Product Description:

The MHD115B-058-PG0-AN is a servo motor produced by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. As a compact electromechanical actuator, it couples directly to gearboxes, ball screws, or load shafts to provide precise speed and position control in machining centers, printing lines, and material-handling gantries. Integrated optical position sensing and absolute digital feedback allow the connected drive controller to close both torque and position loops, making the motor suitable for tightly regulated industrial automation tasks.

Its continuous torque at standstill is 50.0 Nm, so the axis can hold static loads without external brakes while keeping current within continuous ratings. The housing carries a protection rating of IP65, which seals the windings against dust ingress and low-pressure water jets during washdown. Internal channels support liquid cooling, removing generated heat and maintaining thermal margins during high cyclic duty. Mechanical alignment is simplified by a centering pilot of 180 mm, and the square flange measures 192 mm on each side, matching common IEC mounting patterns. The plain shaft, output connector on side A, and winding code 058 complete the mechanical interface.

Position precision is indicated by a system accuracy of ± 0.5 angular minutes, a figure backed by optical measurement inside the encoder. Because the motor is supplied without a holding brake, any static holding torque must be provided electrically or by an external mechanical lock. Continuous operation is permitted for ambient temperatures from 0 to 40 °C, while storage tolerates -20 to 80 °C. The windings use Class F insulation, and reliable performance is maintained up to 1000 m above mean sea level when the liquid-cooled housing is integrated into the machine's coolant circuit.
