Hi I have running off a inverter a Electrodrives Ltd induction motor.with 2800 rpm.labeled as A1pak11 , iec 34-1, the terminals are marked as V,W, U and N. This works fine with forward reverse and jog. However I now want to fit this to my Myford S7 but physically it is too small. I do have a Crompton Parkinson motor which is marked as0.5 hp , 1425 rpm, volts star 380/440, amps star 1.0 volts mesh 220/250 , PH 3 with terminal A B C and N. The 3 wires ( plus earth) from the inverter seem to be marked wire as wire 1, 3, and 4. Wire1 going to terminal U. wire 3 going to V and wire 4 going to terminal W. So can I use the Crompton Parkinson motor and how do I connect it up . all help welcome. Mike
Help with swapping motor

Look inside the electrical connection cover. You should see 6 terminals usually two rows of three. There should also be three metal straps.
Fit these to join each terminal on the top row to the nearest one on the bottom row. Take three wires one from each strapped terminal pair and connect to your inverter. Ensure you fit an earth wire too. Switch the inverter on and check the motor runs in the correct direction. If it does not, swap any one pair of wires between motor and inverter.
Job done.
