Product Description:

The MHD112D-024-PP0-BN is a three-phase servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It employs a digital servo feedback unit with an integrated encoder, allowing the drive controller to read absolute rotor position on every cycle for precise closed-loop control. As a servo motor, it converts electrical energy into regulated rotary motion for positioning, indexing, or velocity-regulated tasks in automated machinery that depend on accurate axis synchronization. This type of motor is suited for axes that require repeatable motion during frequent starts, stops, and direction changes.

At standstill, the motor can deliver a continuous torque of 48.0 Nm, enabling it to support substantial static loads without overheating. Mechanical alignment is assisted by a centering diameter of 130 mm, while the square bolt circle is matched to a flange that measures 192 mm across for rigid mounting to gearboxes or machine frames. Heat generated in the stator is extracted through liquid cooling, a housing option that helps maintain winding temperature during extended duty cycles and supports higher power density than air-cooled models. Electrical power is fed through an output connector, and the shaft exits the housing as a keyed design that transfers torque by positive engagement. A shaft seal is present to limit the ingress of coolant or dust into the bearing cavity. The keyed shaft is suitable for couplings or transmission elements that require secure torque transfer without slip.

The power leads exit toward side B of the housing, leaving the feedback connector unobstructed, and the unit is supplied without a holding brake, so external clamping or drive torque must secure axes at rest. The motor is size 112, uses winding code 024, and is built in length class D to provide a balance between inertia and peak torque capability. Position detection is absolute (>4096 revolutions), eliminating the need for homing after power-up and supporting multi-turn tracking in applications that require coordinated motion across complex cycles. This feedback arrangement is useful on machine axes that must retain position information after normal power interruptions.
