What is an induction motor?How does an Induction motor differ from a regular motor?What makes it unique and why is the term Induction used? Thanks
this is an extremely technical question, isn't it? i visit project a guess: an inductions motor is produced from electrical energy, a wound motor is a hand crank. And a synchronous motor has a hamster interior.
What he did is not unusual. If you suspect someone else's work may not be good, then rip it out and start with all new parts which you join yourself. A sink with a hole in is very rare - YOU didn't notice it at first, did you ? My only criticism would be that the plumber should have checked his work out and noticed the leak then. You shouldn't have needed to call him back. What he mended is what usually leaks.
I would say that an induction motor is what you are terming as a regular motor. (Or do you mean DC) It works basically on the interaction of two magnetic fields. One field is produced by the coils connected to the supply, the other field is produced by the induction of current into the second windings by the field produced from the first winding. This second coil is known as a squirrel cage. This consists of copper or aluminium bars embedded in the rotor and short circuited at each end to produce the squirrel cage. However, this alone will not produce a rotor to turn. To achieve this you require to have a rotating, or moving magnetic field, or at least two magnetic fields which are out of phase with each other. See the link below which may help you more than I can here.
