Product Description:
The MHD115C-024-NG1-RA belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. Classified as a servo motor, it is selected for axis drives that need closed-loop speed and position control in industrial automation cells. The motor integrates a relative position encoder to relay rotor angle to the drive, allowing coordinated multi-axis motion without mechanical backlash compensation.
This model develops a continuous standstill torque of 70.0 Nm, and the holding brake is rated for the same torque so loads remain fixed when power is removed. A flange diameter of 192 mm mates to machinery frames, while the 180 mm centering recess aligns the housing. The enclosure carries a IP65 rating, guarding the stator against dust and water jets; heat leaves the frame by Natural convection, eliminating external cooling hardware. Rotor feedback is delivered through Digital servo feedback (HSF), which the drive interprets in high-speed control loops. Mechanical dimensions are defined by motor size 115 and length code C, and the electrical build follows winding code 024. Power enters through a right-side power connector, simplifying cable routing inside cabinets.
Accuracy at the load flange is specified at ± 0.5 angular minutes, helping maintain synchronized paths in gantry and transfer systems. Storage temperatures from -20 to +80 °C protect insulation during transport, while rated operation occurs between 0 and 40 °C. The Class F insulation system supports winding temperatures up to 155 °C, and installation is allowed up to 1000 m above mean sea level without derating. Position information is captured optically, and the encoder reports relative counts to the controller. A Plain shaft transmits torque without keyways, sealed by a dedicated shaft seal to block lubricant egress. Combined, these characteristics permit precise drive integration when compact natural-cooling servomotors are required.
