Product Description:
The MHD112B-024-PP1-BN is a servo motor in the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. With a size 112 frame and B length, this unit is aimed at medium-to-high inertia axes in packaging machines, gantry drives, and transfer lines. Within such systems, it converts drive current into precise rotary motion while its integrated feedback reports position to the controller for closed-loop control. This arrangement supports accurate starts, stops, and speed changes on coordinated machine axes. It is suited to applications that require repeatable motion under changing load conditions and frequent acceleration.
At standstill, the motor develops a continuous torque of 28.0 Nm, which allows it to hold substantial load without overheating while the shaft remains stationary. Heat generated during this mode is removed by liquid cooling, so the motor can sustain output in enclosed spaces where ambient air movement is limited. Mechanical installation uses a centering diameter of 130 mm and a square flange of 192 mm, which support accurate alignment with mounting faces and gearboxes. Power exits through a connector on side B, and torque is transmitted through a keyed shaft with a shaft seal to support secure coupling and protect the bearing area from contamination. The cooling method also reduces dependence on cabinet airflow around the motor body.
An integrated holding brake rated at 22.0 Nm helps prevent back-driving when power is removed, which is useful on vertical axes and transfer positions that must remain fixed. Rotor position is reported by digital servo feedback with absolute position over 4096 revolutions, allowing the drive to recover shaft position after a power cycle without a homing move. Winding code 024 matches the motor's electrical characteristics to compatible Indramat drive modules for proper current and voltage behavior. This feedback and brake combination supports controlled restarts and stable positioning during interrupted production cycles. Absolute position tracking also helps maintain sequence position in automated lines after controlled stops.
