You're missing a few things
3- 3 phase AC into the stators that creates a rotating magnetic field
- By f-law, the changing mag flux due to the rotating mag field induces a current in the rotor coils
- By l-law, the current is in a direction such that the mag field it induces opposes the original change in flux the created it
- thus, the induced mag field interacts with the rotating mag-field and the rotor begins to spin as it 'chases' the rotating mag field
how much would this score if i wrote this as it is
