3 phase motor and VFD

mercredi 4 mars 2015

I have a CMG 3 phase motor 240v Delta, 415v star. Connected to a teco/Westinghouse FM50 drive, Single phase input to 3 phase output.

The problem is when connected in delta the motor hardly turns(set for 50hz ) and is very noisy. Wired in star the motor turns at correct speed but lacks power. Suggestions?
