Product Description:

The MHD115C-024-PP1-AN is a brushless servo motor from Bosch Rexroth Indramat in the MHD Synchronous Motors series. Its size 115 frame and C-length housing fit mid-range axes. A liquid-cooled stator works with digital servo feedback, allowing the drive to read absolute position over more than 4096 revolutions. This combination supports accurate motion on axes that cycle frequently under varying loads. In presses, gantry axes, and palletizers, the unit supplies programmable torque and speed that replace mechanical cams and hydraulic cylinders.

At standstill, the motor can deliver 70.0 Nm continuously, allowing heavy loads to remain clamped without overheating because internal coolant passages remove heat from the stator. Its face and terminal box are sealed to IP65, preventing dust ingress and water jets from affecting the windings during washdown. Those windings use liquid cooling, in which circulating fluid carries heat directly away from the stator for higher duty cycles than air-cooled machines. Closed-loop accuracy of ±0.5 angular minutes comes from the optically sampled absolute encoder, while the 180 mm centering diameter aligns the flange concentrically on precision gearboxes and machine frames. Stator winding code 024 matches drives that supply the required current profile, and power is routed through an output connector on side A of the housing to simplify cable runs.

The mechanical interface uses a 192 mm square flange, so the motor can replace earlier MHD units without adapter plates. Reliable output is maintained between 0 to 40 °C, and Class F insulation tolerates internal temperatures up to 155 °C during intermittent overloads. Installation is permitted up to 1000 m above MSL without derating, which supports factory mezzanines and high-elevation plants. When stored, the motor can withstand temperatures from -20 to +80 °C without damage. A keyed shaft and a shaft seal help prevent slip and fluid migration, and the holding brake keeps vertical axes secure when power is removed.
