Product Description:
The MHD112D-024-NG3-BN is a servo motor built by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. It is intended for industrial automation where precise torque and velocity regulation are needed to drive gantries, tooling spindles, or packaging axes. By pairing with a compatible drive controller, the motor converts stator power into regulated shaft rotation, allowing closed-loop positioning tasks across continuous production shifts.
Mechanical mounting is simplified by a centering diameter of 130 mm and a square flange that measures 192 mm across, giving the frame enough surface to distribute reaction forces into the machine bed. The motor can deliver a continuous standstill torque of 48.0 Nm, so holding position at zero speed does not overheat the windings when the axis is locked. Stator losses are removed through liquid cooling passages molded into the housing, letting the unit maintain rated output even in tight cabinets. Electrical terminations are routed to side B, preventing cable congestion on adjacent components. A shaft seal is fitted to block oil or coolant ingress, while the D length and 112 size codes indicate the stack height and lamination diameter used to reach the stated torque density.
Dynamic holding requirements are handled by an integral brake that produces 70.0 Nm of torque, keeping the axis stationary during power loss or safety stops. Position feedback is provided by digital servo feedback (HSF), and the internal sensor reports incremental counts interpreted as relative positions, so homing is necessary after each power cycle. The smooth plain shaft transmits torque without keyways, reducing backlash in clamp-style couplings. Connection to a drive inverter is matched to winding code 024, and power reaches the stator through an output connector that locks with a quarter-turn mechanism for a secure connection.
