troubleshoot my setup

[atom1025]

Set pole count to 80 and speed seems to read correctly now but as soon as I hit 28mph it wigs out.

Searching for this info is a pain. Be nice if someone started a sticky.

Also I notice a pulsating throttle when accelerating. Am I correct to assume this is from the current limiting? Its set at 30 amps.

Another notice is the infineon is super hot after a 30min bashing. My crystalite 72v35a would be barely warm after a similiar bashing.

I think the speedo problem is an incompatibility between using a CA-DP and a geared motor. Since the motor can freewheel the magnets stop moving. I think you have to have the external sensor type reading a magnet on the wheel.

Don't know about your other issues though.

Motor spinning too fast for the controller to keep up? Seems like there were some other threads about this problem with gearmotors.

Ok that makes total sense. I was wondering why the speedometer stopped reading when I kill throttle.

This is my first go round with hub motors and also my first experience with Cycle Analyst. Kinda bummed I have to put my cateye bike computer on as I was enjoying the uncluttered bars.

The MAC 10 on 15s Lipo is better then I expected! Same speed as my other bike but the torque is amazing! Really gotta hold on and it pulls wheelies! I'm guessing she tops out at around 30-32 but will confirm on the cateye.

Hope to have pics soon.

Was able to take her for another spin today and paid close attention to the watts. There's a big difference compared to my other bike. My other bikes part list can be seen in my sig. So first off the mac 10 yanks some watts when accelerating. Seen 2k a few times. My chain drive only hit 1300w when accelerating. However once at cruise the mac really shined at 25mph only sipping 700 watts or so. The chain drive ate 1000 minimum when at cruise.

So from 25 to 30 it seems to take forever to get there and eats the watts all the way there. In fact I never got to top speed in the track I was riding on as it was to short. It hit 31 and was still climbing before I had to brake. Prolly the current limiting.

So I have concluded the 12 fet 4110 infinion is not happy running this power. Its 130f at least on the case after a twenty minute slow then go around the oval track.

I think it would be wise to upgrade instead of limit as the motor seems happy.

I dunno I'm loving the bike but I am still not settled in yet. Open to suggestions, opinions, cursings whatever. I know no pics yet but my smart phone is stupid need to steal the wifes iphone and see if that works.
