I have a motor at home, it's a soviet era motor. It's connected to what seems to be a capacitor.
The setup pretty much look like the following one except the red box is much larger than the one on the picture and I can't see the markings. The one on the picture is 2uF 10% for 400v.
I was wondering if there was a particular reason why the capacitor is so big. If it's just that now capacitors for the same specs can be much smaller than the ones in the 70s.
Also I don't really understand the wiring of the motor. Mine is wired pretty much the same way except I have a switch that lets me change the rotation direction. I can't tell much for now as I'd have to dismount everything to access the readings to get a better idea. What I can tell is that this is a 127v AC motor. Here are the markings:
127v 30hz 6w
To my understanding, the capacitor is used to somewhat limit the current to something around 127v. So tecnically, I could replace the beefy capacitor by one of same value that I gather from broken fluorescent/led lamps?
