Product Description:
The MHD112D-027-PP0-AN servo motor is produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed to convert electrical energy into controlled rotary motion, the unit provides closed-loop positioning and velocity control in automated conveyors, presses, and handling modules. By combining a compact 112 frame size with a liquid-ready housing, the motor supports high power density installations where precise motion and reduced maintenance downtime are required. This layout also suits machines that cycle frequently and need stable motion during repeated starts, stops, and direction changes.
At standstill, the motor delivers a continuous torque of 48.0 Nm, allowing stable holding force during indexing cycles without overheating. The centering collar measures 130 mm, while the square mounting flange spans 192 mm; these dimensions help align the shaft with gearboxes or direct-drive loads and fit common machine mounting grids. Heat is removed through a liquid jacket, and liquid cooling helps sustain rated output in confined cabinets. The housing length is coded D, and the 112 frame size corresponds to the stator diameter, which provides added copper volume for dynamic starts. The motor is supplied without a holding brake, so external clamping is required when power-off position retention is needed. A shaft seal is present to limit lubricant migration into the stator cavity. Power is routed through an output connector positioned on side A, which helps simplify cable routing in multi-axis assemblies.
For feedback, the motor uses digital servo feedback to communicate rotor position to the drive in real time. The encoder provides absolute position detection over 4096 revolutions, which removes the need for homing after power restoration and supports coordinated multi-axis motion. A hardened keyed shaft transmits torque without slip and helps with coupling alignment. Winding code 027 matches the motor to compatible drive parameters, and the power lead exits on the same side as the signal cable to support orderly cable routing and consistent electrical separation inside the machine.
