Tried a F&P 36 pole aluminium stator today for the first time just to check how it compares to a copper version.

Results were 615 W at 588 RPM on my crude test rig. Other reading are 410 VDC and 1.5 Amps into my controlled current load. This is about 7% less output power than the copper stator.

Open circuit volts reading is about 1.1 VDC per 1 RPM. Copper stator is around 1.185 VDC per 1 RPM. This implies that there are less turns per pole. The resistance reading phase to phase star is 38 ohms vs 32 ohms for the copper stator.

It's possible to get a good output from them but rewiring them becomes a challenge. Solders used for aluminum generally contain zinc with some lead, cadmium, tin, copper, or aluminum. However, any solder that contains tin may cause an electrochemical corrosion problem due to its galvanic potential.

Well not exactly the one outlined in this topic is a 36 pole aluminum stator using a 48 magnet black rotor cap. These are used on all top loading washing machine currently in production.

The FP640 stator that you have is a 27 pole aluminum stator that uses a 36 magnet black rotor cap.
