Hi guys, after designing, and redesigning the design we finally reached the point where we kinda have almost semi-final design which we will start testing soon on the boards
So let me introduce you to the new FatBoy family member HV ESC
FatBoy HV ESC
Hardware Features:
STM32 microprocessor
DirectFET mosfets
Independent Gate Drivers / Current Amplifiers
Hall / Rotary Encoder support
CAN/UART interface
Voltage 4S-18S (15V - 80V absolute maximums)
Current up to 100A - 150A
This ESC will be available in single/dual configuration and will be using our CNC machined aluminium cases for outside/inside enclosure mounting with high-efficiency heat dissipation which allows us to provide higher constant currents.
Software
At the moment it is still in development but several hints it will be based on FreeRTOS and motor control libraries which would allow more precise sensored / sensorless applications.
For the prototyping and first devices, I have adapted VESC firmware to run on my hardware design.
Current project status:
Today we have received parts and PCB, soldered power and MCU stage everything looks fine will continue tomorrow and after we make aluminium cases for it I will begin testing in the field in my projects afterwards we will begin beta tests with several people and later on if everything is successful will be available to purchase from our online store.
One if the biggest I guess âDRV-lessâ design, independent power supply from gate drivers and etc. Higher voltage support. Software wise I am using industrial level software components with algorithms used in enterprise applications so it should be much smoother and better control loops.
Yes, I will be using these as 18S ESC on my Mark 48 as âbooster controllersâ
Canât tell if this is a joke because you are an absolute madman. Been killing it in the innovate game. Excited to see you progress. Absolute great job man
I was nurturing this design since last October and just finally got moving on faster after I started working on Mark 48 project But because of my own lack of resources I transferred all prototyping work to my father who is assembling them now
With the way youâve come in here and done what you have so far, I have a strong feeling youâre going to be the next Vedder. Thanks for everything youâve brought to the table here so far! Iâll buy whatever you come out with!
Dual esc with heatsink⊠im in.... This is next level..... Once again, DIY is raising the bar... Boosted, evolve and others, no thanks.... Its just toys
Glad to se the ânext Vedderâ is actually on the forum, where everything happens.
I donât think it will see day light in 1-2 months for sure⊠Regarding the price I can tell it will be for sure more expensive than ESCapes as gate drivers and etc cost a bit more plus it will come with the caseâŠ
Also there are some discussion regarding making single unified connector based on XT90 design for motors and sensor wire
Yeah, it should peak at around 10kW, but idea the higher voltage less current you need to consume to produce the same power Thatâs it will be coming with fully fledged case so it could handle those currents without going into melting
For e.g. same 4kW would require only 50A @ 18S instead of 80A
