Hi folks, I am a little bit confused on the conversion of torque to electrical power. specifically i have a rotor stator combo I've been looking at from a snowmobile (photo below) and I simply do not understand it. I know it has multiple different turn ratios on the bobbins for different purposes which they generate higher voltages. About 6 of the coils are called the lighting coil which generate the power for the 12 V system on the machine. What i dont understand is how the torque load on the engine will ever change with this type of configuration. As the rotor (with its permanent magnets) passes by each of the coils it generates a voltage depending on the strength and the speed of the magnetic field dictates the amount of current i think... Either way regardless of how much electrical load is "requested" outside the stator, the stator should impose the same torque on the rotor or so i thought. when i load down the generator the whole system makes a chattering noise which tells me the electrical load is created a larger torque load. Can someone explain how this works and show the equations to how a system like this might function?
