Product Description:

The MHD112D-024-PP0-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Intended for closed-loop axis control in transfer lines, machining centers, and automated packaging cells, it transforms commanded current from an Indramat drive into precise rotational motion. Integrated digital feedback reports rotor position to the controller, allowing the drive to synchronize speed, torque, and position with the application cycle. This feedback path helps the control loop react to load changes during acceleration, deceleration, and steady-state running. It can also support coordinated movement on machines that use multiple servo-driven axes.

The motor is aligned to the machine frame by a 130 mm centering diameter, and its mounting pattern follows a 192 mm flange size that fits the 112-frame envelope. The laminated stator provides 48.0 Nm continuous torque when energized, so the axis can deliver steady output during sustained operation. Heat is removed through liquid cooling, which supports full-duty use where cabinet airflow is limited or surrounding temperatures are difficult to manage. Rotor position is measured by digital servo feedback, and winding code 024 identifies the electrical winding used by the matching controller. Size code 112 and length code D indicate the frame and stack length, while the power leads exit through an output connector on side A to keep the coupling end clear.

For torque transmission, the motor uses a keyed shaft, and a shaft seal helps prevent coolant or lubricant from entering the stator chamber. The unit is supplied without a holding brake, so static load retention must be provided by the drive or an external clamp when the axis is stopped. It uses absolute feedback of more than 4096 revolutions, which preserves the position reference after power loss and reduces the need for repeat homing. This combination suits positioning tasks that need accurate restart behavior after power interruptions.
