Product Description:

The MHD115B-024-PG0-BN belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. As a servo motor, it converts drive current into controlled rotary motion for positioning tasks in handling modules, packaging lines, and machine tools. Its integrated encoder enables closed-loop feedback so the drive controller can correct position and speed errors in real time. That closed-loop operation helps the motor maintain accurate movement during repeated starts, stops, and speed changes.

This model supplies a continuous standstill torque of 50.0 Nm, giving machines ample holding force during dwell periods. A centering diameter of 180 mm aligns the motor accurately to the mounting face, while the flange measures 192 mm across for compatibility with larger gearheads and couplings. Heat is removed through liquid cooling, allowing rated output without external airflow during continuous duty. Position data is generated by a digital servo feedback system, and the motor stores shaft position as absolute feedback over more than 4096 revolutions, so a reference move is not required after power loss. The motor has frame size 115 with length code B. It is supplied without a holding brake, so static load retention must be provided externally, and a shaft seal helps limit lubricant escape in oil-splash areas.

The output interface uses a plain shaft, which supports direct coupling with suitable clamping or keyed elements. Electrical behavior follows winding code 024, which matches the parameter set used by the connected drive. Power conductors exit on side B through an output connector, and the feedback cable runs in the same direction to keep routing compact around the motor. Routing both cable groups the same way can also help reduce tight bends near the housing when installation space is limited.
