Product Description:
The MHD115C-059-NP1-BA belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Classified as a servo motor, it is used in industrial automation to generate precisely regulated rotary motion for gantries, packaging modules, and material-handling axes. The model uses relative position feedback so the drive can track incremental movement during closed-loop operation. That arrangement allows commanded motion to be compared with actual rotor movement so speed and position errors can be corrected during acceleration and stopping. It is also supplied with an integral holding brake for load retention when input power is removed.
This motor delivers a continuous standstill torque of 70.0 Nm, giving it high static load capacity without overheating at zero speed. This is useful on axes that must support tooling or process loads while maintaining a stable shaft position. The mounting interface includes a flange that measures 192 mm square and a centering pilot diameter of 180 mm, which helps keep the housing aligned with machine frames or gearbox faces. Rotor angle is reported through digital servo feedback (HSF), supporting high-resolution velocity and position control in the connected drive. The housing relies on natural convection, so no external fan or liquid circuit is required. A keyed shaft transfers torque to the coupled load, and a shaft seal helps limit dust or oil ingress. Cooling ribs correspond to motor length C, which balances thermal mass with installation depth.
Electrical power enters through a connector on side B, which can simplify cable routing when the drive is mounted opposite the load. That arrangement can reduce cable crossover in installations where the motor faces away from the drive cabinet. The frame uses motor size 115, so it matches mounting patterns associated with that housing size. Winding code 059 identifies the electrical characteristics used by the matching drive. This layout supports accurate servo operation in medium-power axes that require stable positioning and controlled speed response.
