Product Description:

The MHD112A-058-PP2-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. As an electromechanical drive element, this motor converts electrical energy from a regulated inverter into precise rotational motion for axes that demand closed-loop control in industrial automation equipment such as packaging stations, gantry axes, and transfer modules. It is suited for applications that require accurate speed regulation, repeatable positioning, and stable torque response during changing load conditions. That combination makes it appropriate for synchronized machine motion where the drive must react quickly to command changes.

The motor delivers a continuous standstill torque of 15.0 Nm, enabling stable holding or low-speed motion without thermal overload. Its enclosure carries an IP65 rating, so sealed joints and cable exits protect the stator windings against dust ingress and low-pressure water jets encountered on the factory floor. Heat generated in the stator laminations is extracted through liquid cooling, which permits higher torque density than convection-cooled housings. An internal spring-applied brake supplies 32.0 Nm of static torque to secure vertical or indexing axes whenever power is removed. Closed-loop feedback uses digital servo electronics that resolve rotor angle with a system accuracy of ±0.5 angular minutes, supporting coordinated multi-axis motion.

The motor has a centering diameter of 130 mm and a square flange side of 192 mm; this geometry aligns the shaft with gearboxes or couplings and provides a reference for dowel pins during installation. During operation, the unit may run in ambient temperatures from 0 to 40 °C, and it can be stored between -20 and +80 °C without damage to the magnets or insulation. Class F insulation permits winding temperatures up to 155 °C while the liquid jacket helps keep thermal stress under control. Additional features include a keyed shaft with a shaft seal, optical absolute position detection beyond 4096 revolutions, winding code 058 for electrical matching, a power connector on side B, and suitability for machine elevations up to 1000 m above mean sea level.
