Product Description:

The MHD112A-058-PG0-AN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Motor size 112 with the A length code gives the unit a compact format for closed-loop axes in assembly cells, machining centers, and automated handling lines. Integrated digital servo feedback supplies absolute position data to the drive controller, allowing precise velocity and position regulation during coordinated motion sequences. This arrangement supports repeatable starts, stops, and synchronized movement in machinery that must maintain accurate axis control throughout demanding production cycles.

The motor produces a continuous standstill torque of 15.0 Nm, giving machinery stable holding force at zero speed. The enclosure is rated IP65, so internal components are protected against dust and water jets common on factory floors. Heat is removed by liquid cooling, which helps keep the housing and winding package within safe temperature limits during sustained operation. An optically scanned encoder supplies absolute multi-turn feedback and supports a system accuracy of ± 0.5 angular minutes, enabling fine positioning without external scales. Because the motor has no holding brake, vertical axes must rely on external clamping or drive torque for secure parking, while power and feedback leads exit on side A through an output connector and a shaft seal protects the lubrication zone at the shaft interface.

Service limits permit operation from 0 to 40 °C, while storage from -20 to +80 °C helps protect the motor during transport and idle periods. Windings built to Class F insulation tolerate the elevated internal temperatures associated with this motor design. A centering diameter of 130 mm aligns the housing precisely on gearboxes, and the rotor uses a plain shaft that supports direct coupling to hubs or shrink-fit elements. The motor uses winding code 058 for its electrical configuration, and the absolute encoder tracks more than 4096 revolutions so homing is not required after power is restored. Installation is permitted up to 1000 m above sea level, which allows the motor to be used in a wide range of industrial environments without changing its basic application role.
