Hello!
If I want to use larger router bits in my router I have to reduce the speed but the problem is that there is no speed control at all. So, I want to build some kind of external speed control. The router is powered by universal ac brushed motor. It runs on 230 V mains voltage and has a power of 1650 Watts. So triac chopper should to the trick, but without some kind of speed fecback it will be useless. In my other smaller router there is a magnet and an induction sensor which is connected to speed controller probably based on triac circuit, so the speed is constad, of course if the device is not overloaded. I searched over the web and it's realy hard to find schematics for AC brushed motors. I finally came along this. Will this work if I adjust the components values for my supply voltage and power of a device, what about the speed under load?
Thank you very much, and feel free to post other suggestions and schematics.
