Product Description:

The MHD112D-027-NG0-AN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended to drive coordinated axes in factory automation, providing controlled rotary motion wherever regulated torque and speed are required in transfer, positioning, and handling systems. Classified as a servo motor, it accepts position commands and returns feedback to the control loop, allowing closed-loop operation in diverse motion tasks where stable response and repeatable positioning are important.

A centering diameter of 130 mm aligns the front flange concentrically with the driven machine. At standstill, the rotor can deliver 48.0 Nm of continuous torque, which helps with gearing and load matching in axis design. Position and velocity data are returned through digital servo feedback (HSF), giving high-speed sampling for tight control. The mounting face spans 192 mm, and the frame uses liquid cooling passages so circulating coolant can remove heat without relying on ambient airflow. This motor is supplied without a holding brake, so static load retention must be handled by external mechanics or servo clamping.

The stator stack corresponds to motor length D, providing a longer active core than shorter codes in the same size 112 family. Power leads exit on side A, which can simplify cabinet routing when the motor is installed close to fixed panels, and power is supplied through an output connector that mates directly with Rexroth drive cabling. A plain shaft transmits torque without keyways or serrations, and a shaft seal limits lubricant escape and dust ingress. Winding code 027 indicates the electrical resistance and inductance set used with compatible Indramat drives for mid-range speed applications. The feedback reports position in a relative manner, so the axis requires homing after each power cycle.
