Product Description:
The MHD115B-058-PP1-AN servo motor is produced by Bosch Rexroth Indramat as a member of the MHD Synchronous Motors series. Designed for automated production lines, it converts regulated electrical power into precise mechanical rotation that drives conveyors, pick-and-place heads, or forming tables. By pairing its internal feedback circuitry with a compatible drive controller, the unit supports coordinated multi-axis motion where accuracy, repeatability, and rapid duty cycles are required. Its operating concept suits machines that need smooth response during frequent starts, stops, and position changes.
The motor delivers a continuous standstill torque of 50.0 Nm, allowing static loads without overheating. It uses a 180 mm centering diameter, a motor size of 115, and a B length code for its basic frame geometry. Thermal limits are managed by liquid cooling, so F-class insulation stays within its temperature range during sustained operation. The housing is sealed to IP65, and a shaft seal helps keep contaminants out while limiting lubricant escape. Winding code 058 indicates the electrical resistance and inductance used by the matching drive, and the digital servo feedback encoder provides absolute position data over more than 4096 revolutions with a system accuracy of ±0.5 angular minutes. Power enters through an output connector oriented on side A of the housing, which supports orderly cable routing.
For dynamic holding and safety, the motor is supplied with a holding brake that delivers 70.0 Nm of torque so vertical or indexing axes remain fixed when the drive is disabled. Installation is supported by a square flange that measures 192 mm per side, giving a broad mounting face for machine attachment. The unit operates in ambient temperatures from 0 to 40 °C and may be stored between −20 and +80 °C without damage, provided the installation site does not exceed 1000 m above mean sea level. Motion is detected by optical measurement methods, allowing noncontact feedback operation during closed-loop control.
