Grinder Wattage for 220V to 110V transformer

by **mindless_fool** on Fri Feb 04, 2011 11:35 pm

I bought a VFA grinder for really cheap on kijiji (see pic below). The issue i have is thats its 220V and i live in 110V...i need to get a step up transformer but cant find out what Wattage i need. Would a 500W one be enough or do i need more, think the next level up is 800W. Below is a pic of the info on the back.

Volts x Amps = Watts so you need at least 418 Watts.

As it is an inductive load X3 to be safe for start up currents. Any less and you run the risk of the smoke coming out. :shock:

If you know of a local motor rewinder then take the grinder in and ask the question what it would cost to have it rewound to suit 110V. This may work out better on $$ and less junk in the kitchen.

If you can be sure you're operating at the 60Hz frequency, you could always wire yourself a 220V outlet. If your home only has single phase power coming in, you would probably get 208V, but 10% is an allowable variance, and you'd be within that.

i cant run a 220V line as im in a building with concrete walls. Rewinding could be an option, but I feel it could be pricey, i can get a transformer 500W transformer for $40. Space is not an issue as it isnt too big and would fit under my coffee bar...so if 500W is enough then i will get that...thanks for the input guys..

If you can access TWO separate 110V circuits, they can be combined to give you 220V.

If you have electric stove or build-in oven, it generally runs on 220V in the kitchen.

im in a rental for now and changing the wiring is a no no...wonder if I can somehow safely wire it to my stove plug just to see if it actually works before buying a transformer
