Product Description:

The MHD115C-058-NP1-AN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. In industrial automation, this motor works as an electromechanical actuator that receives command current from a drive controller and produces controlled torque for positioning tables, gantry axes, and rotary tooling. By integrating the feedback device with the drive, the motor supports accurate motion profiles that match the cycle-time requirements of automated production cells.

An important mounting reference is the centering diameter of 180 mm, which aligns the motor housing to the machine frame and helps minimize radial offset. The flange measures 192 mm, providing a mounting face that resists reaction torque during acceleration. When held motionless, the electromagnetic system can sustain a continuous torque of 70.0 Nm. Heat generated by copper losses is removed by liquid cooling, where coolant channels in the stator jacket stabilize temperature and support higher continuous output than air-cooled designs. Rotor position is captured by digital servo feedback (HSF), which delivers high-resolution signals for tight velocity and position control at the drive.

Mechanical power is delivered through a keyed shaft, and a shaft seal is installed to help limit coolant or lubricant ingress at the journal. Position calculation is based on relative measurement, so a homing routine is required after power-up. The motor uses winding code 058, which indicates the electrical characteristics used with a matching inverter. Power conductors exit on side A through an output connector, which can simplify cable routing on machines with same-side cabinet placement. The motor also has size 115 stator laminations, motor length C, and an integrated holding brake for stationary load retention.
