When I went for my first jab, my expectations were based on injecting sheep with a blunt needle, which made me a little apprehensive, so I looked away when having it. Was a bit of a pleasant surprise when i hardly noticed the needle goung in.
3 phase is normally 400v which is how the motor has been wired to run, but when you run an inverter from a 230v single phase supply you get 230v 3phase out, which means that the motor would only run at 2/3 of its rated power. By rewiring to delta it will run on 230v 3 phase at its full power rating.
You need to re wire the motor to Delta. With the three lings going in parallel, and a red wire connected to each as per the diagram in my earlier post. If it turns the wrong way afterwards, swap any of the two red wires over.
You could buy a tacho off ebay and measure the speed? Non contact or contact type cheap enough off ebay.
Can you put up pictures of the motor rating plate and of the motor terminals and find out what the following parameters are set to Input AC supply voltage
Maximum output frequency
Maximum...
Is the motor 230/400v? And do you have it wired in delta?
What does the drive display when its running?
Have you set the motor rated current and frequency to 230v and 50hz?
Also the part number in the description is for a 3 phase 400v drive, is that correct? I'm not familiar with that...
Its not single phase, its dual voltage, which means it can run on 230v 3 phase or 400v 3 phase. You could run it from a single phase supply using a variable speed drive wired as 230v single phase.
The costs soon add up, vending machine, building/hut for the machine, pasteuriser, building for the pasteurizer, milk cooling, transfer pump, vehicle to transport the milk if on another site, marketing, e.g. signs etc.
Maybe Dwr Cyrmu can point you in the right direction? They were taking unwanted pesticides etc for free, no questions asked, but doubt they will take a few IBC's 😂.
If one side of the DC circuit is grounded then I cant see why you couldnt have earth leakage in a DC system, and I cant see why the fault couldnt be traced with an insulation resistance tester on a rainy day, just in the same way as you would in an AC system.
