No, it's not common practice at least I've not seen it before. If I'm not mistaken, that's a clever method of varying the braking effect - by changing the magnetic coupling between the permanent magnets in the rotor and the stator windings.
It's novel because it allows for a fixed braking load; it also permits energy recapture on downhills without noticeable slowing the vehicle. This variable coupling is the core of the invention...

is the magnet sliding out of the hub like that common practice in this field of electric powered vehicles???

OOOOOOOOOH!

at 0:25 sounds like "scheise"

that is impressive.
though, i'm curious how much torque that motor can put out.

curious. i know this goes on a solar car, but could this application be used conventionally (for everyday use)? and how much power would need to be used to , well, "power" this motor?
also, on a side note, did anyone else notice the motor/wheel assembly vibrate at the beginning of the video? I assume that could be corrected?
this is a great concept, IMO, that should be put to practical use! :D

you can make a motor that runs off just magnets well i can i dont see how you all havent found it yet its so easy just the way you put the magnets every tells me it not possable because the magnets i use stoppes the force i am trying to make but it you put them in a way it dont event slow it down the motor has almost nothing pushing aganst to stop it if i had more power full magnets i could make a motor that can power the entire country and still have power to give

Hi Adkit2,
I have said you cannot produce power only with magnets without electricity,
By the way if you think you can, you'd better do it, and build a motor that way, running without electricity just with magnets,
this invention will make you richer than bill gates,
and you will also show that "law of the conservation of energy" is nonsense
