Stromer moter will do walk assist only

Hi Folks!

I have a bit of experience with electric bikes
http://www.evalbum.com/5024

but i have an stromer moter, en i will this use for childers go kart.
now iam testing it, but with throttle it does only 6km/h, ive only connect the fase wires.

on my hs3540, only connect the fase wires then work the moter...

any suggestions ?

Stromer is hard to test on a stand... Hard to pedal hard enough to trigger the torque sensor in the rear dropout.

Damn!

I've sometimes disconnected the brake cut off for the rear, then you can lightly hold the brake while pedaling to get enough resistance for it to trigger...

Also, it's been a while, but I think buried in the setup screen there are settings for how high the throttle will go also, but the system really isn't designed around throttle use...

Maybe i open the moterhub, and connect thefase wire... So al the other elektronic dismantel .?

Hard to open... You have to undo all the spokes and pull the two halves apart... Not like regular ones where the sides come off

What type (from which version of Stromer) is the motor?

Opening the motor is indeed quite a task, here is how I do it:

1) remove rim/spokes (separate them, one side is longer than the other side)
2) Use a "bearing puller" which you hook around the edge of one of the motor halves (see image below)(place the 'center bolt' of the bearing puller on the axle and tighten the bolt to pull the cover off the motor)(you can use a rubber hammer or hammer+piece of wood to tape the motor halve whilst under tension to get it to loosen up more easily)
Make sure the 'gap' that forms between the two motor halves is as equal as possible (the distance between the two halves should be approximately equal all the way around whilst pulling the halves apart).

Whilst you have the motor apart (if you plan on using a higher wattage than the rated 500w nominal) I would suggest glueing small spacers (I used matchsticks) in between the gaps which are in between the rotor magnets. this prevents the magnets from detaching when the motor gets too hot. I used 2 component glue for this.
