Product Description:

Bosch Rexroth Indramat manufactures the MHD115C-024-PG1-AA synchronous motor, a member of the MHD Synchronous Motors series. As a servo drive element, the unit converts command currents from a digital controller into rotational motion for positioning and cyclic transport tasks in automated machinery. With its integrated feedback device, it fits closed-loop axes used in packaging lines, material-handling gantries, and metal-forming stations. This configuration supports repeatable motion control in systems that need accurate speed regulation and stable positioning under changing loads. It is commonly used where the motor must respond smoothly to frequent starts, stops, and dwell periods.

At standstill, the rotor can deliver 70.0 Nm of continuous torque, allowing the axis to carry high static loads without overheating. Heat generated by the windings is dissipated through natural convection, so no external blower or liquid circuit is required and the housing transfers heat directly to the surrounding air. Position and speed are reported through digital servo feedback, which is integrated into the rear housing and supplies incremental and absolute data to the drive controller. The motor mounts by means of a 192 mm square flange, and power is transmitted through a plain shaft for direct coupling or belt-pulley use without a keyway. Passive cooling also avoids the extra space and wiring associated with auxiliary fan hardware.

For installation, the stator pilot diameter of 180 mm supports concentric seating within gearboxes and bearing plates, and the built-in brake can clamp the shaft during power-off conditions. Electrical leads exit the stator housing on side A, and the removable output connector allows cable disconnection without changing the motor’s mechanical fit. Multi-turn feedback provides absolute position tracking over more than 4096 revolutions, so homing cycles are not required after an emergency stop or an unexpected shutdown. The cable outlet arrangement helps preserve clearance around couplings and nearby machine elements. The motor uses winding 024, and the C length with frame size 115 places it in the larger section of the MHD platform for applications that need higher torque density.
