hello again.
today I was back at the motor,
the voltage is only around 220v at the starter. during starting this can drop to around 212v, during running its is around 218v.
everything has been ok since i was last there, but i am told the mill/bruiser throughput is less than with the previous...
hello again. yes that all makes sense.
i have added the the contactor connections to my drawing of how the motor is connected just now.
I'm back at work today (at my real job) for 5 days so I wont be back at the motor until next week. i will get some accurate voltage readings at stop, start and...
Marconi.
Today i rearranged the cables almost identical to your drawing. However i ended up using the starter to switch the neutral as cables i have coming from the motor didn't allow for exactly what you have drawn.
the cable Z goes from the capacitor and straight into the motor. I have...
Evening guys. I had replied last night but cant see my post anywhere. Dont know whither it went on or not.
Just for info this starter and motor were used together it started and ran without issue. Since then they were disconnected and not marked so i thought the problem to be a wiring mixup but...
thanks for the advice, the supply is just single phase live and neutral on a TT earth 230v and neutral. this motor did run last year at a neighbouring farm on a single phase live/neutral supply. i know this for a fact as i connected the supply into the pre wired starter motor setup early last...
thanks for the advice.
i had a very quick look today. i removed both capacitors and tested them, both appear good. they are marked 690-850 uF one is reading 770uF and the other 740uF.
i have made a rough sketch of the cables markings from the terminals going into the motor on the left and on...
just to put everyone's mind at ease this was all very temporary and i have rewired from the starter to the motor alot better than what is shown. the motor defiantly worked last year on a single phase supply, and has since sat in a shed.
hi,
I am new to the forum, apologies for replying on an old topic.
I have been searching for info on series parallel single phase motor starting,
I have a job of replacing a 10hp single phase motor on a grain mill. the old motor had been removed and the new one (new one is also an antique)...
