Product Description:

The MHD115B-024-NG0-RA belongs to the MHD Synchronous Motors series from Bosch Rexroth Indramat. It is a servo motor intended for drive axes that need precise speed regulation and strong torque output during production cycles. Within an automated line, the unit converts controlled electrical input from a drive controller into tightly regulated mechanical rotation that can be coordinated with sensors and PLC commands. This operating role makes it suitable for positioning, feed, and handling tasks where repeatable motion is required over frequent duty cycles.

At the mechanical interface, the motor can sustain 50.0 Nm of continuous standstill torque, so it resists load forces without thermal overload when the shaft is locked. Mounting accuracy is aided by a centering diameter of 180 mm, while the square flange measures 192 mm to match common machine frames. Position information is returned through digital servo feedback (HSF), providing high-speed signal cycles for tight control loops. Heat generated in the stator is removed by natural convection, so no external blower or liquid circuit is required. This cooling method keeps the installation simple because there are no separate moving cooling parts to route or maintain.

The electrical leads terminate on a power connector that is oriented to the right, allowing cable routing along a consistent side of the machine bed. A sealed housing protects the bearings, and the shaft seal helps limit contaminant entry from the surrounding environment. The rotor uses a plain shaft that mates with couplings or gearboxes without keyways, which helps reduce stress concentrations under reversing loads. Position is reported as relative rather than absolute, so the axis is referenced during startup before normal operation begins. Winding code 024 indicates the electrical resistance and inductance used by the matching drive, and it is paired with frame size 115 and length code B to support the motor's torque output within its overall package depth.
