Timeline for Is there any way to wind this 4 pole motor to behave as 2 or 8 poles properly?

In that way I could have the same current produce the double of the field in them. So I could make a similar scheme of that you made but swtiching the groups, using 1 to 4 in the place of A to D and vice-versa, plus using all cores from A to D with the double amount of turns, in some way to increase design voltage. | |

Is that correct? | |

Stil a waste of effort except for the learning process.. now get a new washer motor from the dump and make a VFD for a lathe using DC to sine /cos synth Constant V/f | |

| Aug 24, 2020 at 5:12 | comment | added | user2934303 | Just a question: When a current flows in the same direction in any two coils in this diagram you made, does this mean those coils will be producing the same pole? Just asking cause in my diagram for example, a current going from A to A' produces the opposite pole of a current going from B to B', cause I always used the prime to refer to the inner leg of each core (but they're wound in different directions). | |
