MHD090B-047-NG1-UN

MHD090B-047-NG1-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 housing uses natural convection to dissipate heat without a powered cooling fan, while class F insulation provides the motor’s thermal insulation rating. The operating ambient temperature range is 0 to 40ºC, the storage temperature range is -20 to +80ºC, and the maximum setup height is 1000 above mean sea level.

The digital servo feedback encoder uses high-resolution servo feedback (HSF) to provide relative position detection. Its optical measurement method reads position without mechanical contact, and the system accuracy is ±0.5 angular minutes. Power and feedback connectors carry electrical power and encoder signals, and the power connection can be turned within a 270° range to accommodate cable routing.

The motor has a plain shaft for direct coupling and includes a shaft seal to help prevent contaminants from entering around the shaft. Its holding brake supplies 11.0 Nm of braking torque to hold the shaft when motion is stopped. The flange size is 140 mm, and the centering diameter is 110 mm for installation alignment. An IP65 degree of protection makes the enclosure dust-tight and resistant to water jets.
