MHD041B-144-NP1-UN

MHD041B-144-NP1-UN is a Bosch Rexroth Indramat servo motor in the MHD Synchronous Motors series. The motor is size 041, its length is B, and it uses winding code 144. It produces 2.7 Nm of continuous torque at standstill. The 82 mm flange and 50 mm centering diameter provide the mechanical dimensions required for mounting. Its keyed shaft supports torque transfer to the driven equipment, while the shaft seal helps prevent contaminants from entering around the shaft.

The motor uses digital servo feedback (HSF) for control-system feedback. Position detection is relative and the measurement method is optical, enabling motion to be measured from a reference position. System accuracy is ±0.5 angular minutes. Power and feedback connectors provide the electrical connections, and the power connection can be turned within a range of 270° to accommodate cable routing. A holding brake is included and supplies 2.2 Nm of holding torque to retain the shaft position when required.

The housing uses natural convection to dissipate operating heat without a forced-air cooling system. Its degree of protection is IP65, providing dust-tight protection and resistance to water jets. The insulation class is F. The permitted operating ambient temperature range is 0 to 40ºC, while the storage temperature range is -20 to +80ºC. The maximum setup height is 1,000 m above mean sea level.
