    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Yeah, don't know why I said lower Kv, Arber is right about different speeds/gear ratios I think. Either way, should work fine for DIY. Nissan have definitely been flexible with how they rate the EM57, given your example and the fact that they advertised a 'power upgrade' in some Leaf models...

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    I bit the bullet on a Gen2 motor, it was going really cheap (by UK standards), so I have something bigger than my ebike to test with. The Gen2 looks to have a slightly lower Kv than Gen1, going by https://www.marklines.com/en/report/rep1899_201907 . I'd help you test my Gen2, but shipping...

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Sorry to resurrect an aging thread, but has anyone tried this with a newer motor from a 2014 Model Leaf? I can't find much information on the differences between motor versions in terms of saturation currents/cooling/etc. I think Arlo used the 2011 motor based on what's shown in his YT vids...

    VESC and BBS motors

    I use a 4.12 VESC with a GSM (BBS01 clone), and I have absolutely no problems. I get smooth, immediate, solid power from a standstill. So I strongly doubt that the VESC can't be made to work for you. Have you gone through any videos about calibrating the VESC? I'd recommend doing that first...

    VESC Open Source - Android App Features?!?!

    Yeah, it was configured as slave. I played around with the AT+... settings, and eventually got it working. I set it to remote command mode, and made it discoverable and unsecured, and set the baud rate to 19200. I can monitor data, and read some config settings, but I use buttons and a resistor...

    VESC Open Source - Android App Features?!?!

    So I've got a VESC from Enertion (the most recent one), with all the parameters set up and working. It runs FOC on a bike hub motor, and works brilliantly. however, I've just bought a HM-10 BLE module to connect my phone, so I can monitor power consumption etc, and I can't get it to work. I've...

    DIY Stealthy Longboard Build Log (Integrated batteries)

    Great looking build mate! How's the motor position for ground clearance? Any trouble with bumps/kerbs/etc?

    Controller Stutter Issue - Help Needed!

    Those components are not blown up. They are a few low voltage power smoothing capacitors, and a few potential dividers to set over-current and startup torque for the JY01 control chip. However, that bike has just been stolen (combination locked through frame to massive lamppost - someone must...

    Controller Stutter Issue - Help Needed!

    Unfortunately, I don't have any other large capacitors that are rated for that voltage. I shall try that soon, when I get one, but there's already 300uF on the supply, which is a Turnigy Multistar Pack, so I'm not sure if that will help, especially if current limiting is disabled. I have...

    Shorted current sense pin to ground, No change.

    Controller Stutter Issue - Help Needed!

    The thing is, If I pedal up to speed, and then slowly increase the throttle to that speed, and stop pedalling, then it pushes me along at 20mph. At that speed, it's using about 7-8A at 30V, so it doesn't seem to be a current issue. (It stutters just as easily at 5mph, drawing 2A) It seems to...

    Controller Stutter Issue - Help Needed!

    What's strange is I tried powering it from an RC controller, and it works OK (at a much lower power level). It pushes me along at 5mph, and there's no stuttering or stalling at all. So I don't think it's the pole count/commutation frequency causing issues. It occurs equally for all throttle...

    Controller Stutter Issue - Help Needed!

    The negative battery connection is disconnected for safety while taking the photo. The capacitor is connected to the throttle input, so the throttle can ramp slowly, which works. Yes, the hall sensors failed, so I removed them. I agree that the synchronisation seems to be failing, but only...

    Controller Stutter Issue - Help Needed!

    Hey guys, so I've just bought this sensorless controller: http://www.ebay.co.uk/itm/191549381815 And it runs fine no-load. Lovely. When it has to push me on my bike however, it stutters under acceleration. If I pedal up to speed first, then increase throttle to match, and stop pedaling, then...
