Product Description:

The MHD115B-024-NG1-AA servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. Designed for precision positioning and speed regulation, it provides the electromechanical interface between a drive controller and the moving elements of automated packaging, material-handling, and machining equipment. The unit converts three-phase electrical power into controlled rotary motion so that programmed profiles are followed with minimal deviation, improving cycle repeatability and overall process throughput. Its stator-rotor assembly and integrated feedback provide the stiffness needed for high dynamic loads. This operating principle supports repeatable starts, stops, and short settling times in axes that reverse direction frequently.

At standstill, the motor can maintain 50.0 Nm of continuous torque, which is the maximum load it can hold indefinitely without overheating. During power-off events, a holding brake provides 70.0 Nm, keeping vertical axes fixed until power returns. Position data comes from digital servo feedback (HSF), which sends high-speed signals to the controller for tight velocity loops. That feedback lets the controller correct position and speed deviations quickly during acceleration and deceleration. Thermal energy leaves the laminated core through natural convection, eliminating the need for forced ventilation when the motor is mounted in free air. Mechanical centering is simplified by a 180 mm pilot diameter that mates with standard machine frames.

The mounting flange measures 192 mm across, and the motor length is code B, giving a moderate axial footprint for the 115 frame. A plain shaft with a factory seal helps prevent lubricant escape and blocks airborne contaminants. This shaft arrangement is suitable for installations where dust or light contamination may be present around the drive train. Power conductors exit on side A through a connector, which streamlines cable routing along the drive end and keeps the cable outlet on a consistent side of the housing. Winding code 024 indicates the electrical characteristics used with compatible inverters, while the relative detection method lets the control system establish an absolute reference after homing.
