Product Description:

The MHD112B-035-PG2-AN servo motor is manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It is intended for industrial automation axes that demand repeatable rotary positioning and torque control. By integrating a digital feedback encoder into the housing, the motor links directly to drive controllers that handle velocity, position, and spline interpolation for machine tools, packaging stations, and handling gantries.

The motor’s electromagnetic section uses design code 035 and delivers a continuous torque at standstill of 28.0 Nm. Heat generated during that load is removed through liquid cooling, allowing the stator to maintain thermal balance while maintaining Class F insulation integrity. Mechanical mounting uses a 192 mm square flange that aligns with a 130 mm centering diameter, securing the 112-frame stator without shims. An IP65 enclosure surrounds the laminations, so airborne dust and directed water jets do not enter during washdown cycles. The digital servo feedback encoder uses an optical measurement method and provides absolute position data to the drive, while the power conductors exit on side A through an output connector. Motor length code B corresponds to the intermediate rotor stack within this frame size.

A spring-applied holding brake supplies 32.0 Nm of static torque to keep the plain shaft stationary when the drive is disabled, and a shaft seal is fitted so lubricant does not migrate past the journal. Absolute multi-turn detection over more than 4096 revolutions combines with a system accuracy of ± 0.5 angular minutes to support contouring applications that require minimal cumulative error. The motor can be installed up to 1000 m above mean sea level and run in ambient temperatures from 0 to 40 °C. During storage, it tolerates temperatures between -20 to +80 °C without degradation of magnetic or insulation properties.
