General discussion

Hey everyone, yet another cry of help post to add to the archive. I have a small issue that I've been puzzling over for almost a year at this point and I figured I would make a post and pick some brains to see if I can finally get this solved.

I have an electric motorcycle setup with a QS273 electric hub and a Trampa 100/250. I have the controller configured with a single throttle that supports both regen and acceleration in the same unit (Spin-y).

can i use a switched-mode power supply instead of a battery for testing?

Power supply: 2kW Output 52V 40A       BLCD Motor: 5KW 14S 220KV  100A

i use the controller to regulate a belt drive with a 35Kg Flywheel.

I change the some parameters for Battery management:

Motor Current Max: 100A 

Motor Current Max Brake: -30A 

Current Max Regen: = 0A

Battery cutoff start: 40V  

Battery cutoff end: 35V

Battery Current Max: 40A

Is there a way to install 5.02 onto the Trampa VESC6 MK VI?

It comes supplied with 5.03, but 5.02 works much better with Duty Cycle drive control on robots.

The MK VI came out only recently, so of course 5.02 doesn't know about it.

thanks,

John

After not being able to find anything with Google I compiled a lookup table below of fault code numbers to fault codes. Shared here for comment, as Im pretty new to VESC, and possibly to help somebody in future if they want to find fault codes using the CSV file in excel or similar.

I have 3 VESCs that I want to give individual different rpm commands over CAN BUS. Will it be better to use a mpu or mcu for this? Is there a particular library that I can use? Maybe for stm

Also what will the can connections look like? I have read that ground and 5V should not be connected. What is the reason for this?

And how do you carry over the CAN connection since VESC just has one CANH CANL set, will a pcb shield have to be made?

What is the suggested frequency for sending commands? and what bus load should you remain under?

Hey guys i ordered Flipsky 75100 controller running firmware 6.0 i paired it with 56.4V battery 13S5P + M365 PRO motor.

I wanted more speed something around 43km/h but no even if it has 80A limit and more voltage still runs 35km/h like stock xiaomi from the shop whats the point ? i need better motor ?.

Thanks guys 

I am looking for examples of heavy applications and experience thereof, 2-300kg vehicle, 15-25kW output. A controller such as a VESC 100/250 seems to be capable of great things but I have a hard time finding heavy applications or am I missing something. Please advice or link if you know of any, thanks a bunch.

Where I live the roads are very routh and there are many hills. I have to drive slowly and when going down hills I have to squeeze the brakes like my life depends on it. I would very much like to be able to press a button and the VESC would break or accelerate for me to maintain the desired slow speed. Can someone point me in the direction of how to implement this?

Another thing, I did not find much information about magnetic breaks and battery regeneration. How to use it with VESC and the dos and don'ts.

Thanks in advance for any help.

I have an older electric skateboard. What worries trans/receiver kit and motor controller do you recommend for a dc brushed motor? My motor has two wires only.  New controllers have three.  I'm going to power the board with dealt lithium 20 volts. 

Two questions regarding field weakening and MTPA:

1: I understand Field Weakening and MTPA can make the motor run faster. Is there a benefit to using either of them if the BLDC is used primarily as a generator?

2: These options disappear when I connect my Turning ESK8 V2. Is there something missing from that Vesc or my motor settings that would disable this option?
