MHD090B-047-NP1-UN

MHD090B-047-NP1-UN is a Bosch Rexroth Indramat motor in the MHD Synchronous Motors series. The motor is size 090, its length is B, and the winding code is 047. It produces 12.0 Nm of continuous torque at standstill. The natural-convection housing dissipates heat without forced-air cooling, while Class F insulation provides the motor’s thermal insulation classification. The operating ambient temperature range is 0 to 40ºC, the storage temperature range is -20 to +80ºC, and the maximum setup height is 1,000 m above mean sea level.

Digital servo feedback (HSF) provides relative position detection using an optical measurement method. The feedback system has an accuracy of ±0.5 angular minutes for position measurement. Power and feedback connectors provide the electrical connections, and the power connection can be turned within a 270° range to accommodate installation routing.

The keyed shaft supports torque transfer through a mechanical key, and a shaft seal is included to help prevent contaminants from entering around the shaft. An integrated holding brake supplies 11.0 Nm of holding torque to retain the shaft when required. The motor has a 140 mm flange and a 110 mm centering diameter for mechanical mounting and alignment. Its IP65 degree of protection provides a dust-tight enclosure and protection against water jets.
