Re: [Emc-users] Three Phase Motor Hack

Hello Kirk, this motor looks like an ordinary asynchronous induction motor. It is constructed for slow drives with large angular momentum, for instance, a large fan propeller, slow running in order to make as little noise as possible. Supposedly it's been running on single phase AC, so there

[Emc-users] Three Phase Motor Hack

2011-11-11 Thread Kirk Wallace
A short story for the curious. I was hoping to hack a motor to get a short (pancake like) three phase motor. I used a motor from an old box fan, similar to this one: http://www.surpluscenter.com/item.asp?item=10-2121catname=electric My motor had a stator core with six poles so I cut the wires
