I posted this on a machininst forum and got no straight answer. Maybe I just posted it in the wrong kind of forum.


Next, lets make a "hypothetical" situation to solve.

Lets say ya have a wall that has 220v single phase power, then sitting on the ground under the 220v outlet plug on that wall, there is a new drum switch and a 220v motor. You also have a roll of the correct gauge wire sitting there with it along with the necessary hand tools and wire terminals and ya want to make this motor turn using the power from the wall



How would a qualified electrician make this happen? we know that 3 wires with a plug on one end (one white 110v, one black 110v and a green ground wire will be supplying the power. That's Line IN.

We know that the motor has 5 wires proceeding from it as follows

they are labeled

PE = green/yellow (ground)

U1 = black

U2 = brown

Z1 = black

Z2 = blue

We know that the drum switch has 6 terminals that wires can be connected to (plus a threaded hole for a ground wire.





What wires need to be attatched to where to make this motor turn forward and reverse?

If the motor is labelled " and a 220v motor." The electrician would first check the frequency. This may be a European motor intended for 50 Hz.
It may be an oriental motor. Questionable quality but if it runs, it runs.
L1 to 1
L1 to 5
U1 to 6
L2 to 4
L2 to U2
Z1 to 2
Z2 to 3
PE to ground
