Product Description:

The MHD112B-048-NP1-AN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It supplies rotary motion to automated axes by pairing a keyed shaft with digital servo feedback (HSF) that tracks rotor angle optically and sends relative position data to the drive. This arrangement supports closed-loop speed and position control in handling, transfer, and indexing applications. The optical feedback system lets the drive correct speed deviations quickly as the load changes. The motor has frame size 112, frame length B, and winding code 048. Power exits on side A through an output connector, which helps keep cable routing orderly in compact machine layouts.

At the mechanical interface, the motor presents a 130 mm centering diameter, which helps seat the flange accurately on the mounting surface. Continuous stall capability is 28.0 Nm, and heat is removed through liquid cooling, so the motor can sustain torque during prolonged low-speed duty. An integral brake holds the shaft with 22.0 Nm when the drive is de-energized, which is useful on vertical axes and other load-bearing positions. The enclosure has an IP65 rating that helps keep dust and water jets away from internal components. A keyed shaft also provides a positive mechanical connection for couplings or transmission elements.

Closed-loop accuracy reaches ± 0.5 angular minutes, allowing fine positioning across an ambient range of 0 to 40 °C. That level of feedback accuracy is useful for short indexing moves and repeatable settling at target positions. Class F insulation supports the winding temperature range associated with servo duty, and the mounting face uses a standardized 192 mm flange pattern for straightforward alignment with machine adapters or gear reducers. A shaft seal is fitted to help prevent coolant or oil from migrating along the shaft during washdown or nearby fluid exposure. The unit may be stored between -20 and +80 °C and installed up to 1000 m above mean sea level without derating.
