Hello, I am please to meet your acquaintances! I registered for the following problem: The system at hand is a motorcycle charging system with a permanent magnet alternator and a shunt rectifier. The common belief is that the regulator/rectifier (R/R) dissipates all surplus power. I think that it does not, that all induced current does not flow but instead some is stored in the stator, which would then provide some back-torque. I have devised an experiment for this. Run the bike at a fixed rpm. Put an ammeter on the stator output and measure the current. Now turn on additional electrical accessories. Re-measure the stator output current. If the current increases, then current is stored in the stator and the R/R is only dissipating some or a fixed amount of surplus power. If however the current out of the stator remains flat with additional system load, than the stator is always supplying 100% of its current (and power), and the rectifier is always dissipating all excess power, as is the common belief. Lastly something that is foggy to me: I think that the induced current is only a property of the stator physical makeup and rpm, and any control from the regulator/rectifier does not affect the induced current. If loading the electrical system alters the regulation, which alters the induced current, please tell me. If I am missing something, I suspect it may lie here.
