Product Description:

The MHD112B-035-NP1-RN is a servo motor built by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. Within an automated cell, it acts as the prime rotary actuator that receives drive commands from a digital controller through its integrated optical feedback system. The encoder uses digital servo feedback to relay rotor position, allowing precise speed and angle control in packaging lines, machine tools, and material-handling gantries. This arrangement lets the connected drive monitor motion continuously and correct deviations during rapid speed changes or positioning moves.

At the mechanical level, the motor can deliver a continuous standstill torque of 28.0 Nm, giving steady holding force for axes that remain loaded for long cycles. Heat from the windings is removed through liquid cooling channels around the stator housing, so thermal limits are maintained even during load peaks associated with winding code 035. The enclosure carries an IP65 rating, which helps protect the frame against dust and water jets. Mounting interfaces follow IEC dimensions, with a centering pilot of 130 mm for alignment and a square flange of 192 mm for attachment to gearboxes or machine plates. Power conductors exit to the right through a connector, and a keyed shaft with a shaft seal transfers torque without lubricant loss.

For static emergency stops, the factory-installed holding brake supplies 22.0 Nm of braking torque and is released automatically when power is applied. Position feedback resolution supports a system accuracy of ± 0.5 angular minutes, which suits coordinated multi-axis interpolation. Ambient operation is permitted from 0 to 40 °C, and storage is permitted from -20 to +80 °C without damage to the F-class insulation or the liquid jacket. The maximum installation height is 1000 m above mean sea level, and the motor uses relative position detection, so an external homing routine is required at startup.
