Serious FOCer . TO-247 version
Little FOCer . vertical TO-220 version.
Flat Little FOCer . Horizontal TO-220 FET version
Mother FOCer . 12 TO-220 FET version.
- 15V to 84V operation
- Expected power of approx 5kW with TO-247 FETs and good heat sinking
- Has primary features of VESC controllers (FOC, configurable current/temperature limits, throttle response, dual motor operation, ect.)
- Different versions for different FET packages
- TO-247 FET and 12 TO-220 FET versions for higher current capability
- Single-sided dual-layer PCB
- Small 45mm x 101.5mm board size
- Each switch node has it’s own bulk cap, pwr, gnd and phase cable holes. Reduces need for beefing up long traces for increased current handling capability
- Utilizes DRV8353RS to achieve higher operating voltage, superior fault detection, and small footprint. Also allows for tailored slew rate control to minimize ringing/spiking in the power stage
- Easy On/Off capability with switch of choice
- Wireless Bluetooth transceiver module can be easily added for wireless interface with VESC Android App. Allows for easy configurations of different speed/power profiles that can be selected at will.
- Design will be open sourced after verification
- Designed in KiCAD for flexibility and compatibility with the open source community

This is a higher performing controller in comparison to my Cheap FOCer controller that is about to go into beta testing. All lessons learned from the Cheap FOCer development has and will go into this new controller design. It will be a while before this is made a reality. new firmware will have be developed for the new DRV8353RS. Your patience will be appreciated on this one as I have other projects running parallel. In the mean time while we all wait for me to develop this, I am open to any suggestions that will help make this controller great for this community!
All this wouldn’t be possible without Benjamin Vedder’s hard work to build on. Please consider supporting him for his efforts through the link below.
