Product Description:
The MHD112B-048-PG1-AN is a servo motor from Bosch Rexroth Indramat within the MHD Synchronous Motors series. It converts electrical power from a drive into controlled mechanical rotation for positioning and velocity tasks in automated machinery such as gantries, tooling spindles, and material-handling axes. The frame is engineered for high power density, permitting continuous operation in demanding duty cycles without external gear reduction. It integrates with compatible digital drive controllers through an embedded feedback interface and a pre-assembled power connector. This makes the motor suitable for applications that require smooth acceleration, stable speed control, and repeatable axis motion.
The motor delivers a continuous standstill torque of 28.0 Nm, allowing machines to hold a load without overheating when stationary. Installation is aligned by a centering diameter of 130 mm, and the mounting interface matches a flange of 192 mm, so it fits machine frames sized for the 112 family. Heat generated by the windings is removed through liquid cooling, permitting higher current density than air-cooled housings. A built-in brake rated at 22.0 Nm secures vertical or indexing axes when power is removed. The motor has a plain shaft with a shaft seal, and length code B provides a balanced combination of inertia and torque capability. Digital servo feedback with an integrated encoder supplies rotor position data to the drive controller.
Absolute multi-turn sensing with Absolute (>4096 revolutions) supports homing-free startup and accurate indexing after each cycle. Power is routed through the designated terminal on side A, and an output connector permits quick disconnection without rewiring the drive cabinet. Winding code 048 identifies the electrical winding used for this stator size. The connection layout keeps the power interface organized and supports compact machine arrangements.
