I have a question that's been bugging me for the last few days. One of the things that I find interesting about the sg motor is how the input power reduces when it is loaded, which is opposite to the conventional motor behaviour. Having watched Electric Motors Secrets I deducted that it was because there was no back-emf or at least much lower than usual. But if I use a reed switch to trigger the transistor instead of the trigger coil then that effect is lost and the input current increases under load. I would like to know what is the difference in these 2 ways of triggering that creates so different results.
