Product Description:

The MHD115A-035 is a servo motor produced by Bosch Rexroth Indramat and supplied within the MHD Synchronous Motors series. Designed for closed-loop industrial drive axes, the unit transforms three-phase electrical input into precise mechanical rotation for packaging lines, metal-cutting centers, and automated transfer stations. Permanent-magnet excitation and integrated position feedback enable tight regulation of speed and torque so machine cycles remain synchronized with process commands. Its construction follows IEC mounting conventions, allowing straightforward integration with gearboxes or belt transmissions used in multi-axis assemblies. It can also support applications that require accurate starting, stopping, and speed changes throughout repeated operating cycles.

The mechanical interface of the motor features a 180 mm centering diameter that seats the housing against the machine frame and helps keep radial runout within tolerance. Surrounding that pilot, the square flange spans 192 mm and provides standardized bolt holes for secure mounting. During continuous operation at standstill, the electromagnetic package delivers 32.0 Nm of torque without exceeding winding temperature limits, which suits presses, clamps, or vertical axes that must hold a load for extended periods. The unit is a Servo Motor and accepts high-frequency current modulation from digital drives to reproduce commanded motion profiles. The frame is identified as Motor size 115, which aligns the stator diameter with compatible power modules.

The compact build uses Motor length A, the shortest stack offered for this diameter, and the reduced axial dimension lowers mass and inertia for faster response to acceleration commands. The motor uses Winding code 035, which sets the resistance and inductance values that influence current draw and voltage behavior with the selected inverter. Heat moves from the stator to the housing through aluminum ribs that guide air across the outer surface, supporting stable thermal performance during repetitive motion. A splined shaft accepts couplings or pulleys without secondary machining, and the shorter housing can make placement easier in compact machine sections.
