Product Description:

The MHD112B-058-PG0-BN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for closed-loop motion tasks, the unit converts electrical energy into precisely regulated mechanical rotation that drives tooling heads, gantry axes, and integrated handling modules in industrial automation cells. Its construction supports high duty cycles and electronic coordination with digital drives, making it a core actuator wherever repeatable speed and torque curves are required. The motor is intended for applications that need accurate starts, stops, and speed changes under varying load conditions. This makes it suitable for packaging, material-handling, and machine-tool subsystems that depend on synchronized axis motion.

The motor has a centering diameter of 130 mm, allowing the flange to seat accurately on gearboxes or machine frames. Under continuous stall conditions, the stator can deliver 28.0 Nm without exceeding thermal limits, supplying steady force for holding or low-speed feed motions. The square flange measures 192 mm, providing a standardized mounting face for compatible mechanical interfaces. Heat generated in the windings is removed through liquid cooling, so output can be sustained even in tightly sealed cabinets. Electrical power reaches the stator through a connector on side B, which can simplify cable routing when the rear of the motor faces the cabinet wall. This mounting and cooling arrangement helps maintain alignment and stable thermal behavior during long production runs.

Feedback and internal sensing use digital servo feedback with an integrated encoder, transmitting absolute position data across >4096 revolutions for fine closed-loop control without homing cycles. The rotor uses a plain shaft, so couplings or pulleys can slide on without keyways when zero-backlash connections are preferred. Electromagnetic behavior is set by winding code 058, aligning resistance and inductance with compatible drive amplifiers for fast current response. Because the encoder is integrated, the drive can monitor rotor position continuously during acceleration, deceleration, and standstill. An internal shaft seal helps limit the entry of coolant splash and dust at the shaft area. The shaft style is also well suited to clamp couplings and other hub connections used on precision axes.
