Motors


2004/02/27. I got a rather awkward motor just for fun. It is a 3-phase 200V 200W AC motor (about 0.27hp). I also got a 750W single-phase 100V to 3-phase 200V inverter to power the motor. I haven't even begun to figure out how the inverter works, but the instructions mention all kinds of cool things like reversing rotation, feedback control, and ramp up programmability. Aren't online auctions great?!
2004/04/03. A friend came over and we wired up the motor. We plugged it in and hit the power button. Beautiful! The motor controller is really amazing. We could control the motor speed very, very accurately, feel constant torque, and change directions electronically. There's still a lot to learn, but I know enough now to make the motor useful. One of the biggest advantages is that I don't have to make step pulleys to drive the lathe. I can get by with a single pulley and use the controller to set the speed. This is especially nice because I don't have a lathe to make pulleys yet!
