Servo,
I just disagreed with the 33% power loss on and manification of the VFD needed. Everything I have read to date on modern VFD's for HP under 10 states that Power is not reduced. Both my VFD's, one is a 3hp and the other is 1/2 hp, have full rated power and work excellent... I have actully been told by a friend that rebuilds glass bottle machines, that I should not over rate the VFD's. Although in the settings you can adjust for the exact motor you have. I just feel that VFD's are the way to go because of the programming you are able to do. I was amazed at how easy it was to set up and operate. Anybody that messes around with CNC programing would be more than able to program one. |
