If you have 1 bobbin of .2mm that would give you a slight increase from 60.8 to 62 CM. I wouldn't change the turns.

When you break the connections, make sure 1 has continuity with 4, 2 has continuity with 5 and so on.. In other words, 1 would be the start of the group of coils, 4 would be the finish. No, follow the drawing.. This drawing is to bring out all 9 leads. The connections listed is for the...

Drawn on paint hope it will help..

2 wye connection. Could be 440 or 220. Normally, we'll mark the voltage on the nameplate when we rewind them to 3 leads. If you want 9 leads, take it to a motor shop. They can determine if you need 1-2 wye, or 2-4 wye.

I spotted a mistake in my first two drawings. It was late when I drew them out.. This should work for a 2 delta PWS with that coil configuration. zlatkodo, please double check.

A phase =black b phase =green c phase = red 6 groups of 2 6 groups of 1 2 delta PWS sorry for the bad paint shop job..

1/3, 2/3 only on a 6 pole.

Looks like a pole connection. Please post all winding data, IE: Total number of coils. Wires in hand, wire sizes, number of wires to each lead, number of turns, number of total wires in slot. Coil pitch (span). Iron dimensions: Length, tooth width, back iron(iron below slot), bore diameter...

This might help Regards

Each number represents a group start and finish. Glad I could help.

That's a 2 delta PWS. According to the name plate and schematic. Here is the connection diagram to rewind this motor.

Could be interpole polarity. Mark and shift brush holder ring out of neutral point. Take a 12 volt battery charger and flash A1 and A2. The armature should "kick" in the same direction that you shifted the brush ring. If it kicks in the opposite rotation, switch the brush holder leads.

We use the Lexseco core tester, with the green magnetic paper. Works well. Sometimes we have to heat the rotor up to 400F before it shows opens. Rotor testing can be tricky.

I've wound two coil interpersed. Never four. Can someone explain the jumpers? Is this to control circulating currents? Saving this connection for future reference.
