Hey people,
Have bought a 3-phase lathe but only have single phase power, started research into VFD's, But no idea what I need exactly or where to buy one, There is a few on ebay but electronics sure isnt cheap China's strong suit so abit wary.
Current lathe only has a 2HP motor but may upgrade the motor in future or want to use the VFD on future machines. Does the VFD need to be exactly matched to the motor? or can you use say a 4hp VFD on a 2HP motor with no problems?
Whats the largest HP VFD you can run on single phase 15amp power, Im guessing 3hp since thats about the largest single phase motor you can run?
So yea just wondering on tips on what to look for in a VFD and if anyone can recommend a good supplier?
Thanks
