    Star delta motor issues



    Afternoon guys.

    Wondered if I could have some help please.

    Have wired up a new motor in the star delta configuration.

    connections at the motor are fine I believe.

    Now when motor is turned on main and star operate, then few seconds later, star kicks out and delta pulls in.

    The main is still in but now the motor stops.

    Any ideas as im going mad here thinking why?

    Many thanks

    Right. There's no voltage coming from the bottom on the contactor even though there is voltage at 1 3 5, just not 2 4 6.
    Coil has been pulled in but nothing going through. Assuming this is my issue.

    Always check a star/delta starter with a meter before connecting the expensive motor.

    Hi Brian.

    It’s ok I found the issue. On the delta side I had 2 wires wrong way round. No expensive bangs or anything so all good. Thanks.
