Powerful super efficient AC Synchronous motor to power up 220 volt bulb
An interesting motor from Microwave oven - it's the AC Synchronous motor rated at 220-240 volts @ 4 watt. This stuff can power up an LED bulb rated 220 volt @ 3 watt brightly with just a small turns. This motor is a good idea for energy harvesting from mechanical means.
One simple circuit to step up voltage using LM2577 -Adj P+ chip. The schematic is from Texas Instrument and it works expected - and below is...
