Product Description:

The MHD115B-024-NG0-RN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Used with a compatible drive controller, it converts regulated electrical input into controlled shaft rotation for positioning axes and speed-regulated motion. This makes it suitable for automated presses, gantry systems, and material-handling equipment that need repeatable response under changing load conditions. The synchronous design supports closed-loop operation, so commanded speed and torque can be adjusted quickly while the motor remains compact for its output class.

This motor supplies a continuous standstill torque of 50.0 Nm, allowing the axis to hold substantial load at zero speed without excessive heat rise. A centering pilot of 180 mm aligns the motor on the machine interface, and the square flange of 192 mm provides a rigid mounting surface. Heat is removed by liquid cooling, with coolant passing through internal channels near the stator to support higher thermal loading than a comparable air-cooled design. Unlike simple fan-cooled units, this arrangement places coolant close to the stator laminations, which helps limit temperature rise during sustained load. The motor uses high-speed digital servo feedback to report rotor position relative to a reference mark, so the drive tracks motion precisely during acceleration, speed regulation, and positioning moves.

The motor is supplied without a holding brake, so load retention during power loss must be provided by the machine or the drive system. Electrical connection is made through a power connector oriented to the right, which can simplify cable routing when several axes are installed in a line or when cabinet entries are placed on one side of the machine. The output uses a plain shaft for couplings or pulleys, and a fitted shaft seal helps protect the bearing area from coolant or oil ingress. This layout supports clean mechanical integration at the drive end without adding unnecessary complexity.
