The field winding current is set to produce rated stator voltage of 150 V (lineneutral rms) under opencircuit conditions with rad/ s. a) Determine the maximum power that can be obtained from the machine. (6 pts) b) If the qaxis damper winding is open (rather than short) circuited, determine the steadystate voltage that would be observed across the damper winding at the maximum power condition.
