General discussion

we are working on renesas controller for motor control. can we have any tools to check the waveforms from renesas controller in VESC tool?

Hello everyone I have two VESC6 MKVI hardware with me, while configuring using Welcome and Wizards -> Setup FOC Motors out of two VESC module one is working and another one is not working. What can be the issue. configuration I followed is same 

I would like to make a vesc for powerfull motors, 100kw and more, such as the Axiom: 100kW motor controller. Can I take this schematics from the "vesc 75/300", and just change the input voltage from the battery to lets say 200amp/400v, for the nissan leaf 80kw bldc motor, and scale up each part that is not holding up. for example this mosfet or igbt, insulated gate bipolar transistor, can handle 1000v, 400a. https://www.aliexpress.com/item/32686416981.html. maybe it needs more cooling.

Hello everyone,

             I have TRAMPA - VESC 6MK VI and GL40 motor and 12.6V and 6A  provided using DC power supply.  My project requirement is to get feedback from motor i.e. direction of rotation and speed and based on the input I should drive motor in same direction.

Hello,

I use the VESC 75/300 for my future electrical go kart. I have SMPM 20 kW. I would like to measure and calculate psi angle (angle between emf and current). To do that I measure the angle between hall sensor and emf/current. My issue is when I measure the angle between my current and my sensor, my current is very polluted by a 5th harmonic. Is it normal to have one ? Is there anaything I can do to avoid it ?

Thank's in advance for your time.

Hi all,

I would love if someone could briefly explain the "Stator Saturation Compensation Mode"  setting in VESC tool V.6.00

Specifically if I choose "Lambda" as the compensation mode which is described in the help box as "This requires that one of the observers with Lambda Compensation is used"..

Does this mean the setting is dependent on another setting I have to tweak such as the 'Saturation Compensation Factor' or something else, or is the Lambda mode kind of automatic?

Thankyou,

Pete.

I am working on an engine driven, hybrid generator for a drone. The primary power source is my BLDC in regen braking mode. I have an 8HP engine driving a Flipsky 80100 7KW BLDC. I have a 12S2P LiON battery in parallel with the BLDC regen output and the load. The battery is intended to soak up voltage surges, act as an emergency power source in case the engine dies, and in general be a very large capacitor. I am intending on starting with the battery nearly at nearly 100% SOC, and have made a circuit to limit the max output voltage from the BLDC to about 48 volts.

Is it possible to programme a VESC to flatten out the discharge curve of a battery? For example when the battery is fresh there is plenty of power so you dont need full throttle, Perhaps the VESC could compensate for this, whereas as the battery voltage depletes more throttle is needed. 
Is there a way of adjusting the throttle calibration/ introducing a limit and then adjusting that as the percentage of charge drops?

Does anyone have any experience of doing this? 

Thanks

Hey all-

I purchased two of these in early 2021, and one has been sitting on my shelf since then. Was used once for testing, in the aluminum housing, never been opened or modified.

looking to get $400, or best offer (unsure how much these sell for).

send me a pm + thread reply because I probably won't see a thread reply :)
