Product Description:

The MHD112A-058-PP1-BN is a servo motor produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Engineered for industrial automation, it converts drive current into regulated rotary motion so positioning tables, printing cylinders, or pick-and-place axes reach commanded speed and torque profiles with minimal error. Its compact A-length housing and 112 frame size help it fit dense machine layouts, and the integrated feedback system supports closed-loop control during continuous operation.

This model uses a 130 mm centering diameter to align the motor flange with gearboxes or mounting adapters, while a flange side width of 192 mm distributes mechanical load during operation. The electromagnetic section can produce a standstill torque of 15.0 Nm, so the motor can hold continuous torque at zero speed within its thermal capacity. To support that duty, the stator jacket is prepared for liquid cooling, allowing waste heat to be removed by a closed coolant circuit rather than surrounding air. Position and velocity feedback are delivered through digital servo feedback, which sends incremental and absolute data to the drive for commutation and speed regulation.

A spring-applied brake provides 22.0 Nm of static torque to hold the shaft when power is removed, and the rotor uses a keyed shaft for positive torque transfer to the driven element. For multi-turn position tracking, the encoder provides Absolute (>4096 revolutions) data, so the axis can retain position information through repeated turns. Power conductors exit on side B through an output connector, which helps route cables away from the load side in many machine layouts. A shaft seal helps limit lubricant migration and contaminant entry around the output end. Winding code 058 identifies the electrical matching used with compatible drive amplifiers.
