Product Description:

The MHD115B-058-PP1-BA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. This motor serves as a rotary actuator in automated machinery, where it delivers precise speed and position control through its integrated digital feedback encoder. Natural convection cooling allows the unit to dissipate heat without external airflow hardware, and the keyed shaft provides positive mechanical engagement with couplings or pulleys while a factory-installed shaft seal helps limit lubricant escape.

During continuous duty, the motor can hold a load with 50.0 Nm of torque at standstill, and the holding brake supplies an additional 70.0 Nm to secure axes when power is removed. The front flange measures 192 mm and mates with standard ISO mounting faces, while the pilot diameter supports accurate alignment during installation. An enclosure rating of IP65 permits installation in dusty or splash-prone areas, and the motor is suitable for ambient temperatures from 0 to 40 °C. Thermal endurance is reinforced by Class F insulation, while the motor length code B and size 115 indicate the stack height and stator frame selected for mid-range torque density. Power enters through an output connector on side B of the housing, which can simplify cable routing in tight machine frames.

The integrated optical measurement system supplies absolute position data over more than 4096 revolutions with a system accuracy of ±0.5 angular minutes, supporting fine positional corrections in closed-loop drives. Digital servo feedback is transmitted through the same connector set, which keeps the feedback arrangement compact. Altitudes up to 1000 m above mean sea level are permissible without derating, and storage is allowable from -20 to +80 °C. The winding design follows code 058, and the insulation class is F, giving the stator additional tolerance for transient temperature rise during rapid indexing cycles.
