I think that maybe or motor is at 10 of 15 degrees and you should adjust instead MOTOR_ROTOR_OFFSET_ANGLE, because FOC will then be at 180 degrees, while adjusting MOTOR_ROTOR_ANGLE_STARTUP only, means your FOC will not be at 180 degrees... I want to delete from the firmware the MOTOR_ROTOR_ANGLE_S...

I just tested the motor torque with different startup angles. I used a pocket digital hook scale connected to the bicycle wheel to measure the torque and connected always on the same place on the wheel. At 0 degrees got a good torque like 20kg. At 10 degrees got like 21kg and at 20 (30 degrees) I g...

So about the controller running hot, I don't know more, maybe that is because of that 1/3 more time being commuting the PWM signal... maybe someday I will revisit this or maybe some one will do. I must say I almost never touch my motor controllers to verify this. I've been using a 'worst case scena...

I guys do not have so much spare time :S sorry. I need a VM to compile your stuff, learn how to flash it etc. I will do, but dont expect it in less than 2 weeks-4weeks. Sorry :S No problem, I completely understand this. I have the enormous advantage of being retired so can find more time for hobbie...

As you can see, I did measured a dead time near1us on my controller and firmware is using 1us. I think that if your controller dead time must be a littl...

I have found the '174' setting is, for me , at the extreme upper end of the working range, in fact when set to 180 the motor malfunctions and will not run. For me the 'sweet spot' seems to be around 120-140, at this setting the motor operates really smoothly with good torque. I think 130 actually e...

This you can test right now, go to PWM.c file and change that 16 value: // break, dead time and lock configuration TIM1_BDTRConfig(TIM1_OSSISTATE_ENABLE, TIM1_LOCKLEVEL_OFF, // hardware nees a dead time of 1us 16, // DTG = 0; dead time in 62.5 ns steps; 1us/62.5ns = 16 TIM1_BREAK_DISABLE, TIM1_BREA...

this value of 174 (244 degrees; 170 would be 239 degrees) was found experimentaly // seems to be about 180 + 60 degrees; were I expected to be 180 degrees #define MOTOR_ROTOR_ANGLE_FOC (174 + MOTOR_ROTOR_OFFSET_ANGLE)[/code] Please adjust the "174" value to something between 110 and max of 255 (inc...

TBH I find it hard to accept that my hall/phase connections are not correct, any changes in these would mean it would not run with the stock fw which surely can't be right? So back to the issue, if your motor runs but the controller get's hot, maybe is just some small angle adjust... I didn't had c...

Thank you Geofft. Great that you tested all the combinations. Was there a combination that motor rotated backwards?? Good to know that the same colors on wires works and my motors also. If the controller is getting hot, you are getting also lower range, right?? I think one setting after much judder...

Just tried this, things don't seem quite right. Please try the following process. I wrote it to install firmware instructions and if they are ok to you, I will put online: Hall sensor connections With the motor phase wires disconnected (it is recommended to insulate with tape the phase wires) and t...

Hmmm, you don't need to worry about that. But it is binary coding of the signal, like 5 is 101, 3 is 010, etc. Where 1 is 5 volts and 0 0 volts.

Ah...ok, now I understand.

Geofft, I would like to confirm that I also put TSDZ2 motor running using the same hall sensor: 2, 6, 4, 5, 1, 3. I just use the original TSDZ2 hall sensor connector, I didn't changed the wires. Also the BMSBattery controllers seem to use the wires colors connection. I'm hoping to get a chance to d...

If the motor get's hot but still runs, I would say that phases can be ok and maybe hall sensors sequence are not correct, can be something like 60 degrees advanced. I hope that with passing on this process will make it running well for you. Geofft, here is the code with a scale factor on config.h (...

I'm happy to give this a try, but I'm not convinced that I will find a better hall/phase combination though, as generally (other than the last fw download), the motor has always run quietly and smoothly. One thing I have noticed with my installation however is that the controller is running noticeab...

Updated master branch with the new angle value of FOC. It works and phase voltage is placed 90 degrees ahead of rotor position 0 degrees. The motor has max torque possible at startup. However, the FOC is now at 180 + 60 degrees; were I expected to be 180 degrees. Would be great if you guys can try....

Ok, I will a coeficient to config.h. What is you controller reference??

Had a request for a video showing wattmeter error a while back, so here goes:- https://www.youtube.com/watch?v=ztBQEd5Ex7E It's a bit hard to judge but I reckon the average battery current is about 8.5A, subtract 0.15A idle current gives around 8.35A. Average wattmeter reading is about 235w Battery ...

Good to ear!! Very happy the PAS is also reacting fast. Next thing I would like to try is to setup on LCD power levels instead of current levels, as this helps manage the battery range. Also means that when battery starts to drop the voltage, we should keep anyway the same assist level. Also batter...

Just had a short road test, looks like both problems are now sorted... :D Reduced PAS_ABSOLUTE_MIN_CADENCE_PWM_CYCLE_TICKS (main.h) to 50000 and PAS now quits very quickly. I guess there must be some limiting factor to how low you can go with this setting? Changed ADC_THROTTLE_MAX_VALUE to 182 and I...

I'm not sure people are gonna like that delay, it's just a bit too long and could create dangerous situations. I'm sure you guys will come up with a solution. Have you tried to reduce PAS_ABSOLUTE_MIN_CADENCE_PWM_CYCLE_TICKS (main.h) and/or PWM_DUTY_CYCLE_RAMP_DOWN_INVERSE_STEP (config.h) already? ...

Tried the latest master branch earlier, a couple of points that need a mention:- 1) Throttle is still restricted to about 50% in 'Full throttle mode', works as expected in 'Throttle scaled by pas' mode. Can you please look at ADC_THROTTLE_MAX_VALUE, as see if that value on main.h correspond to your...

Tried the latest master branch earlier, a couple of points that need a mention:- 1) Throttle is still restricted to about 50% in 'Full throttle mode', works as expected in 'Throttle scaled by pas' mode. 2) PAS cutoff when you stop pedalling is a bit too slow, taking around 2 secs. When you're not re...

Just an thought....we've found from previous tests and issues that there seems to be an -0.06v offset between the actual battery cell voltage and that seen by the firmware. That's not much, but it's enough to play havoc with the battery monitor. Maybe an idea to put the 'correct' voltages in that t...

The issue is that torque sensor max voltage value is different from throttle value, and maybe different from throttles. The min value is now automatically calibrated but max can't be, anyway, if typically we scale the value, there should be no problem. I don't see that having to set something like ...
