Product Description:

The MHD112B-024-NG1-BN is a servo motor developed by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as a drive element that converts electrical energy into controlled rotary motion for positioning tasks in automated machinery and transfer lines. By integrating with drive controllers, the motor delivers closed-loop speed and torque regulation that supports repetitive, high-precision cycles in industrial automation cells.

The motor can produce a continuous standstill torque of 28.0 Nm, allowing it to hold static loads without overheating when energized. Heat generated at this load is removed by liquid cooling, so the motor sustains duty cycles that would thermally limit an air-cooled unit. Mounting is assisted by a 192 mm square flange and a 130 mm centering diameter that align the stator face with gearboxes or frames. Rotor position is tracked by digital servo feedback (HSF), enabling high-speed current control and immediate detection of position deviations. A plain shaft design supports direct coupling, and a shaft seal prevents lubricant from migrating into the stator cavity. The unit is delivered with a holding brake, so the axis can remain stationary when power is removed.

The brake supplies 22.0 Nm of static torque, enough to secure typical payloads attached to this frame size. Power and feedback cables exit the housing on side B, simplifying routing inside cabinets where several motors share a common harness path. Within the series, the frame code identifies a size-112 stator diameter, and the B length extends stack depth for higher magnetic flux without changing the mounting pattern. Relative position detection is inherent to the feedback type, while commands reference absolute machine coordinates held in the controller. The motor uses an output connector for power conductors, and winding code 024 ties the coil resistance and inductance to compatible drive inverters.
