Who knows their shit on electric motors?

Recommended Posts

@UTERUS yep very true startup load will be heaps more. I've got a motor at work that pulls 400plus amps on startup once running draws around 100.

The same size or even a 3 kw single phase motor is no good on a screw type hoist, ask me iv tried it even with gearing down the drive pulleys it stalled the 3kw 4 pole motor could  only lift a mazda6 on the hoist about 600mm off the ground, single phase just dont have the same torque a 3 phase motor has, @Kimjon im gonna guess that motor you have is star wound only for 400v (looks real similar to the one i had), if it could be hooked up for delta windings it could run on a single phase in three phase out 230v vsd but would lose torque due to the lower line voltage. Flick me a message if you have questions about motors and power calcs (im an industrial sparky by day)

Yea I had to gear mine down so slow it's comical, and it barely lifts an RX7.

Chuck a Briggs lawnmower engine on it

You would have to run it through a model T gearbox

Here's my switch board.

Is it pretty simple to connect a 3 phase outlet from here? I won't be doing the work obviously...but just after a reality check on feasibility?
