Hi,
Newly acquired 120v Super 11 wishes it had a VFD.
Now as I've been led to believe, the 1 phase Emco actually uses 3 phase motors but has added run caps to trick the 3 phase motors into running on 1 phase. The wiring diagram looks like that's true but it's hard to be sure because of the complexity of the 2 speed motor switching makes it hard to grok. It is either a 3 phase motor tricked into two speeds and single phase. Or else it's a single phase motor with high and low speed windings.
The diagram definitely states a single phase motor. And the more I look at it it seems it could be a 1ph 2 speed setup.
Does anyone have knowledge on the topic?
So is a VFD just wishful thinking with this motor?
Thanks for your thoughts.
Patrick
