Product Description:

The MHD115C-059-NG0-AN belongs to the MHD Synchronous Motors series from Bosch Rexroth Indramat. It is a permanent-magnet servo motor intended for closed-loop industrial automation where precise torque and speed regulation are required. Integrated with compatible drive controllers, the unit converts electrical commands into controlled rotary motion for positioning tasks on packaging lines, gantry axes, and material-handling modules. This makes it suitable for systems that require repeatable motion and smooth servo response under changing loads.

This motor provides 70.0 Nm of continuous standstill torque, helping it resist static load forces when the axis is not moving. Thermal stability is supported by liquid cooling; coolant channels in the housing remove heat directly from the stator so full torque is available over longer duty cycles. Position data is returned through digital servo feedback (HSF), enabling the drive to execute high-resolution motion profiles without incremental loss. Machine mounting uses a square industrial flange that measures 192 mm across, supplying a standardized bolt pattern for rigid attachment to gearboxes or machine frames. For electrical integration, the power leads exit toward side A, which helps keep motor and feedback cabling on the same face of the machine.

Centering into the mating surface is guided by a 180 mm pilot diameter, which helps maintain concentric alignment between the motor and the driven load. The motor includes a shaft seal, so lubricant and contaminants are less likely to reach the internal bearing and stator area during operation. The rotor uses a plain shaft, allowing direct coupling where backlash must be kept low and no keyway is required. Electrically, the coils use winding code 059, and relative position detection allows the axis to establish its reference during homing before normal closed-loop operation begins.
