Product Description:

The MHD115C-058-PP0-AA is a servo motor from Bosch Rexroth Indramat’s MHD Synchronous Motors series. The unit converts current from a drive controller into rotary motion for positioning axes, conveyors, and other automated machinery that require closed-loop speed and torque regulation. Its keyed shaft provides secure mechanical engagement with couplings or pinions, and the frame is sized for 115-class installations used in general industrial equipment. This motor layout supports repeatable motion in applications that require controlled acceleration, steady running speed, and accurate stopping.

The motor delivers 70.0 Nm of continuous torque at standstill, which indicates how much stationary load it can hold without overheating. A centering pilot of 180 mm aligns the motor on the machine plate, while the 192 mm flange fits mounting patterns common to this frame size. Heat generated in the windings is removed by natural convection, so the installation should allow free airflow around the housing. Power leads exit on side A through a quarter-turn bayonet connector, which helps keep cable routing secure. The keyed shaft transfers torque without slip, and the C-length magnetic stack suits indexing tables and other axes that need a balance between inertia and acceleration.

The motor uses winding code 058, which identifies the electrical winding configuration for the matching drive controller. Position is reported by an absolute feedback system that tracks more than 4096 revolutions, and the integrated digital servo feedback encoder supplies real-time data for commutation and position monitoring. A shaft seal helps block dust and oil at the output end. The motor is supplied without a holding brake, so vertical or suspended loads must be secured by external locking or drive torque when power is removed. It has a C-length housing and a model-specific output connector orientation.
