Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

My other questions have mostly to do with which display to order If you want it simple and cheap, just use the display, that comes in bundle with the motor, no need to flash the display at all. https://endless-sphere.com/forums/viewtopic.php?f=30&t=98281 Tutorial: https://github.com/stancecoke/TSDZ...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

I would suggest to connect the torque-signal to X4, as the plug of the throttle may fit to the controller as it is...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

Could X4 be used in place of the throttle wire? Or is that a digital input? You can use x4 for the torque signal, if you want to use the throttle in parallel. We discussed that in the german forum just a few days ago, I added the information about the wiring to the german forum. https://www.pedelec...

I'd like to get rid of the fork judder at medium speeds and medium PAS levels. sorry, in this case, the firmware can't help, as it's a known problem of the capacitors used in the KT controllers. The combination of the motorcoil inductance and the capacitance in the controller seems to lead to a res...

Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

OK, first: you have to set the phase current limit to a much higher value than the battery current limit. e.g. max battery current = 15 amps --> max phase current = 30 amps. I'll add that hint to the wiki. If this doesn't help, you have to test differerent values for the Motor specific angle. All ot...

Now its back to 1,7amps. ... The controller is S06S from bmsbattery.

This picture is taken when full throttle and tyre in the air. 11Amps What kind of motor do you use? For a normal hubmotor, 11 Amps with tyre in the air is still much too much :shock: It should be about 2 Amps maximum. Again: is the current sensor installed on your PCB? 15 Amps can only be reached a...

Be aware that you need a normal BT module for the BlueOSEC App. The BLE Module that comes with the Kunteng is not working with BlueOSEC, see the Wiki pages

Sorry. I mean ordering the TSDZ2 or buying a torque sensor and a KT controller for use with my existing hub motor. Depends on your usecase. If you don't plan to climb really steep mountains and the speed is your most important need, you better keep the hub motor. The middrive has only advantages in...

Re: Kunteng Controller and compatible torque sensor

36v --> DC/DC step down --> 12V --> red wire (supply)

gnd --> black wire (gnd)

PAS signal --> green wire (speed)

throttle signal --> white wire (torque)

If you want to use a throttle in parallel, you have to use pad X4.

When I start to ride under PAS mode, the motor works intermittently, with a creaking sound.
Ramp start bigger than timeout makes no sense.
Use a PAS with more magnets and /or increase timeout.
