Single Phase cap start cap run with VFD
(OP)
I have an application with two single phase cap start/ cap run motors.The control gear is shot and the customer wants to up grade using single Phase vfd,s. Has anyone done this before? Regards

But some submersibles from European or Asian suppliers are actually 3 phase motors and their N. American sales divisions give you a static phase-adder panel with them for derated 1 phase operation. Check the pump manufacturer on that one, but be aware that if you now use them as 3 phase motors with a VFD, the HP may be higher than you thought it was, meaning a larger VFD than what the 1 phase nameplate may indicate.

(Yes, I have been involved in that company, if you ask. But I left the board four or five years ago, so I think that it is OK to tell you about them now).
Go to http://www.nfodrives.se/ and click the English flag. These inverters are the only ones that are allowed onboard stealth vessels, because they have lalmost no emission and the acoustic noise from the motors is nil.
