brushless motor animations and simulations

[Ron van Sommeren]

Hi all,

Notice, in all cases but the case marked with a '*', that the magnetic
field rotates faster than the shaft/rotor.

A very very simplified inrunner animation on this page:

Two better inrunner animations, the controller uses sensors but that
makesno difference to the motor itself. You can step through the sequence
or maximise your window to get the speed down:

The cd-rom motor simulation was done with a free magnetic field
computation program:
