    New "TSDZ2 Torque Sensor Central Motor"

    Thanks, I am trying to enter again the torque menu but I can t :oops: . In odo I press info + power for 10 seconds , but it always go to setting mode ( which should be the same 3 seconds) :x am I doing something wrong?

    New "TSDZ2 Torque Sensor Central Motor"

    It is a fixed parameter on the console, IE similar to wheel size , cut off velocity. Don't think this change with any input from the pedal. I see some videos people measuring pedal torque , but to my understanding this is not possible at least with the stock firmware. What I may do is push the...

    New "TSDZ2 Torque Sensor Central Motor"

    Thanks for the manual, max speed is deactivated. I check TE ( Torque signal value display)and TE1 and both are 80, is this normal value? In the manual the value printed is 0

    New "TSDZ2 Torque Sensor Central Motor"

    Motor is 48v 4000rpm, v5lcd. I have try in a trainer but not assistant at all. Bought it second hand will less than 200km. I was going to try casainho firmware at some point so it may worth trying.

    New "TSDZ2 Torque Sensor Central Motor"

    I opened the controller side, there is continuity. The red,black couple of thing cables I guess there are the torque sensor, and the 5 together the halls. The torque sensor works will have a signal proportional to torque apply? From 0 to 5 voltage, similar to a throttle?

    New "TSDZ2 Torque Sensor Central Motor"

    Mine has 6 pins, I will prefer the torque sensor, IE throttle just for trouble shooting, but don't plan to use one by default. How can I check the torque sensor?

    New "TSDZ2 Torque Sensor Central Motor"

    It is OEM, I don't have a throttle for this motor. I have a throttle in other bike ( with typical 3 pin molex connection )but I don't know how to connect it to this motor

    New "TSDZ2 Torque Sensor Central Motor"

    Hi I have almost new motor, but the motor doesn't start spinning. Battery and display are ok. The walking mode pressing minus button on the display does work, but when pedaling the motor don't work. I have follow the guidance not to touch the pedals before switching on. Any other thing I may...

    Hub motor not turning

    I end up opening the motor. There was quite some water inside and oxidation !!! https://photos.google.com/share/AF1QipOHaqdLQLICG019-c5owociEv1XANrbDYJfdhJrwnctlC1xhf1XDNwiHe6sX5LiPw/photo/AF1QipM52gpqMEJCTqcc1dL-4uSJ9iS9qkZoRpZUDhfP?key=ZENieUhVSHpyRVdXT0diUkVMZkgyMC1seGRVZVRR Two of the hall...

    Hub motor not turning

    Update. The bike has pedal sensor, i put the bike upside down. I pedal, It try to start but cant. If i mover the wheel a little with my hand (opposite direction if movement as It is freewheel motor) at the same time i pedal It starts working properly! :shock: . I was testing again hall sensor...

    Hub motor not turning

    I go for a small ride, not issues. It is strange i also tend to think that new connector was the issue as was the difference from before, but continuity is ok. I do disconnect the harness to repair a small flat tire could be that a hall cable inside motor get faulty? The only apparent problem...

    Hub motor not turning

    I checked the hall sensor voltage, as in ebike.ca . So power on , I checked voltage between cables turning the wheel by hand antifreewheeling wise. Red to black voltage is 4v Black to blue varies from 0 to 4 Black to Green varies from 0 to 2v Black to yellow varies from 0 to 1.7v Is It normal...

    Hub motor not turning

    The new connector doesnt seems to be the issue, i checked continuity and It is ok. Here is a photo if voltage entering the controller. 26 volts. https://photos.app.goo.gl/MjSEinkTfVBRvpG86 I have checked 3 pases cables and hall sensors cables from outside controller to motor hub connector and...

    Hub motor not turning

    I explained my self better: The battery is attached to be bike by this mount: As you can see is a seat post mount which has a connector plug the battery. I buy a replacement battery , which came with and adittional bike battery mount to the seatpost so: 1) I take the new battery and plug...

    Hub motor not turning

    Hi, I have a bafang front motor with Hall sensors and a seatpost attached battery. I order a new battery and was working fine with the old seatpost mount. I change the battery attachment aswell, And now the motor is not turning. I am not sure the attachment to the battery is the issue because...

    bafang motor with 9 wires

    The most probably is that is a speed sensor. This motor was from a well known bike company selling some ebikes so to be "legal" it must have a speed sensor so it stops assistance when the speed limit is reach. I cannot check the signal cos I broke my multimeter in the process of setting wiring...

    bafang motor with 9 wires

    hi i try with lyen configuration switching yellow and blue in hall and phases and seems working fine. 8) regarding the speed sensor, i guess the signal is linear with wheel velocity? i am planing to use arduino for throttle so i could use this for knowing speed? or as an input for a cycle...

    bafang motor with 9 wires

    Hi I have been around for quite a long time and have learn a lot from ES. I am building a kit by myself with a bafang 250w QSWXB, brushless planetary front hub and a Lyen controller. The motor has his own connector with 3 big pins ( for the 3 phases) and 6 ( yes six) small pins for the halls ...
