Product Description:

The MHD112B-048-PG0-AN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It supplies controlled torque and speed to automated axes by linking directly to a compatible Indramat drive for coordinated motion. The motor houses an integrated encoder to relay position data, so it can maintain tight velocity loops in conveyor sections, pick-and-place heads, and similar high-cycle installations. This layout supports repeatable acceleration and deceleration on machinery that starts and stops frequently during normal operation.

Its continuous torque at standstill is 28.0 Nm, enabling the shaft to hold loads without overheating when stationary. The motor uses a 192 mm square flange and a 130 mm centering diameter, allowing rigid mounting on gearboxes or direct-drive frames while keeping concentricity errors low. Thermal losses are removed through liquid cooling; coolant channels in the housing extract heat so the motor can run at rated current even inside sealed enclosures. Feedback is provided by digital servo feedback, which combines incremental and absolute information for high-resolution control. The power conductors exit toward side A through an output connector, which helps keep cable routing orderly in cabinets with fixed raceway layouts.

The drive side uses a plain shaft that accepts couplings or pulleys without keyways, which can help reduce vibration at high speeds. The encoder provides absolute feedback for more than 4096 revolutions, so the axis can recover its coordinates immediately after power is restored. The unit has motor size 112 and winding code 048, which are used to match the motor to the correct drive settings and application range. A shaft seal is fitted to protect the bearings from splash and oil mist, and the motor is supplied without a holding brake, so external clamps or drive torque must secure vertical loads during shutdown.
