3 phase hoist to single phase, can it be done?

[vonsmog]

I picked up this hoist for next to nothing on CL. Would like to convert it to single phase if I could. If not i will post it on Ebay and make a profit. I do have a use for it, but I don't want to spend a ton of money for a phase converter, would just like to make it work with single phase. Anyone know if its doable?
Thanks, Von

Change the motor?

What horsepower is the motor? The best device out there for converting from single phase 220V to 3 phase is the Variable Frequency Drive! I have one for my mill and I can adjust the spindle speed using the VFD.

A VFD for a 2 hp motor goes for about $160. Very easy to install.

I have one of these to run my 3 phase mlling machine off of my 220 single phase shop wiring..... Simple to wire and works perfectly.

Mine is the 1-3 hp model like shown in this link, but they offer one size smaller for up to 1 hp motors.

Here it is on the Phoenix website, but they sell them on ebay also for a bit cheaper with free shipping which is how I bought mine a couple years ago.

1 HP to 3 HP Static Phase Converter

If your motor is 1hp or under, you should probably get this one for $59 on ebay w/ free shipping.

Rotary phase converters or VFD's work great also, but for a simple motor with no complex electronics or computers, the static units that I linked to work just fine. IOW, the static converter works fine for my simple mill, but would probably not work properly on my CNC mill. When I get around to getting it going, I will probably have to get a rotary phase converter.

You can also use a three phase motor with no load as a rotary transformer. An old junk 3-phase with a higher horsepower rating. You have to pull start it before you use it.

Sounds like a perfect application for a retro encabulator to me.

Thanks for the link for the phase converters! Since the motor is only 1/2 HP I got the one for $59.00 off of ebay! Just hope it works now! Thanks again, Von

cant you add a capacitor to one of the legs of the 220 for the 3rd phase?

That is basically what the static phase converter does.
