Product Description:

The MHD112B-048-PP2-AN is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. As a torque-generation component for closed-loop drive systems, it converts commanded current into rotor motion for positioning and velocity tasks on packaging, printing, and material-handling machinery. The size 112 housing works with a keyed shaft to transmit rotary force to couplings or pulleys, and the integrated digital feedback allows drive controllers to maintain precise synchronization between the load and the automation program.

Rated for a continuous standstill torque of 28.0 Nm, the unit can sustain that output without exceeding the thermal limits of its insulation system. A flange diameter of 192 mm and a centering recess of 130 mm simplify rigid mounting to machine frames while supporting accurate alignment of the optical measurement system. The housing carries a protection rating of IP65, so dust ingress and water jets do not affect the windings or the digital servo feedback encoder. Internal passages support liquid cooling, permitting higher torque density than natural convection designs. Motor length code B balances inertia against installation depth, and the keyed shaft is protected by a fitted shaft seal. Power enters on side A through an output connector, and winding code 048 matches the stator to the drive's current limits. Absolute position data covering more than 4096 revolutions are returned by the integrated encoder.

The holding brake furnishes 32.0 Nm of static torque so vertical axes remain fixed during power loss. Closed-loop accuracy is within ± 0.5 angular minutes, supported by optical position detection. The specified operating temperature range is 0 to 40 °C, while the maximum installation height is 1000 m above mean sea level before derating applies. Insulation class F supports the winding system, and the shaft seal helps keep contaminants away from internal parts.
