Hello
I want to convert my lathe from 1/4hp single phase 120v to variable speed 3phase and I have a 1/4hp 208/230/460v 3Phase motor. From my research I have read that I do not need an inverter duty motor as I will run 230v into a motor rated to handle 460v (should be OK with spikes). My thinking is I will use a 115v single phase in / 230v three phase out - 1hp VSD as I may later upgrade to a 1/2hp motor and I feel I will get more life expectancy by over sizing and adding airflow via a small fan. I have read about v/hz control and sensorless vector control. It seems to me either would be fine. Although I think I would have more torque at lower RPM's with the sensorless vector. Additionally I wonder if the sensorless vector versions would provide better effeciency and/or longevity? Also (since I have never put my hands on a VFD) Do I need additional parts? Is there a speed knob on all versions? If not, does the keypad allow for control? Are they reversible? In my application, are there any other features / settings / controls I should consider? If possible, I would appreciate suggestions on models or versions. Thanks! Darren |
