In this setup I found that the motor would speed up when I connected gen. 2 to input of b-2 ( 3 phase bridge rectifier). Without gen. 2 connected the .25 hp motor draws about 360 watts. 195 watts from gen.1 and 165 watts from variac. When I connect gen. 2 in circuit motor speed increases and motor only consumes 180 watts. 80 watts from gen. 2 and 100 watts from variac. I also noticed that the windings of gen. 2 don't seem to heat up but gen. 1 does.
The generators are bldc motors with commutation modules removed that I am using as a basic 3 phase generator. Gen. 2 does not have a motor turning it and since it has no module the rotor just locks up in one position.
Both gens are identical.
Long story short why doesn't gen. 2 load down gen. 2 even more. Also why don't gen.2 windings heat up. The frequency of gen.1 is 195 hertz at 88 volts when gen. 2 is not connected. 200hz and 86 volts when gen. 2 is connected. I know it seems pointless but please indulge me.
