Hi, I'm new to vesc and just encountered my first problem. The e-bike hubmotor is not running in FOC mode, it is just making weird noise. It is a mxus xf40-30h 1,5kW motor.
I made a video:
The FOC setup wizard detects the motor and turns it, everything looks fine and when I select sensorless the motor is turning.
I am evaluating VESC using a VESC Six EDU. The application is propulsion for a solar powered fixed-wing UAV, so efficiency is the primary metric on which I am evaluating VESC.
The motor is a Scorpion S-5028-220kv. When VESC performs parameter identification on the motor, it reports: R=12.5mOhm, L=18.59uH, Ld-Lq=5.62uH, lambda=3.651 mWb. On my scope it has very sinusoidal BEMF when spinning with a drill.
The motor is mounted on a thrust stand with a propeller, and I am comparing to a Castle Creations Phoenix Edge 120HV using the following methodology:
I was happily using a VESC MKIV for long time on my cargo-shuttle. Unfortunately recently I had a cascading failure that was leading to 4 dead ESCs. I was changing spokes on my rear wheel with the motor - while doing so I must have damaged the cable going into the motor and motor phases with 48V where shorted to the HAL sensors. This made my old trusty MKIV go bad. Unfortunately initially I did not know what the root cause was - and just thought the controller died of old age or some freak error.
It's been giving an error for a couple of months now. Looks like it's getting silently killed?
Hi guys. I'm new to this and I have a problem that I've been solving for 2 weeks and I can't solve it easily, I can't get more power in the water than 30A(e-foil) Can anyone help me set it up? Esc-VESC-CONTROLLER WITH 300A 75V, Battery-12s 48V, 35Ah, Std discharge current 100A, Motor 5680, 540kw, 48V. Receiver and transmitter FERO. Thanks in advance. Marin
One of my new vescs (MakerX D75) is spinning the wheels correctly in the motor detection, but when I test the motor direction, the vesc short-blips and the wheel(s) will move slightly, but not spin. My other vesc is working fine with the same setup.
I need confirmation that I am not confusing terms here. As far as I understand, following terms appear in the VESC project:

I've got a single 14s6p p42a with two vescs for an awd skateboard
In the motor/advanced section, would the "battery current regen" be 25A (half of 50A) and the "battery current max" be 50A (half of 100A)?
And is that "-25A" and "-50A" or are they positive values.
Are there limits to how many times a VESC can be reprogrammed or how long I need to wait between updating the flash memory?
I have 3 VESCs that I am using for scientific research. 1 of them is working perfectly. However 2 of them no longer retain programming changes.
The two that failed did that at the exact same time when I was making several changes to the programming over a few minutes. The third one is fine.
The two that failed had been reprogrammed around 20 times.
I have a VESC MKV. I am able to use it with the tool, however, when I try and use it for remote control it bricks up. The error code I am receiving is: [vesc/vesc_driver-13] process has died [pid 16843, exit code -6, path to empty log file]. Has anyone dealt with this issue before?
