Product Description:
The MHD115C-058-NG1-BA is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for industrial automation where electrically commutated drives must position loads with high accuracy and stable repeatability. A plain shaft supports direct coupling to external drive elements, while a relative position encoder that uses optical measurement supplies the motion data needed for closed-loop control. The HSF digital servo-feedback format allows the motor to work with compatible drive controllers for accurate speed and position regulation during continuous machine operation.
At standstill, the motor supplies a continuous torque of 70.0 Nm, so heavy inertial loads can be supported without forced cooling. The housing is sealed to IP65, which helps block dust and water jets commonly encountered on production lines. Operation is permitted within 0 to 40 °C, making the motor suitable for typical industrial ambient conditions. A centering diameter of 180 mm and a flange size of 192 mm help align the motor accurately on machine frames, while the system accuracy of ± 0.5 angular minutes keeps positional deviation low in coordinated axes. Power is connected through a connector on side B, and winding code 058 sets the electrical characteristics expected by the matching drive.
Heat is removed by natural convection, so the motor can operate without added fans. The windings use Class F insulation to withstand elevated internal temperatures during sustained operation. A holding brake rated at 70 Nm locks the rotor during power loss, and the shaft seal helps limit the entry of contaminants around the shaft area. Storage from -20 to +80 °C and installation up to 1000 m above sea level allow the motor to be used in standard plant environments as well as higher-altitude locations.
