Product Description:

The MHD115B-024-NG0-LN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Within an automation cell, it converts drive controller commands into mechanical rotation for positioning axes, conveyors, and forming tools that demand high torque density and precise feedback. Its synchronous design allows accurate control of speed and torque during repeated start-stop motion. This supports consistent axis response in equipment that runs under changing loads.

A centering shoulder of 180 mm aligns the frame to machine tooling so runout remains minimal. The motor can hold loads with a continuous standstill torque of 50.0 Nm, allowing static press or vertical-axis duties without overheating. Rotor position is reported through Digital servo feedback (HSF), which supports tighter velocity loops and smaller following errors. Mounting is completed on a square flange that measures 192 mm, giving bolt spacing suited to the housing. Heat is removed by an internal jacket that supports liquid cooling, which helps keep winding temperature stable during extended peak cycles. Three-phase power reaches the stator through a keyed power connector, which simplifies connection and line-side isolation without terminal rewiring.

The output interface is a plain shaft with a shaft seal that helps block coolant mist and dust from the front bearings. Because the unit is supplied without a holding brake, the load must be locked mechanically or held by drive torque during idle states. Size code 115 with length code B gives the motor a compact envelope for its torque class. Position evaluation is relative, so the controller performs a reference move after power-up to establish machine zero. Winding code 024 corresponds to the electrical resistance and inductance values expected by compatible Rexroth inverters, and the power lead exits to the left to suit cable trays on gantry columns and press lines.
