MHD112B-048-PP0-AN

MHD112B-048-PP0-AN is a Bosch Rexroth Indramat servo motor in the MHD Synchronous Motors series. The motor is size 112 with length B and winding code 048. It delivers 28.0 Nm of continuous torque at standstill. Its natural-convection housing dissipates heat without forced-air cooling, and the operating ambient temperature range is 0 to 40ºC. The storage temperature range is -20 to +80ºC, and the maximum setup height is 1,000 m above mean sea level. Class F insulation provides the motor’s thermal insulation rating, while IP65 protection guards against dust and water jets.

The motor uses digital servo feedback with an integrated encoder to provide position data to the drive controller. Position is measured optically, with a system accuracy of ±0.5 angular minutes. Absolute position detection covers more than 4,096 revolutions, allowing position information to be tracked across multiple shaft rotations. The keyed shaft supports torque transfer through a key connection, and a shaft seal is installed to protect the shaft entry point. The motor does not include a holding brake.

The flange measures 192 mm, and the centering diameter is 130 mm for mechanical alignment during mounting. Electrical power is supplied through an output connector, with the power connection directed toward side A.
