Answer Posted / arvind
you may be knowing about the equal area crietria, in this
as suddenly you disconnect the busbar from the alternator,
the rotor of alternator may lose the syncronism and
terminal voltage will be zero, and accrding to the relation
p=pm-pe, where pm is mechanical power and,
pe is electrical power
when pe=0 that means p=pm, it means only mechanical power
will be there.

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
