Hello friends, Today I put the motor on the lathe with a
single turn, single coil
in 8-10-12 format (No.20 SWG) and the results were like this.
RPM --- Open Volts AC
210 --- 0.31 V
350 --- 0.50 V
540 --- 0.77 V
765 --- 1.05 V
According to this at 140 RPM (cut in) I would be getting
140 --- 0.20 V (Computed value)
Now how do I compute my final coil turns from this
single turn, single coil
. Is it simply like
For 14 volts I would have to wound it with 70 turns.
0.20 V x 70 turns = 14 Volts (coils connected in parallel Delta).
For 24 volts the coil can be connected in series delta or parallel star.
I know there is something like 1.73 times but didn't understand it fully.
