i haven't taken one of the newer ones apart, so don't know what they are like now. The last one I took apart was from a GM truck, a 2009, and it still had the same 12 claw rotor. After doing some thinking on this if they are changing the rotor pole number they have to be doing something with the stator winding pattern too. A less distributed coil pattern would be needed to work with a higher rotor pole count, and it has to still be three phases. Unless they also changed the rectifier circuit too.
