Re: Variable regen drag brake for tandem bike w CA3 & PhaseRunner

I can’t figure out how to do this with the CA3 + PhaseRunner, or at least without losing my manual throttle. Any ideas anyone? The CA3 has variable regen enabled on it by default, you just need to tell it to enable the feature with the ebrake connection The easiest solution is to hook up an eBrake ...

Re: Cycle Analyst CA3 + TDCM torque sensor issues

The settings on the CA are pretty strange with 650Nm/V, thats way way higher than it should be. Usually TDCM sensors will saturate at like 3.5V (or so) when an adult is standing up in the pedals, especially with smaller chainrings. Out of curiousity, what is the mechanical configuration of the pedal...

What kind of top speed do you see motor power only on a flat?
I run about 5A of fieldweakening current through my PR, and a speed limit of 40km/h on my CA3 with 30A/36V battery, most of the time I'm averaging around 30km/h here in Vancouver commuting.

I'd guess around 36-37km/h (22-23mph).

Re: Bafang G310 geared hub - 11:1 reduction ratio!!!

I've been testing one of these for a few months now. The low level of noise that comes from the motor (when loaded - it can be a bit noisy running unloaded) is impressive. On my aluminum framed commuter bike paired with a phaserunner this motor is effectively silent. Any sinewave controller should p...

Re: CA3 - Phaserunner Speedo EMI Noise

The speed reading is a bit odd, as you added a connector to the Speed sensor, could you try adding a 1000pF ceramic capacitor to the connector and see if it filters out the noise? The Phaserunner has a precision (i.e. 1%) 1.00mOhm (milliohm) shunt in it, so you should set the CA3 shunt to 1.000 mOhm...

I would also consider looking into sealing design on dirtbike/motorcycle output gear shaft seals.

Re: Luna ga 14 ah shark pack

Do you know how much current you're drawing when the LVC is hit? Don't forget about IR losses in the pack contributing to the BMS interpreting the cells as being flat. Grab your multimeter, measure the OCV of the pack after a minute or two. You may find it's around 40V or so, which if you discharged...

For those annoyed by the 6,7 blinking pattern; It has to do with the "ColdBatteryFoldback" temperature settings.

Hey Mr. Bill,

You can set a "regen brake speed" which will cut the regen braking off when below this speed.

Definitely get the software. The firmware is not any different, but the software has a bug. Once you get the latest SW, you won't need to update the FW immediately as it is no different.

No - as far as I recall the higher the bandwidth, the faster the system will respond, I recall setting my geared eZee motor to a bandwidth of 3000 to get it running well.

Re: Compact Field Oriented Controller, ASI + Grin, limited r

It's probable that your eRPM is a bit high for smooth operation without some fine tuning. 9000 RPM @ your voltage * 7 pole pairs - 63000 eRPM is a bit higher than the conservative limit of 36000 eRPM. I also have notes that the recommended inductance limit (low side) is 50uH - and that users might e...
