MHD041B-144-NG0-UN

MHD041B-144-NG0-UN is a Bosch Rexroth Indramat servo motor in the MHD Synchronous Motors series. The motor is size 041, has length B, and uses winding code 144. It provides 2.7 Nm of continuous torque at standstill for maintaining torque at zero speed. The housing uses natural convection to dissipate heat without forced-air cooling. Its operating ambient temperature range is 0 to 40ºC, while its storage temperature range is -20 to +80ºC. The maximum setup height is 1,000 m above mean sea level.

The motor uses digital servo feedback (HSF) to provide position and motion data to the drive. Position detection is relative, and the optical measurement method reads movement without mechanical contact. System accuracy is ±0.5 angular minutes for precise feedback. The motor has no holding brake, so it does not mechanically retain the shaft position when power is removed.

The plain shaft provides a smooth coupling surface, and the shaft seal helps prevent contaminants from entering around the shaft. The flange is 82 mm in size, and the 50 mm centering diameter supports alignment during installation. Power and feedback connectors carry electrical power and feedback signals through separate connection functions. The power connection can be turned within a 270° range to accommodate cable routing.

The IP65 degree of protection prevents dust ingress and protects the enclosure against water jets. Class F insulation supports the motor’s electrical and thermal insulation requirements.
