I have a bearing on the front out put shaft clicking so I contacted the company and they told me 1 year over the counter free replacement. Here is my dilema as I talked to them I asked if I could pay the difference and get a 1.5 hp instead of getting the same 1 hp I have now they said no problem . The same company same motor but 1.5 hp ac motor can I get a VFD that would work for me on this motor ac current the VFD being AC as well . I dont know really to much about this please fill me in how much and where from I only have 1ph in my house.Another small problem might be the 1.5 hp has a draw of 15 amps the same as my breaker but I think I could change the breaker to a 20 for like 10 bucks so I dont think it would be a problem or would it ??? kellyw
 
Most VFD's convert single phase to 3 phase. But, they usually require 220 v input, and put out 220v.

I'm interested in the answer to this question because I'm in the same boat. I bought a 1 HP motor for my grinder because I thought the 1.5 would trip my 15 amp breaker at peak loads and that might shorten the life of the motor. I could have afforded the 1.5 HP at the time.

I know others say they don't need more than 1 HP but I do. I bogged it down today trying to thin out some aussie burl blanks on the platen.
 
just email me and I can help anyone of you. I have done it before and used to work with this type of motors and converters ac and dc.
 
If you find that you can increase your motor power, I would highly recommend it. I have a 2hp motor driving my KMG right now, and I have managed to bog it down (somewhat) with some heavy stock removal.

I'm sure that a 1.5 hp motor would be much better than a 1 hp (well, 50% better, to be exact).

If you have room in the breaker box, a 220 breaker is not hard to add.

I had a 220 20 amp breaker/outlet put in recently for my new knife kiln. I can't justify the cost right now but think I'd rather upgrade to a 2 HP next year and make a special extension cord from my new outlet to my grinder.

I just wondered if I could have bought a 1.5 in the first place and run it on a 15 amp breaker.

Would there be any power loss with a 40 foot extension cord if I used the appropriate guage wire?
 
The motor im looking at is a 1.5 hp , 1 ph , 230/115 volt will it work on a vfd . This way i can run it 115 till I get a vfd and then rewire everything.
 
Don't just change your breaker! you will burn your house down if 15 amps was the proper match for the wire and you switch to a 20 amp breaker and draw more than 15 amps. If your breaker is 15 amps it is a good bet that the wire is 16 gauge, and the outlet is rated 15 amps. Electricians will not generally spend the extra money for 12 gauge wire unless they have to. Put in a new breaker and run brandnew 12 gauge wire from the box to the shop. While you are at it install a new GFI, and make sure all of your grounds are good

What SUNSHADOW said X2 ++++

Do not just replace the breaker! You have a wonderful family, not to mention that you are a good customer and your insurance would probably be void. The breaker, the wiring, the outlet and the plug/cord should all be changed.

You should not exceed 80% of rated load on a circuit - ie 12 amps on a 15 amp circuit.
