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

Hello, does the tsdz frimware can be used for other motor such as XF motor ? 36v250w TS controller XF motor run smoothly with original firmware.u/v/w phase wires ,hall wires,throttle wires were connected,but without the LCD3 display and pas . I downloaded the KT-LCD3-v0.18.2.hex and TSDZ2-v0.18.2.he...

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

Hi, When I start to ride under PAS mode, the motor works intermittently, with a creaking sound. Yet when I speed the pedaling up, the abnomal sound disappear and it goes smoothly.Do I have to worry about parameters? PAS magnets:5 timeout:3125 ramp end :1500 or 18750(10rpm) ramp start:64000 pas thres...

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

Try to disable FOC and increase motor speed and current and then take the screen shoots and show to us. FOC was disable and the waveform was still asymmetrical.i tested other brands of controllers,there were all the same. maybe it is normal. what is the angle interpolation used for? #define DO_INTE...

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

@Xnyle has implemented the experimental function PWM off in the Java-tool. You can try this setting. But rotating the wheel by hand is not a normal use case, while riding or pushing your bike you won't recognize a resistance, as the control loop will keep the current at zero fast enough. I can reco...

[ Can you explain again, please, I don't understand what the problem is. the controller was powered off,rotating motor was easy. the controller was powered on, i felt resistance when i rotated motor by hand , so i think the motor should be rotated smoothly without resistance even thought the contro...

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

I pedaled a little hard when the controller was turned on , without throttle and PAS. the motor maybe working,are there some setting to avoid that? :D

Was the other controller a square wave or a sinosodial one?

regards
stancecoke
it was sinosodial controller.And there was a strange phenomenon the throttle was full but the motor kept standstill,just like the motor stopped at special position,the motor couldnot be started.

It's a mecanical problem, you can try to increase/decrease the tension of the spokes, but that might just shift the resonance range...

I'm using the BionX IGH3 with our firmware. It's completely quiet except small resonance vibrations in the range of 12-14 km/h.

hi,stancecoke
with my direct motor the small resonance vibrations in the range of 11-12km/h,could it be fixed?

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

Hi, i have some questions about the values ui16_pwm_cycles_counter and ui16_pwm_cycles_counter6 .when motor is near zero speed, the values range are 1----pwm_cycles_counter_max(3125). when motor is running, the ui16_pwm_cycles_counter range is 1-6???? the ui16_pwm_cycles_counter6 is just 1,no change??

TIM3 counter period = (1 / (16000000 / 16384)) * (65535 + 1) = 67 S not 1 ms??

Hi ,stancecoke
Phase Asv =(phase a - voff + amplitude)/2*1.155-20
do you konw how to derive the formula,why it should be + amplitude)/2 and -20 ?

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

A question, how is the trottle response compeared to the standard fw? I think it is a bit slow on the kt fw. Almosty all “factory” firmware (including KT original fw) uses “speed (rpm) control”, and not “torque (current) control” for the throttle. That is, by shifting the knob on 2-3 mm, the motor ...

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

Hi casainho ,
Could you tell me the relationship between Phase A(SPWM) with Phase Asv(SVPWM)?and how to calculate them?

the numbers in ‘Phase Asv ’column are different with the firmware,are they be suitable for use?

yes, that's normal, as the motor starts in 6-Step mode and switches to 60° interpolation at 3erps.
ok,i see. How to understand the following formula? 256->360°?
ui8_interpolation_angle = (ui16_PWM_cycles_counter_6 << 8 ) / ui16_PWM_cycles_counter_total;

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

Don't give up. Try to find the right wire combination, otherwise the firmware can't work properly. (No firmware can work properly, if the wires aren't connected in the right order...) Thanks. I'v changed the hall order in the code three times,(such as 1-3-2-6-4-5,2-6-4-5-1-3,4-6-2-3-1-5) switch (ha...

Maybe my direct motor hall order is counterclockwise .when the order was clockwise on app,the motor run reverse even though exchange the phase wrie or “motor.c"--hall order.

I think (with angular measurement) -75deg equates to +285deg? I'm sure someone will correct me if I'm wrong.. :wink:

Hi,Xnyle
i want to aviod the motor startup noise,so i follow "Diagnosing motor startup problems using the app”step,
is my motor angle 105-180=-75??
and how to adapt the number -->Hall Angle 4,Hall Angle6.....Hall Angle5 with different motor?
