Quote snipped from this site http://ift.tt/1yXFjYn
The motors are all 3-phase, and as I do not have 3-phase in my shop I run these on single phase and a capacitor for the third phase. This reduces the real output power, but the drive motor is rated 550w and the geared "stroke" motor is labeled 90w, and both are more than powerful enough. The motor has never stalled.
Am curious, the way this is casually discussed makes me think that for this chap its common practice to do this, and also that its quite easy.
Do many people use 3 phase motors like this ?
Gotta be some traps ?
ie Find a competent sparky to install capacitor.
Not sure why anybody would do this unless they had a 3 phase motor lying around spare and couldnt be bothered to buy/find/swap a single phase motor at the time.
