All m/c generating AC power supply in the universe except
battery.in the gen. we apply dc power on rotor which r
short ckt at ends(some times on stator also),that create a
magnetic field on rotor name north & south pole.as rotor
rotate than the magnetic field north pole cut by stator
conductor that produce +ve half cycle.as rotor move north
pole magnetic field cut by stator conductor,that create -ve
cycle.so in this whole process we get ac.The function of
the
commutator to convert ac into dc,becouse commutator is a
mech. rectifier.

what is efficient motors and how it is different from normal induction motors
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?
