Product Description:
The MHD115B-024-NP0-AA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Intended for closed-loop industrial drives, it delivers commanded rotation so that machine axes reach and hold programmed positions with high repeatability. By pairing with a drive controller, the motor forms a compact actuator for automated packaging stations, gantry robots, and metal-cutting centers. This type of arrangement lets the control system correct speed and position errors during operation, which helps the axis follow programmed motion profiles with stable response.
The motor mounts through a 192 mm square flange, while a 180 mm centering diameter helps keep the motor and driven load in coaxial alignment. A continuous standstill torque of 50.0 Nm supports high holding force without overheating, and the IP65 enclosure helps protect internal components from dust and directed water. Stator heat is removed by natural convection, so no fan or liquid cooling circuit is required. Rotor position is measured by digital servo feedback (HSF), which uses an optical track for relative position evaluation. Electrical power enters through an output connector on side A, and winding code 024 matches the electrical characteristics used with MHD size 115 drive combinations.
The motor is rated for ambient operation from 0 to 40 °C, with storage permitted from -20 to +80 °C, and it can be installed up to 1000 m above sea level without derating. Insulation class F supports the winding temperature rise that occurs during cyclic duty and repeated load changes. A keyed shaft transfers torque to the driven machine, and the integrated shaft seal helps limit lubricant loss and contaminant entry. Because the motor does not include a holding brake, static load retention must be provided by the drive or by external mechanical means. Position repeatability is supported by a system accuracy of ± 0.5 angular minutes, and the length code B housing keeps the unit within the dimensional format used for adjacent frame lengths.
