so now I am coming to buy one of these geared AC motor with VFD control can you guys recommend me one that turns 0 to 500RPM please by the way guys my internet time has dramatically decreased but I'm still around should be back on regularly soon!
Winch motor output is rather slow and high torque to begin with.
Beats me why you need it any slower.
If you must, run the rope a couple of times through a pulley block,makes much more sense.
If you want a AC motor/VFD matched pair and have a local rep for WEG motors and VFD's , they get their engineering dept to look it over and suggest a matched pair for you !
