Bustapepper Posted September 21, 2019 Share Posted September 21, 2019 I am wondering if the 1hp motor is going to be ok? If anyone has done this? I just want a motor to run off my 110v power. with a vfd Setup is going to be a 2:1 speed increase, motor is 5inch pulley, driven shaft is a 2.5 inch pulley and attached is a 7inch drive wheel to drive the belt. I know in an ideal world a 2hp would be the way to go, I just got this motor for really cheap. Using the formula 1760rpm2 x0.264x 7 = 6523 surface feet per minute. Just curious is all. Thanks for the input Edit: motor is 1760rpm Quote Link to comment Share on other sites More sharing options...

JHCC Posted September 22, 2019 Share Posted September 22, 2019 I have a 1-1/2 hp motor on my 2x90. It works, but I have been known to bog it down on occasion. Also, are you using the VFD to step up from single phase to three-phase? If you're going to that expense, why not just get a beefier motor while you're at it?

Irondragon Forge ClayWorks Posted September 22, 2019 Share Posted September 22, 2019 Our KMG has a 1 1/2 hp and it runs without bogging down. However it is a step pulley system for the speeds. The Grizzly I have used bogged down bad with a 1hp motor. Quote Link to comment Share on other sites More sharing options...
JHCC Posted September 22, 2019 Share Posted September 22, 2019 Mine's direct drive and therefore unadjustable. However, even with its minor limitations, I'd rather have it than not. Quote Link to comment Share on other sites More sharing options...
Bustapepper Posted September 22, 2019 Author Share Posted September 22, 2019 I got the motor for really cheap. The motor or a 5 inch pulley down to a 2.5 with the drive wheel attached to the driven shaft. I will have a vfd powering it. The power supply is limited in the garage at 20 amps so unless I upgrade my electrial panel and run 220v out there I am limited. I can't afford to do that at this time. I currently use a 5 inch angle grinder. So even if the motor bogs I think I'm a little better off than nothing. Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted September 22, 2019 Share Posted September 22, 2019 you dont need 240v for a 1.5 Hp, 20a @ 120v is fine Quote Link to comment Share on other sites More sharing options...
Frosty Posted September 22, 2019 Share Posted September 22, 2019 If 120v on a 20a circuit weren't enough I could't use my bandsaw or power hammer, I can even have lights on and until I get it a panel and connected the shop is on a 100' 10ga extension cord. Bad I know. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...

Of course you are right, go for it and you can always up grade the motor. Our KMG 1.5hp runs fine with 120v and 20amp breaker. Quote Link to comment Share on other sites More sharing options...
