Product Description:

The MHD115B-024-PG1-LN is a servo motor manufactured by Bosch Rexroth Indramat in the MHD Synchronous Motors series. Within an automated machine, it converts drive commands from the controller into precise rotary motion and supports axes that require high dynamic response and repeatable positioning. Its built-in digital feedback transmits real-time rotor data to the drive, so closed-loop regulation can maintain commanded speed and angle even under load disturbances.

The motor sustains a continuous standstill torque of 50.0 Nm, allowing it to hold heavy static loads without overheating. A protection rating of IP65 seals the housing against dust ingress and low-pressure water jets, enabling installation on open factory floors. Internal coolant passages provide liquid cooling, and circulating fluid removes heat directly from the stator iron so thermal limits are reached more slowly during cyclic duty. Absolute position feedback over more than 4096 revolutions provides absolute (>4096 revolutions) detection, so the axis can return to its stored position after a power interruption without a homing routine. Combined with an optical measuring principle, the system achieves a positioning accuracy of ± 0.5 angular minutes, which helps reduce cumulative error in multi-axis assemblies.

The integrated brake can clamp the shaft with 70.0 Nm of holding torque, securing vertical loads when power is removed. During storage, the unit tolerates ambient temperatures from -20 to +80 °C, helping protect internal materials before operation. A centering diameter of 180 mm aligns the stator to the machine frame, and the 192 mm square flange fits standard ISO mounting patterns. A plain shaft eases coupling to gearboxes, while an F-class insulation system, a left-hand power connector, a positive shaft seal, and a permitted setup height of 1000 m above mean sea level round out the installation features.
