VESC with large motor

Submitted by ppet36 on Sat, 2025-02-15 17:28

Hello everyone,

I'm stuck with configuring my VESC for a large BLDC motor. I have a VESC Tronic 250R and a C30 motor from Begode, originally used in their Nikola, Tesla, and EX EUC models. The motor weighs more than 10kg, including the tube and tire. It has 56 magnets and hall sensors. Unfortunately, I don’t know the KV, but I estimate it to be around 75-100. The whole setup is powered by a 24s10p LiPo battery.

Nothing works for MY1020 3kw 72v motor and flipsky75100

Hello everyone. For a project, I want to precisely control a MY1020D motor (3kW 72V) powered by a fixed 72V 42A power supply. An Arduino needs to control the Flipsky via UART.

But right from the motor configuration in VESC Tool 6.05, there are many strange things happening. When I run the FOC motor setup, it finds a "motor current max" of 150A. However, neither my power supply nor my motor is designed for that.

Then, when I start my motor using the small "play" buttons next to I, RPM, D, etc., either:

vesc throttle response

Hi,

hope someone can help.

im setting up a vesc 60100hp on a bosch gen4 mid motor (No sensors. driver board removed)

The motor detection works fine , as does the throttle detection (chinese ebike hall sensor type)

the throttle is mapping at 2.5v max input. Using the 3.3v not 5v

however the motor starts at approx 15% and is full speed at 20% .

its practically an on off switch, although there is a ramp if your really careful rolling on.

this is the second vesc ive tried and both reacted the same.

PPM+UART. RC and esp32

Hey, everybody. I have a problem. I've RC and a receiver that works via ppm. The communication channel works fine, the motor spins, there is also esp32 which is connected via uart. How to make them work together? I need to control the throttle with the rc and esp32. in ppm+uart mode to control the throttle only works with the rc remote.

Trying to run a refrigerant compressor's BLDC with VESC

Submitted by logansheaf on Wed, 2025-01-29 02:01

I'm having trouble getting this going. 

I'm using a Vesc 6 with a 60v bench power supply (1200 watts max). 

 I can get resistance value with a multimeter but thats about it. 

Click on individual specs: https://www.siamcompressor.com/technic/#!/spec_mobile/36093/3/0

That will show all available motor specs. 

Can someone guide me in the right direction?

 

75100 recognized as 75300 and nothing works

Submitted by anaka on Mon, 2025-01-20 19:59

hi people i'm new on vesc and on this forum

i just got my 75100 pro v2 and installed

i also made the update to the latest firmware

the hardware is recognized as 75300 instead of 75100 so i have several stuff not working at all when i go to setup motor, throttle and so on

 

how can i fix this issue? 

What constitutes a continuous vs burst current?

Submitted by Alistair Goodman on Tue, 2025-01-07 16:08

Hi all, 

Quick question about currents.

I'm wondering what constitutes a 'burst current', i.e. how long would the burst need to last before I could expect the VESC to blow. 

In my application im using a VESC 6 75 and will usually be below the 80A recommended max continuous current, but may go up to the 120A burst limit for approximately 0.5s (Assume a sine wave current lasting about 1s with a peak of 120A).
