    Vfd 415 motor 240v supply.

    Hi, i saved a 5.5kw, 2 pole, 2850rpm, 415v, 10.2 amp motor from the bin at work, its wired delta.
    Can i run this as 240v 3 phase on a single phase vfd?
    Is this easy to match the vfd?

    Many thanks for reading.

    Are you sure it is delta, small three phase motors that use a 415v supply are usually wired star which would allow you to connect as delta for 240v three phase. Dave

    It does look like it is delta connected for 415v, it is probably designed to be used with a star delta starter. You can get inverters that will step up to 415v from 240v but they are pricey for a motor that size, they sell for about 1500 GBP in the UK. Dave

    Its a delta motor at 415 so sorry you shouldnt use it cause supplying 230v will cause much reduced torque. Best to buy the correct motor
