What are the factors that affect how much current is drawn into an AC induction motor?
I don't understand how a motor draws more current to start. I get why it would need more to start but I don't get why it would draw current into itself automatically. It may not work like that at all! But I could use a good explanation on this one. I am assuming that the power needed to saturate the core in the windings is greater on starting.?. How do you regulate how much power is delivered to the motor? If I plug a motor right into the socket(mains)of a 15amp circuit what is stopping the motor from drawing more or less or tripping the breaker? What is the power actually used for, I can see how there is power used up as resistance in the wire in the coils but how much power is used to saturate the iron cores(or ferrite whatever)? I have some knowledge of electricity but I need to fill in some blanks here.
I do have a few more questions on induction motors but I think there are enough for right now! Thanks
