Hub motor slow to start and cutting out

[Nixtoo]

I've bought a very cheap front hub motor (250w 36V). It takes about 4 revolutions of the pedals before the motor kicks in and it is intermitantly stopping. I have tried with and without the brake cut out (to rule this out). I've moved the PAS closer (it's currently 2-3mm from the ring. The ring has 8magnets. I've increased the PAS sensitivity setting (although this seemed to make little difference). It's a SW900 displace and a generic controller rated for 15A (it's set to 12A in the display).

Is there anything else I can try or is this just a cheap motor so patchy reliability?

Thanks

Try a 1mm gap or less.

Try a 1mm gap or less.

Thanks, that seems to keep it going, but there is still a delay in it starting.

Any issue is to do with the cheap control system and not the hub.

Any issue is likely to be with cheap control system rather then the hub.

Thanks, it was such a bargain I can live with it being a bit slow!
