Product Description:

The MHD115C-058-NP0-BA is a servo motor in the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It converts electrical energy into precisely controlled rotary motion for positioning and feed drives in automated equipment. It links directly to drive controllers through its series-specific electrical interface.

This model can deliver a continuous standstill torque of 70.0 Nm, allowing it to hold heavy loads without overheating during static phases. A centering diameter of 180 mm aligns the flange concentrically with machine frames, ensuring minimal radial runout. Position information is provided by Digital servo feedback (HSF), which supplies high-resolution incremental signals to the drive for tight speed and position loops. Heat is removed through natural convection; fins on the housing let ambient air carry heat away, eliminating the need for external blowers. Mechanical power leaves the motor through a keyed shaft, so torque is transmitted positively into couplings or pulleys while preventing slippage under peak load. The unit is supplied without a holding brake, so external clamping devices or drive torque must secure the axis during power-off conditions. A shaft seal is fitted to restrict the ingress of oil or dust along the output journal, and winding code 058 corresponds to the resistance and inductance values expected by compatible inverters.

The square mounting flange measures 192 mm, giving a standardized bolt pattern that matches other size-115 machines. Within the series classification, the frame size is 115, and the magnetic stack is the medium-length C build, which balances torque against overall mass. Position data is incremental, so motion control relies on relative displacement values referenced to a homing cycle. Power cables exit the housing on side B through an output connector, simplifying routing when the motor is installed in tight enclosures.
