AIR403 vs AIRX Stator wiring

[dconn]

Hi All



Does anyone know which coil endings on a AIR 403 stator relate to which endings on a AIR X stator?  both have 3 1/2 mm ring connectors but the AIR 403 has four connectors and two of these connectors have two wires while the other two have one coil ending wire each while the AIR X stator has three connectors, each with two coil end wires each.  The four connectors on the AIR403 stator are colour coded: Green, Yellow, While & Black while the AIR X stator connections are numbered 1, 2 and 3.



AIR 403 Stator:

Green: 2 wires

Yellow: 2 wires

White: 1 wire

Black: 1 wire



AIR X Stator:

# 1: 2 wires

# 2: 2 wires

# 3: 2 wiers



I am interested to see if anyone knows which colours on the AIR403 wires match which numbers on the AIRX wires.  I'm guessing that two coloured connectors on the 403 stator should match one numbered connector on the AIRX layout.





Thanks for any information.

The 403 and the AirX have different windings . The 403 is wound open delta with a different turn count on each leg. The AirX is probibly  wye wound. The control scheme is completely different so there is no match of connections.

Thanks Victor,



I was wondering about this.  I did think that the AIR403 was a delta with a broken corner (thus the two leads with only one coil wire each) - and the AIR403 does seem to have three different wire sizes on each phase (so the different turns too I suppose).



But whats funny is that the three AIRX wires all seem to have two wires in each - so maybe its DELTA rather than WYE (STAR) too?



Thanks

 Your probibly right or it could be a parallel wye. I don't know if Southwest uses different stators for the different voltages of AirX turbines, or just uses different connections of the same windings as they do on the Whisper series.
