This looks like the version you have. he got the number of balls wrong - one too many in the inner race and one short in the outer:

My wheel is brand new.I swapped the wheel for another and the problem still persist ,im getting fed up with it now.I will look up checking the controller with a multimeter and see if its the controller .Maybe its the gear the clutch sits in though it looked ok to me .

I have removed the potting,can you tell me the best way to test this now please .
You didn't need to remove the potting. You test through the wires.

Measure the resistance between each phase wire and the battery positive, then repeat for the battery negative to get 6 measurements. each group of three should be the same as each other and in the range 7k to 24k or thereabouts.

The other thing you should test is the hall wire connector. it has white rubber stuff to hold it in, but sometimes they don't plug it in properly before they put the white stuff on.
