chinese 500w spindle wiring

[john swift]

as I can not read Chinese either

I would check to see if the fuse is connected to one of the power terminals
if it does as I would expect that will be the Live (hot) terminal

I notice that there is no Earth terminal ! - a feature of many Chinese tools

at the very least I would connect the the mains Earth to the metal enclosure

PS Clive beat me to it !

hi. thanks for replies. I have got power to the spindle using the power unit that came with the spindle as per pic. but I can only get it to work when it is the only item in the power change. I have tried to power it from the machines mains input socket but know joy. it will only work if its the only unit. I am not great with elecs and I was hoping to just have the one mains plug socket to the machine. is there something I am missing here. I am only using live and natural feeds to the spindle power unit as there are only two inputs. the machine also as earth connected at the mains input. do you think that if I fitted a terminal block from the machines mains input socket and then to the two cnc driver power units and also the spindle power supply unit it would work.

I think you are in dangerous ground here.

Show us some good pics and a sketch of what you are trying to do.

Yes please be careful !

Sounds like you might have wired them in all in series ? They need to be in parallel.

Based on what you have written I would say get someone experienced over to see it first hand before fiddling any more

Also they are live and neutral not natural
