Product Description:
The MHD112D-027-PG0-AN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It drives coordinated motion axes in automated machinery that require rapid acceleration and precise positioning. By coupling directly to the load, the motor supplies controlled torque and speed under electronic drive supervision, forming a compact electromechanical actuator for CNC and assembly equipment. This layout supports responsive servo control in transfer systems, machine tools, and indexing applications.
A centering diameter of 130 mm and a 192 mm square mounting flange set the bolt pattern for rigid installation. The unit belongs to motor size 112 and length code D, giving a stator stack suited for medium continuous duty. At standstill, it can supply 48.0 Nm of continuous torque, so thermal saturation is avoided during static holding or slow indexing. Heat is removed through an internal jacket that provides liquid cooling, enabling higher current density than air-cooled designs. An integrated encoder furnishes digital servo feedback for high-resolution velocity loops and tight synchronous operation. Power enters through an output connector facing side A, which helps simplify cable routing inside the cabinet.
The rotor features a plain shaft so couplings or pulleys can be mounted without keyways. Motion retention during power loss is handled externally because the motor is supplied without a holding brake. A shaft seal limits coolant splash and dust ingress along the journal. Absolute position tracking over more than 4096 revolutions is provided by the encoder’s Absolute (>4096 revolutions) capability, eliminating homing after startup. The winding code 027 identifies the electrical characteristics used with compatible Indramat drives.
