Single phase motor

[elmer phud]

Had a few probs with one. Sounded like a phase down. Checked centrifugal switch (full of crap) ran fine without load/gearbox. Put a 4"x4" timber on shaft and stood on it (18 stone) ran fine (load test) Lesson learned, I need to put weight on . Outcome-start cap U/S under working load, not fatty me. Centrifugal switch kicking in and out causing clattering... Took me a hour to sort this, what a dope! I hate single phase motors, especially in a shed with 11,000 hens!!!!!!

Single phase motor

''Sounded like a phase down'' if it had a phase down the would be NO POWER to motor at all?

It appears to me that single phase motor problems almost always end up being the capacitor

Most probs ive had tend to be due to excess mechanical load,only once have i come accross a dud capacitor and ive tested hundreds

I agree with Ian.
You may have just invented the first motor that can run volt-free, wow the tree huggers will be happy -

I think SOUNDED is a key word here

I don't know what a single phase motor sounds like with a phase down.
Simon and Garfunkel made a record of such a machine, but I can't remember how it goes -

'Sound of Silence' was it not.
