Have been toying with different vsd's to run my Town Woodhouse, maybe will run two motors from this:
It's a rather old Siemens, pulled it and the control panel out of a skip years ago, tested it, it worked with an extract fan I wanted to use so I put it to one side.
I'd had a look inside it, my feeling was that it might pop some of its supply smoothing capacitors, but today I thought I'd test it.
And pretty much, every one of those white blighters went bang. I let the smoke subside, pressed go and sure enough the drive ran. Then tripped. I'll have to check but I guess it was undercurrent - the motor is only 1kW, the drive is 2.2...
I have a manual, so will buy some caps and see if it will reset and run.
