    Variable regen drag brake for tandem bike w CA3 & PhaseRunner

    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 switch of some kind into the eBrake plug on the CA3. Once this switch is enabled, the CA will put out a lower voltage...

    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...

    Bosch Active Line 3 mid-drive motor tear down

    A great tear down, and fantastic website by the way. Have you figured out where you can remove any material to lighten the product up?

    Compact Field Oriented Controller, ASI + Grin, limited run

    What is happening is the controller is measuring that when applying power, the phase wires are not shorted to something it shouldn't be. It is cutting power because it thinks that they are. 1. You have very dirty connectors that are bridging between the phases 2. You have a random short of your...

    The Cycle Satiator, universal charger for the enthusiasts

    Just to let everyone know, the 1.026 FW was released, and you can use your Satiator Software Suite to grab the latest file using File -> Check for new Firmware. You'll need an internet connection to do this. This update fixes the "False Charge Complete" bug at the beginning of charge cycles...

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

    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).

    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...

    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...

    AVIAN featherweight mid drive

    Great job with the Cyclodial drive! No eBrake input. Just looked up the hardware. Having almost zero familiarity with the product and programming specs... I'm just grasping, but someone surely can give you some experiential feedback. You could force a short on the PWM signal from whatever your...

    The Cycle Satiator, universal charger for the enthusiasts

    This is a result of a failed soft-start circuit, hence the spark. For any other users experiencing this issue, simply email into Grin tech support (info@ebikes.ca) and they can help you out. The chargers will continue working, but the message will be present until the battery is plugged in...

    Compact Field Oriented Controller, ASI + Grin, limited run

    You might have a unit that needs some extra little adjustments due to the particulars about that production batch. But first, I'd like you to perform the following tests: 1. Disconnect the controller from the battery source and the motor, let the caps discharge 2. Connect the V+ and Gnd...

    Definitive Tests on the Heating and Cooling of Hub Motors

    I would also consider looking into sealing design on dirtbike/motorcycle output gear shaft seals. Dirtbikes especially see a lot of debris/water and are typically oil filled on the other side of the transmission case. Car ICE crankshafts are comparatively tame in terms of contamination when...

    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...

    For those annoyed by the 6,7 blinking pattern; It has to do with the "ColdBatteryFoldback" temperature settings. By default they are set to be 0 and 0, this is apparently giving a warning, even though it is the recommended default. To fix this on the PhaseWarmup software you'll have to change...

    Hey Mr. Bill, You can set a "regen brake speed" which will cut the regen braking off when below this speed. -Robbie

    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.

    The Cycle Satiator, universal charger for the enthusiasts

    Everyone should update to the latest software as we found a bug that depends on the order in which you update the firmware, which can cause the unit to enter a constant taring state, as described by Crezzy2k1 and Bjornb. Crezzy2k1, Bjorn, We've been able to recreate this issue quite...

    Compact Field Oriented Controller, ASI + Grin, limited run

    Downside is that because it is a tuning parameter, and depending on the variables in your system, running it high might lead to undesirable performance! I find on my Grin motor that running it at defaults is just great, but on my eZee motor (1500rpm unloaded, 16 PP, 24000eRpm) I had to...

    Compact Field Oriented Controller, ASI + Grin, limited run

    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. 12uH is really low.. haha wow.

    Compact Field Oriented Controller, ASI + Grin, limited run

    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...

    Compact Field Oriented Controller, ASI + Grin, limited run

    Are you running sensored or sensorless? Double check your rated RPM is appropriate for your voltage, and that your Rs & Ls terms haven't changed for some reason. After that, it's time to start playing with the current regulator bandwidth. I found high RPM and low inductance motors would...
