I have a bit of a problem correctly wiring up the motor on a piece of industrial equipment that was ordered from China.
When ordering I was told that it would run off of a three phase supply. I've attached a picture showing the label with the wiring diagrams (supposedly for clockwise and anticlockwise operation) attached to the motor.
The label shows two wiring configurations. It was wired up in the first (clockwise) configuration when it arrived. Both of the configurations seem to expect a single phase supply and use two external capacitors.
The second one quite clearly just shorts the supply. The first one is less obviously stupid, but does not look like any motor wiring scheme I have seen before. But when i connected it up, the motor ran for a few seconds before one of the capacitors (rated for 450 V/AC) started smoking and the breaker tripped.
Can any one explain whats going on here and maybe give me some advice on how to wire it up correctly? Any help would be greatly appreciated!
