I referred to B measurement, because hall sensor have been suggested in the discussion. But you hardly get an integral flux measurement using hall sensors. I'm not sure however, what you want to achieve.How can I measure the induction B, because it is heterogeneous for the whole claw?
It would be helpful to sketch the magnetic circuit and decide, which flux you want to know.Whether it must meet some requirements for the induction loop around the excitation winding or not, because the shape of claw is quite complex.
I don't know, it they are thin enough to fit the alternator air gap. An you only get point by point B measurements.can it use the Inexpensive magnetic flux (gauss) meter
Of course it does. The excitation winding generates a magnetical field H according to N*I, the induction B and total flux is defined by the magnetic circuit, particularly the air gap. Please refer to elementary magnetostatic equations. Magnetic circuit - Wikipedia, the free encyclopediathe stator can not change integral flux of claw
Yes, if it's varying between exemplars.Can gap B between the claws and the stator represent the claws performance?
There should be no big difference for the unloaded alternator. With load current, the flux may be reduced.Is the difference very large if we do not rotate the claws?
That's small. 0.6 mm hall sensors are still industry standard, e.g. Toshiba THS129.the air gap is usually very narrow about 0.25-0.4 millimeter
