeated machine cycles. Its integrated design supports direct use in servo systems that need consistent motion control and reliable mechanical coupling.

At standstill, the motor can deliver 38.0 Nm of continuous torque, allowing heavy loads to remain stable without overheating when the axis is stationary. A centering pilot of 130 mm mates the housing with machine frames, and the 192 mm square flange spreads reaction forces over a broad surface to limit bearing stress. Thermal energy created by copper losses is removed by liquid cooling, which helps keep winding temperature within insulation limits during sustained demand. Position feedback is generated by the integrated digital servo feedback (HSF) encoder, providing rotor angle data for commutation, speed control, and accurate positioning.

The motor uses a keyed shaft for positive mechanical coupling, and it includes a shaft seal that helps protect the internal bearings from coolant splash and dust. Power leads are routed to side B through an output connector, which can simplify cable routing on linear axes and other installations with limited space around the housing. Winding code 058 matches the electrical characteristics expected by compatible drive modules sized for the 112 frame. The C-length housing provides extra active stack depth, and the design omits a holding brake, so vertical loads require an external locking device when the motor is not energized.
