Internal Product Review
The MHD115B-035-PP1-AA is a Bosch Rexroth Indramat servo motor with IP65 protection. Natural convection cooling and digital servo feedback with integrated encoder give the design efficient thermal behavior and clean closed-loop response. Absolute position detection beyond 4096 revolutions makes the model especially attractive for repeatable, high-confidence positioning.

Product Description:
The MHD115B-035-PP1-AA is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as a closed-loop drive element, converting commanded current from a compatible inverter into regulated rotary motion for packaging machines, handling systems, and metal-cutting spindles. The motor integrates digital servo feedback so that controllers receive absolute position signals across multiple turns, allowing quick startup without manual referencing. This feedback arrangement helps the axis return to controlled motion after power cycling without a separate homing routine.
Mechanically, size code 115 and length code B give the unit a compact profile while delivering a continuous standstill torque of 50.0 Nm to hold or accelerate medium-mass loads. The square mounting flange is 192 mm across, and a built-in holding brake supplies 70.0 Nm of static torque to secure vertical axes at rest. The brake is intended to hold the load when the axis is stopped rather than serve as the primary means of deceleration during normal motion. Protection rating IP65 helps keep dust and low-pressure water jets out of the housing, and heat is removed through natural convection, so no external fan is required. The encoder uses optical digital servo feedback and provides absolute position data for more than 4096 revolutions through a single-cable output connector on side A. Winding code 035 sets the electromechanical characteristics used by matching drive amplifiers.
Installation accuracy is aided by a centering diameter of 180 mm, while the drive interface uses a keyed shaft that resists slip during repetitive cycling. The feedback system supports positional repeatability within ± 0.5 angular minutes, which is suitable for synchronized multi-axis applications. Operation is permitted up to 1000 m above sea level, with ambient temperatures from 0 °C to 40 °C and storage from -20 °C to 80 °C. Class F insulation supports elevated internal winding temperatures, and a shaft seal helps keep lubricant in place while limiting the entry of contaminants.
