    Cute100 internal phase resistance

    Wow, that's a good frying of the windings...hehehe! Have you any experience of the newer follow ups to the silent Tongxins? Isn't it Keyde that has friction gears instead of cogg wheels? Or is it only Tongxin that has a new and more reliable motor?

    Cute100 internal phase resistance

    Did you check the cause of death on your first failure? Gearbox, winding etc... Btw, do you find the Q100 silent? Or does it whine at higher loads?

    Cute100 internal phase resistance

    Hi, this is good and low values. What was the Volt & RPM spec of your Cutes? (For a quick comparison to my older models!)

    Cute100 internal phase resistance

    Hi. I'm trying to find some info on the internal phase resistance of Cute Q100. By this I mean the ohmic winding resistance between phases. It's very easy to measure. Just use any power supply with adjustable output current. Set the voltage to 1V and current limit to 1Amp. Then apply...

    Re inventing the wheel

    Nice new idea but how do you fit a hub motor....as for now, you don't!

    Safe to run 24v Tongxin motor on 36v?

    @ amigafan2003 I simply thought modern of shelf controllers could monitor motor currents and therefore I asked about folks experience. Now I know better...... @wurly I will certaintly share all details. I initially bought 3 Tongxin motors back in 2008 but never got around to finish my...

    Safe to run 24v Tongxin motor on 36v?

    Hehehe, my controller is not bought of shelf but a design of my own that is 110% correct in all readings. When I set the output to a certain level that is the true output without any overshoots or current spikes. It also ramps up output currents very gentle with no jerky forces at acceleration...

    Safe to run 24v Tongxin motor on 36v?

    Is the 650W limit of yuors measured at the batteries or motor, that's a big difference. My own controller limits both battery current to 12.8amps and motor current to 20amps. The output motor limitation is adjustable between 10-20amps by a pot while riding. E'g at hill climb or standstill start...

    Safe to run 24v Tongxin motor on 36v?

    Hi, I'm using a 24V Tongxin myself at 45V but I'm a little worried about output motor current. What current limit did you set for your motor? I don't mean battery limit, only motor current limit to prevent slip. I've been running 20 amps for a while with no problems but I'd like to increase...

    Making your own battery pack

    Very nice review. I enjoyed reading it. My own AA pack is divided into three 12V sections of paralleled cells. Each section is made from 4 blocks of 10 cells in series. When charging the AA pack each block in each section (a total of 12 blocks) is being charged independently by a special...

    Making your own battery pack

    I have made my own batttery pack from 120 pcs of NiMH AA cells at 2.2Ah each. Titanium AA 2200 mAh NiMH Rechargeable Battery (TPEH-TAA2200) The pack capacity is 36V 8.8Ah at max 12 amp continuesly discharge. The weight is 3.5kg including the homemade batt box and very special BMS. I...

    TongXin (a.k.a. Nano) motor project

    Hi Frederic. I ordered them directly from China by email exchange with Diana Lin. She was nice and sent me a spread sheet with their price list. You can reach her at xinyue_china-at-hotmail-dot-com Once I knew which motors I wanted I got an Proforma Invoice on my order from Diana. The...

    TongXin (a.k.a. Nano) motor project

    Here's one of my three Tongxin motors I ordered a couple of weeks ago. The controller is my own homebuilt design with "Smooth Ride Technology". As soon as I have mounted the motor into my 28" wheel I'll report my experience of this little beast. I hope to reach at least 20mph with some...

    TongXin (a.k.a. Nano) motor project

    Just to enlighten you all, this controller is not sensorless. It will require the Tongxin motor with Hall sensors. It is the eight wire motor with halls I'm referring to. I have named the current vs peddeling auto adjust feature to "Smooth Ride Technology" Simply meaning, the more you...
