Product Description:

The MHD112B-024-PG0-BN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as a rotary actuator that delivers closed-loop axis control in automated presses, loaders, and transfer systems. An integrated digital encoder streams position data to the drive so controllers can synchronize motion with millisecond accuracy, making the unit a precise link between electrical commands and mechanical output. This feedback arrangement supports accurate coordination of speed, torque, and shaft position during repetitive machine cycles.

At standstill, the motor can sustain a torque of 28.0 Nm, allowing it to hold loads without stalling during dwell periods. The motor has a flange diameter of 192 mm, which provides the interface to gearboxes or machine frames and aligns the stator concentrically with the driven mechanics. Heat generated in the stator windings is removed through liquid cooling; circulation through the housing maintains a stable temperature profile and supports continuous duty in high-power cycles. The winding code 024 identifies the electrical characteristics that must match the drive for proper current regulation. For feedback, the unit offers absolute (>4096 revolutions) position detection, so homing routines are unnecessary after power loss and multi-turn data remain valid across cycles. The assembly is supplied without a holding brake, so static locking must be provided by an external clamp or by drive torque when required.

Mechanical fitment begins with a centering pilot of 130 mm, which seats the housing precisely in the machine bore and helps minimize runout. A plain shaft transmits torque without keyways, suiting shrink-fit or collet couplings where backlash must be minimized. Power leads exit toward side B, facilitating cable routing where space on the opposite face is limited. Electrical connection is made through an output connector, allowing quick disconnection when the motor is removed from the machine. A shaft seal is present to block coolant ingress, and liquid passageways in the stator jacket complete the closed hydraulic path.
