Product Description:

The MHD112D-027-PG0-BN is a servo motor from the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It serves as a torque source for industrial automation axes, converting drive current into controlled rotary motion for positioning tables, gantry systems, and material-handling equipment. Integrated digital servo feedback and a built-in encoder let the controller monitor shaft position continuously during closed-loop operation. Because the feedback system is integrated into the motor housing, the drive can regulate speed and position with fewer separate components in the control loop.

This model delivers a continuous standstill torque of 48.0 Nm, so it can hold a stationary load while energized. A centering diameter of 130 mm helps align the motor to the machine interface, and the square flange dimension of 192 mm provides the mounting pattern for installation. Heat is removed by liquid cooling, which helps stabilize internal temperature during demanding duty cycles and sustained low-speed operation. The electromagnetic layout uses winding code 027, and the mechanical package uses length class D for this frame. This cooling method is useful where repeated acceleration and high current demand would otherwise raise winding temperature quickly.

The motor uses size code 112, which refers to the active lamination diameter for this model. Power leads exit the housing on side B, which can simplify cable routing when several axes are mounted close together. Absolute position detection is available for more than 4096 revolutions, allowing position retention after power cycling without a homing move. The plain shaft is suited to backlash-free couplings or pulley hubs that clamp directly to the shaft surface, and the shaft seal helps limit coolant entry. Because no holding brake is installed, static parking must be handled by the drive or an external clamp when the motor is not powered.
