does anybody know where to get the vfd motors cheaper than the usual prices of 800 bucks for a 1.5 horse
 
I'll second eBay. I got mine for around $280 if I remember correctly. It is good up to 3 H.P and the brand is AC Tech. .


Hers a pic if my setup. Note that its mounted in an old ammo can to protect it as well as the control pad that is mounted to the left of the motor. I've had this setup for 2 years now without any problems.

ACTech drives are great and very inexpensive. I got mine for ~$270 new. Look in your yellow pages for "power transmission" and you can probably find a dealer locally. Or check the ACTech website. I think they have a dealer listing.

Try Automation Direct, I believe at www.automationdirect.com. From them you can get a drive and motor for less than $800. I buy them a lot for the company I work for; 24/7 runs in harsh environment. They hold up as well as AB at 1/5th the price.
 
I know that there are specific motors made for use with VFD's

However, i don't know anyone that uses them.

Normal 3 ph 220 VAC seems to do it.

As others have mentioned, they can be cheap
 
and the award goes to...................... efleming for the factorymation link, that is the most affordable motor and controller ive even thought of

it looks like i can get a 1 hp 1800 or 3600 rpm motor with a controller that accepts 115 volt 1 phase input that outputs 230 volt 3 phase for 300 bucks for the whole deal shipping would probably be 100 bucks i figure

can i just plug that in to my wall outlet in my garage and run the setup safely, or am i missing some fundamental concept?

by the way thanks for the link fleming

I used the FM-50-101-C ($120) for 115V single phase power operations and using a 3 phase 230V 1hp motor ($49) to convert my JET BD920 lathe to variable speed. I've also used the same configuration to convert my HF metal bandsaw to variable speed as well. Very inexpensive and works fantastic.

For something like a 2X72 grinder, I'd go to 230V input so that you can run a much stronger motor (2hp) as well as a NEMA 4X enclosure to handle the excessive dust.

The folks at FactoryMation are great to work with and are super fast shipping orders.

I do not know what you are trying to run with this setup but the FM-50 can work very well for many applications.

tryin to run a kmg or similar grinder, ive also got this crazy idea to run belts off of one motor to a grinder in front and a bandsaw in back just tryin to save money on motors, but these folks seem very affordable, might not be as much of an issue as i thought, id like to get rob frinks opinion on a setup like this, motors, dual machines on one motor and the 100-200 dollar controllers........rob?
 
If you are converting 110VAC 1-Phase to 230VAC 3-Phase please check the FLA of the motor you're using and verify wire and breaker size for the outlet you will be plugging into. Probably already OK, but a quick check could save lots of trouble later on.
 
Get a motor rated for operation with a VFD if you can. The output voltage of a VFD is a PWM waveform and will contain a lot of high frequency voltage spikes that greatly exceed the voltage of the 50/60 Hz waveform. This shortens the working life of the insulation in the motor. Motors built for use with a VFD use insulation with higher voltage rating. If you are doing this for a hobby, you can get away with it.
