SGMBH Sigma II - YAI
Rated Output: 22kW, 30kW, 37kW, 45kW, and 55kW
The SGMBH servomotor series had an internal permanent magnet (IPM) design which reduced rotor inertia. This servo motor was well suited for highly dynamic, high power applications such as hydraulic system replacement. There were 5 sizes from 22 kW to 55 kW providing up to 6,120 lb-in (700 Nm) of peak torque. 400 volt windings were available with rated speeds of 1,500 rpm and maximum speeds of 2,000 rpm. A 131,072 ppr incremental serial encoder was standard. Options included a 131,072 ppr absolute encoder, shaft seal, and holding brake.
The SGMBH Sigma II is a Legacy product and is no longer promoted in the Americas.
