Product Description:

The MHD112B-048-PG2-AN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed for closed-loop drive systems, the unit converts drive current into controlled rotational motion that positions machine axes with high repeatability. The 112 frame size and B-length housing place it in the mid-power range used in material-handling gantries, packaging equipment, and assembly lines where rapid acceleration and precise stopping are required in compact machine layouts.

Performance is anchored by a continuous standstill torque of 28.0 Nm, allowing the motor to hold loads without overheating while the control loop is idle. Position feedback is supplied through a digital servo encoder with absolute detection over more than 4096 revolutions, and the feedback system uses optical scanning for low jitter. Motion commands are reproduced with a system accuracy of ± 0.5 angular minutes. Thermal energy is removed through liquid cooling, so rated output can be sustained even when the IP65 housing is installed in tight enclosures. The flange measures 192 mm, and the motor uses winding code 048 with a size 112 stator and B-length housing. Power enters from side A through an output connector, and the motor has a plain shaft for use with keyed or clamped couplings.

The mechanical holding brake supplies 32.0 Nm of static torque, maintaining axis position during power loss or when the servo is disabled. Stator insulation is rated F, supporting winding temperatures suited to extended duty within an operating ambient range of 0 to 40 °C and storage temperatures from -20 to 80 °C. A centering diameter of 130 mm helps align the motor concentrically with ISO flanges, and a shaft seal is fitted to resist coolant entry at the motor nose. The assembly can be installed up to 1000 m above mean sea level without derating, and all conductors are routed through the output connector for simpler cabinet wiring.
