But would not lowering the duty cycle also lower the motor voltage, so I would not be able to drive up steep hils? Or am I confusing myself?
Voltage != Current
The torque and power wouldnât be limited, just the top speed
It was simple for me to like?
Just curious - if your remote allows multiple profiles are these settings you can apply to different profiles? Iâd like to have a slow profile for younger kids and such when they ride but Iâm not sure the best way to accomplish this with the VESC Tool.
For speed limits - maybe just change the profile on your remote if youâre confronted by the police? Seems crazy to have such a strict speed limit - doubt they have anything like that for bicyclists.
Remote profiles only change power levels, not top speeds.
When I look at the real time data when benching my board and calculate the top speed from the erpm shown in the vesc tool, I will get the same speed when riding it? I have limited the speed via lowering the duty cycle as you suggested,
Maybe not exactly but close enough, sure.
I will test it, im considering buying a metr to have multiple profiles. But maybe you could answer another question I have. I have bypassed the BMS by removing the -P wire and adding it to the -B so I am only charging through the BMS, but will regenerative breaking still charge the battery correctly?
Yes
I love this forum. I totally forgot about the ERPM and braking issue and didnât even think about limiting the duty cycle. Iâve been thinking about limiting my builds to 35mph.
When I am hitting my max duty cycle the motors starts trembeling, anyone might know why?
What are your settings?
25% max
22% cut off start
10s3 Battery
60 A motor
-60 A motor
24 A battery per esc
-13.5 battery per esc
The problem ended up being using BLDC commutation mode, switching to FOC fixed it.
Please only use the profiles to limit speeds and power. You can pair you board to the phone, so that a third party wonât get wireless access without your phone. Profiles use a dynamic dutycycle current limit, according to speed setting. They will ramp down power/ torque output before hittin the defined top speed.
Those only work in certain circumstances though, no?
On an ESC without wireless for example, you canât use them.
Assumptions are bad, especially assuming all batteries can output 99A per motor safely.
he did do a good meme tho, was ontopic
of course they can! just for that short period before fire everything is fine.
Are you assuming all esk8 are 2wd
Touché; fixed
