AutoQuad ESC32 V3 - The Next Level ESC

[kinderkram]

Here we go ... finally!



Took a bit longer than expected but it was worth the wait.
With its features list like max. 10s lipos, max. 50A, Active Freewheeling, improved error handling or the unique speaker function, the ESC32 V3 sets a new milestone for electronic motor speed controllers for high-end multicopters and heavy lifters.

Bill Nesbitt teamed up with Felix Niessen from Flyduino (KISS ESC, UltraESC) to create this feature rich speed controller that delivers high performance and an absolute max. of 1500W with proper cooling.




Feature Highlights:

* Up to 10S and 1500 watts of power with good cooling has been acheived in bench tests.
* A highly efficient design using very fast gate drivers and FETs, yields a significant increase in efficiency and reduces the need for cooling at low to medium power levels
* Active freewheeling increases the response, stability and efficiency of your craft by actively braking the rotor during deceleration and converting the rotors kinetic energy to electricity.
* Real time current limiting eliminates the need for current limiter calibration and provides a user settable safeguard against overload.
* Improved starting procedure makes it plug and play with most motors. Start voltages and currents can be tweaked to improve starting further.
* A new drive method secures ultra fast speed transitions without loosing sync, both during acceleration under power and during deceleration under active freewheeling.
Improved failsafe support on AutoQuad with CAN; if a motor is disarmed or stopped in flight, the controller will try to rearm and restart the motor.
* Live telemetry is available over CAN in AutoQuad Systems – Displays for instance Power, RPM and Temperature in the ground control.
* Improved Buck converter supply circuit for the logic means that its safe to supply the logic side from the main battery.
* Direct USB support makes it easy to connect, setup, test and diagnose the ESC32 V3 with the new ESC32 Configuration Utility (ECU) included with each ESC32 V3

Specifications

* PCB size: 34 x 25.6mm
* PCB weight : 5.7 grams
* Interfaces: USB, Serial, PWM, CAN
* Input voltage range 6 to 42 volts (2-10S lipo)
* Nominal max power 750 Watts continous, 1000W peak
* Absolute max power 1500 watts
* Nominal max current 40A
* Absolute max current 50A

Features

* Active freewheeling
* Live telemetry over CAN, USB or Serial
* Real time current limiter
* User configurable current limit
* Control via CAN, PWM, USB or Serial
* Closed loop RPM mode
* Servo mode (experimental)
* Closed loop thrust mode (experimental)
* 8 to 64 KHZ switching rates
* Improved error handling with AutoQuad flight controllers using CAN control
* Improved logic side supply eliminates the need for external 5V supply
* Speaker function

Nice

Great ESC, but so expensive price. Not for all.
Thank you for your work.

Well, the V3 rather targets bigger camera copters where you usually start with 6s.
The lower voltages are well covered by KISS and UltraESC.

Next version of UltraESCs will come with CAN support, so it`ll fill the gap the discontinued ESC32v2 has left, feature wise and price wise.

Is there an ETA for those CAN ultras?

UltraV2 is still in development so I dont think its gonna be available this side of christmas...

Received my V3's yesterday and tested them on the bench today!

The size compared to the V2 is identical but they are quite a bit thinner mainly the FETs are flatter and on one side of the pcb. Which i really like because you can cool them with just one instead of 2 heatsinks.
Going further with the pcb, the lager motor pads are a welcome improvement as well as the improved buck converter which makes it possible to power the logic from the main power(even less wires yeahh!).

So i hooked up the V3 with a T-motor u3 with a 12x4 prop.

I started the ECU, connected and ran a rpm/voltage calibration. The V3 ran really smooth through the process, and with max current at 23amp's it ran 43ºc.
I also did thrust calculations for quatos, and ran in some problems with the V3 or the ECU not responding after manual rpm changes mentioned here .
Eventually i got all the measurement, and was surprised to have over 100grams more thrust at the max current over the V2. (Could that be an efficiency thing on the v3?)
Also the breaking on the motors is really fast, i got scared for a moment going from 9500rpm to zero almost instant i thought my motor had burned and was jamming. But no, it was just the ESC32V3 braking . I can imagine changing rpm that quick can give a real boost in stability!
Ill be installing the v3's on my hexa real soon and report back.

Cheers,

Ray

Thanks for your feedback, Ray!
And so quick.

Looking forward to your experiences...

looks promising! Thanks for this update.

Are there any features already implemented or to come to support FC-redundancy?
