Product Description:

Bosch Rexroth Indramat manufactures the MHD112A-024-PG1-AN, a servo motor in the MHD Synchronous Motors series. It is intended for closed-loop industrial axes where position, speed, and torque are commanded precisely by a drive controller. The unit converts electrical power into mechanical rotation for packaging lines, machine tools, and material-handling modules, while its integrated feedback returns real-time rotor position data to the control system. Its high torque density and thermally efficient housing support compact installation in cabinets where ambient temperatures may already be elevated.

In continuous duty, the motor can provide 15.0 Nm of standstill torque, and thermal energy is removed by liquid cooling, so full current can be applied without overheating. The enclosure is rated IP65, which helps protect the internal windings from dust ingress and water jets during washdown. Mechanical mounting uses a square flange that measures 192 mm on each side and a centering recess of 130 mm. A plain shaft with a factory-installed shaft seal limits lubrication loss. Electrical power enters through an output connector on side A, while digital servo feedback from an integrated optical encoder is sent to the controller. The built-in holding brake engages automatically during shutdown to secure vertical or suspended loads.

The brake develops 22.0 Nm of static torque, and the encoder provides position data with an accuracy of ±0.5 angular minutes. Multi-turn tracking with absolute tracking over more than 4096 revolutions eliminates homing after power-up. The motor uses winding code 024, motor length A, and frame size 112 for its electromagnetic package. Copper conductors use Class F insulation. The operating ambient temperature range is 0 to 40 °C, and storage is permitted from −20 to 80 °C. The design also supports installation up to 1000 m above mean sea level without derating, and a positive shaft seal helps block coolant or oil from entering the stator cavity.
