Product Description:

The MHD112D-027-PP0-BN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. This model serves as a rotary actuator in industrial automation systems, converting drive current into tightly regulated mechanical motion for positioning tables, gantries, and tooling spindles. It can be paired with a compatible drive to support accurate speed control and repeatable positioning on production equipment. Its design suits machine axes that need stable torque response during frequent starts, stops, and direction changes. It is built in motor length D with liquid channels molded into the housing and integrates digital servo feedback for closed-loop operation. The motor is supplied without a holding brake, so any static load retention must be handled by external mechanics or the drive itself.

The motor can supply a continuous standstill torque of 48.0 Nm, allowing the axis to hold demanding loads while remaining within thermal limits. A flange measuring 192 mm sets the mounting bolt pattern, and the housing uses liquid cooling to remove copper losses during prolonged duty cycles. This cooling method carries heat away more effectively than passive cooling, which helps the motor maintain output in enclosed or high-duty installations. Power is transmitted through a keyed shaft, giving positive mechanical engagement with couplings or pulleys. Accurate alignment with the machine frame is established by a centering pilot of 130 mm, which helps the motor seat correctly during installation.

Rotor position is reported to the drive through absolute feedback for more than 4096 revolutions, so the controller knows the true shaft angle immediately after power-up. Multi-turn absolute feedback is useful on axes that must return to operation from a known position after power cycling. The power terminations use an output connector on side B, which helps route cables along the machine frame and can reduce bending at the connector. The winding uses code 027, and the motor has frame size 112 within the series. A shaft seal is fitted to help protect the internal bearings from coolant splashes and fine dust.
