How do brushless motors work?

Hi,

I'm kinda interested in how brushless motors exactly work. Does somebody have a good pdf file or something about how brushless motors work? Where outrunners, inrunners, 2-pole, 4-pole etc. is explained?

Thanks,

Patrick

They are so simple in design and operation, you will be surprised I'm sure.
