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

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...

Torn between this
What do you mean with "this". The torque sensor? The Kunteng Controller firmware? Higher speeds with which motor?!

But what is a pad x4 ?

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.

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

This march I built a prototype with strain gauges on the crank and an HX711 module . The data transmission from the turning crank to the stationary bike frame is done by the SPI protocol of the HX711 via infrared LED RX/TX - pairs. It worked on the workbench, but I prioritize my Lishui opensource se...

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.

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

You mean there is no sense in using a throttle, just like electric motor cycles or cars does? It makes no sense to push current through the motor windings when the motor doesn't turn. The efficiency of a electric motor is simply exactly zero at zero rpm. https://evmc2.files.wordpress.com/2014/07/mo...

We can provide motor assistance as soon user makes a specified minimum amount of force on the pedals, even before they start rotating. Of course we can, but what is the sense?! The motor will produce only heat and no mechanical power in this case. I don't think that with this function the accelerat...
