Changing to a Variable frequency drive
I am considering purchasing and installing a VFD on my griz 0462.
http://www.grizzly.com/products/G0462 I know I will need a new 220v 3 phase motor. I will need a vfd and controller for the new motor. I will need to provide a mounting and pulley for the motor and spinde shaft. My goal is to reduce the low end speed, and eliminate the vibrations caused by the reeves drive. and spend as few $ as possible, I'm thinking around $400- $500 My questions are as follows: 1. Is there a kit with motor, vfq and controller out there? 2. Are VFQ's available with built in controlers and are they more expensive than buying seperately? 3. What rpms and HP would you recomend for the motor? 4. Does anyone who has done this with a lathe have any tips or suggestions for me? 5. Is this a wise way to go about achieving variable speed? 6. Any supplier suggestions? (I would like to do one stop shopping.) Thanks for you help Wayne K Columbia MD |

Changing to a Variable frequency drive
1. use a 2 HP motor, 1750 RPM
2. buy the motor surplus, get it locally. you will save a lot - you should be able to get an excellent condition motor for $35 or less 3. get a refurb VFD - I use a Delta on my metal lathe (no, not that delta, another company called Delta that makes VFDs) - it cost me $200 from a distributor - so doing it my way your total cost woudl be around $250 to $300. You might luck into a used VFD via e-bay or a distributor or a swap meet, I've done that before also. 4. don't buy a kit, you will pay extra for someone figureing this out for you 5. I did this with my metal lathe (though it already had a 3 ph motor), see above for tips 6. READ THE MANUAL that comes with the VFD and understand it 7. this is the best way to achieve variable speed 8. if you want to do one stop shopping, you will pay more. to buy just a VFD, I would go to bob moffatt at thompson industrial. You could also check with Bill Rubenstein who friequents this group. I have a small VFD, I believe it's 1/2 or 3/4 HP that I coudl sell you, but you probably want a 3.5 hp one to run your 2 hp motor.

Wayne:
If you are interested in buying a new 2 hp inverter (a good one) and emi filter, contact me off line. I don't sell surplus, though.
