ESCs based on the VESC

[jaykup]

A list of all the active ESCs based on the VESC®

This is a WIKI so feel free to edit links/info.

All specifications are per side. No current rating standard exists so take all current ratings below with a grain of salt

The VESC measures current by using high side/phase shunts or low side/battery shunts. These design choices affect reliability and voltages.

Typically, 3 phase shunts > 3 low side shunts > 2 phase shunts > 2 low side shunts.

Based on VESC 4.xx (using FW4.xx)

10s and 12s FOC / BLDC. First public release of the VESC. 60k eRPM limit. Two low side shunts. Known for a possibility of frying DRV8302 chips when using 12s FOC.

Single MCU twin power stage VESC Branch

After the V4 controllers were released, a lot of various projects were spawned trying to design a controller that could use 12s on FOC and not blow up. Jeffrey Friesen @Deodand and Charles Allix @Blasto worked with Enertion to design the FocBox Unity. It is a single MCU dual controller with 2 low side shunts that could reliably run FOC on 12s using the V6 DRV8301 and DRV8303 gate drivers. This controller was a huge improvement in terms of reliability and thermal performance when compared to the original V4 hardware… but it wasn’t perfect. The built in anti-spark system was known for failing and they would still blow up from time to time.

After Enertion went out of business, they partnered with Lacroix and using the knowledge learned from the Unity’s successes and failures, went on to design a new controller called the Stormcore. It featured 3 low side shunts, a robust anti-spark system, and higher voltage options using the improved DRV8323RS and DRV8353RS gate drivers.

One unique feature of these designs is that they can run a parallel firmware often called “super single” mode and use both sides to drive one motor, doubling the amp output. Other dual ESCs that use dual MCUs are not capable of this.

The FocBox Tenka is a Unity with half the fets removed and fully potted.

The BKB Xenith is the same as the FocBox Unity, but made by BKB using the original Unity design files. Minor noted improvements were a more robust internal anti-spark switch and more heatsink mass.

VESC 6 based designs (using 60 series FW)

12s FOC/BLDC. 150k eRPM limit. Three phase shunts. DRV8301 based design. Generally more reliable than VESC 4 designs, and not known for DRV chip failures.

VESC 75/300 based or similar

16S-18S The design removed the DRV8301 chip which was limiting the VESC 6 to 60v. It has three phase shunts with independent gate drivers. Phase shunt designs provide very accurate current measuring, and all other things being equal, should improve reliability. It also provides a smoother acceleration from 0% to 100% speed.

TL;DR:

whats the best Vesc's?

I think the Spintend VESC is a good VESC, but its a little undertested. Lacroix also make good VESCs, the Stormcore 60D VESC is pretty well rated Focbox unity gets a mention although has moral issues surrounding it. TB VESCs aren’t tested in mass production yet, and after import tax I suspect they’ll be very expensive The single flipsky 6.6 VESC and the non plus DUAL are also okay Trampa ESC is overpriced

Solid resource and much appreciated dude

Very nice setup, and yeah gotta change to wiki mode

[jaykup]

Changed to wiki

[jaykup]

I guess the FocBox single should go in the Unity section as it was the foundation of the Unity and solved the 12s FOC issue without being a V4 or V6…

[Evwan]

true. added

[Trampa]

No, the Focbox single was basically a HW4 design and was running the 4.xx Firmware. It had nothing in common with the later twin designs.
I made some changes and split 75/300 and 100/250, since there is a big difference. 75/300 designs should use phase shunts, 100/250 based designs use 3 battery sided shunts. Depending on the motor, this can make a big difference. A200S for example uses 2 battery sided shunts as far as I can see.
These difference can play a big role, depending on the application and motor.

Also HD is not a HW 6 design. Uses battery sided shunts and different DRV chip. Wired differently and needs different FW.

[iNoLikeFlexyDecks]

@Trampa

HD is not a HW 6 design

Elaborate

[taz]

I believe he already did. Check immediately after your quote.

[tech.shit]

did you miss the FSESC 6.6 and 6.6+? as well as their mini/big variants?

[ShutterShock]

@Trampa

This ^^ not foundation of unity

[jaykup]

Can you help explain what difference the shunts on the battery or phase side make? I was under the impression that battery side shunts on the v4 lead to off timing measurements esp when running FOC and lead to the DRV chip failures/eRPM limits… but that appears to not be the case for later designs?

[Trampa]

https://vesc-project.com/node/403

Best is 3 phase shunts, followed by 3 battery sided shunts, followed by 2 phase shunts, followed by 2 battery sided shunts. 2 shunt designs do not react very linear on inputs. They tend to jump from 80% power level to 100%.
Quote BV: It will be linear to around 60% of full speed, then it will decrease for a bit up to around 80 % and then it will increase from 80% to 100%.

How good a ESC design is depends on many factors and powerstage/shunt layout is one big factor.

[Flasher]

Huh… no stormies

[frame.b022]

imo, i don’t think writing the S count in the V column is accurate. others have tried 8s or 13s (both liion) on a unity, and there are also user who uses lifepo4 cells which has a different S count compare to liion in similar voltage range.

Stating the absolute max voltage would be a more appropriate approach for this database.

just my 2c, great thread btw, already bookmarked it

[b264]

Voltage is always a better measure.

Real voltage too — actual kg·m²·s⁻³·A⁻¹ — not ebike-jive fake-voltages.

[frame.b022]

adding on to my point:

@frame.b022

Stating the absolute max voltage would be a more appropriate approach for this database

user should never attempt to build any battery pack, when fully charged, close to the absolute max voltage, unless the user fully understand the risk he/she is taking.
