I have the following synchronous motor ripped out from an old range hood in my kitchen.
I used new electrician tape to cover up the coils that should form the electromagnet--the old cover is too oily. From wikipedia I know it works by inputting alternative current to produce a rotating magnetic field to drive a rotator made of permanent magnet (the grey thing I partially removed from the stator). But the videos that explain synchronous motor doesn't use a motor similar to my own. Can you explain to me how my synchronous motor works?
Also, can I input DC into the red and blue wire and use this as a electromagnet that produce a field in the iron core as shown by the blue arrow?
