Electric ac induction motor 50hz to 60hz?

[Poolworx]

Can a single phase single speed 1.5hp induction motor run on both 50 and 60 hz 115 volts

Something like this.
Ebay UK number 265213284360
Slightly more than £50 but best going slightly more on the kw rating

Thanks Fazz711

Unfortunately it doesn't ship to usa however I found a similar one but it says "The input for this VFD is 1 or 3 phase, and the output is 3 phase. Should I be looking for one with Single phase output not 3 phase

This is the spec for the one I found

Yes look for single to single.
Either that or look for three phase pump.
Which would be more efficient.

I have never come across a decent single phase to single phase speed controller

if I was doing it, I would be Looking for a 3 phase motor and a single phase to 3 phase inverter

I could then buy a decent quality system and not have to worry about the effects of capacitors and how they interact with a vfd drive.

That would be the way I would do it.
Three phase pumps are better quality and more efficient.
But you have to factor in the cost of new pump if you allredy have a good one.
Proper single phase to single phase are good enough to run a pump.
I understand not using cheap speed control they very rarely work well unless you spend decent amount on them

Forgive me if i butcher this but if the input voltage is 220 volts 50Hz and the output is 3 phase, im assuming the output voltage is 220 volts across phases and 60Hz. Could i not then feed the motor from 2 of the phases

No don't think so as the unit will see an imbalance and shut down
