Product Description:
The MHD112A-035-NP1-BN is a servo motor produced by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. As an electromechanical actuator in industrial automation, it converts the controlled electrical output of a drive into rotary motion suitable for positioning tasks on gantries, material-handling axes, and packaging equipment. The motor links to closed-loop control systems through its digital servo feedback encoder, allowing the controller to command precise velocity and position while monitoring the relative shaft angle in real time. That control loop helps the drive correct deviations during acceleration, deceleration, and dwell periods.
During steady stall conditions, the motor supplies a continual 15.0 Nm of torque, giving machinery enough holding force while axes dwell without overheating. Heat generated by copper losses is removed through liquid cooling, which circulates coolant along the housing so rated output can be maintained in compact cabinets and other enclosed machine spaces. A flange diameter of 192 mm forms the mounting face and supports accurate attachment to compatible machine brackets. The power cable exits toward side B, which helps keep conductors away from moving components and can simplify routing in machines with limited rear clearance. The keyed shaft provides positive mechanical engagement with couplings, the output connector supports direct electrical connection, and the A-length stator helps keep inertia moderate.
Mechanical alignment is aided by a centering recess of 130 mm, allowing the housing to seat accurately in the machine register before the flange bolts are tightened. The centering feature also helps maintain concentric alignment between the motor and the driven load. For vertical loads, the integrated brake applies 22.0 Nm of static torque to hold the axis when the drive is de-energized. A dedicated shaft seal helps block coolant or lubricant ingress at the output end. The motor uses winding code 035, and size 112 gives a balance of electromagnetic capacity and manageable mass.
