MHD112A-058-PG0-BN

The MHD112A-058-PG0-BN servo motor is manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for electrically commutated drive systems where precise speed and position loops are required. By pairing with compatible Rexroth inverters, this motor converts electrical input to controlled mechanical rotation for automated machine axes, material handling stations, and synchronized production lines. Its winding code 058 defines the electrical constants that match standard Rexroth power stages.

This model produces a continuous standstill torque of 15.0 Nm, giving the drive sufficient holding capacity for static duties without additional gearing. A centering diameter of 130 mm aligns the stator housing with adjoining machine frames, while the square flange measures 192 mm on each side to fit standardized mounting patterns. Heat generated in the windings is extracted through Liquid cooling, so the motor can maintain its rated output when installed in sealed cabinets or high-ambient zones. Rotor position is monitored through Digital servo feedback housed in the end-bell, enabling high-resolution control loops and automatic commutation.

Additional mechanical and electrical details finalize its integration profile. The rotating element uses a Plain shaft, allowing direct coupling with clamping hubs or keyed bushings, and there is a Shaft seal that limits lubricant migration into the bearing cavity. Power leads terminate in an output connector oriented to side B, simplifying cable routing in multi-axis cabinets. An absolute measuring system capable of more than 4096 turns, noted as Absolute (>4096 revolutions), enables homing-free startup. Motor size 112 and length A construction give designers predictable resistance, inductance, and inertia values for medium-load applications.
