3KW 3-Phase Getting Assembled

  My Thunderstick PCB’s arrived some time ago, but it has been very hectic at work so I simply had no time to work on it. I also have a new 1kw motor that will be nice to test. The pictures above is the board with DRV8301 mounted. I have to start with this because…

Modular Control System

This drawing is an overview of the Hat’s in progress. A few is only on the planning stage, but most electronics is on prototype level and SW is coming on. Raspberry PI is the obvious core if I need heavier processing. Due to the nature of it’s SPI I can only connect one of these…

3KW Thunder Stick

This is my 3KW 3-Phase Motor Driver Rev 1.3. Revision 1.0 and 1.1 had air wiring, 3 current sensors and output at right. Rev 1.2 lacked RS485 while Revision 1.3 have CAN and RS485 + 2 temp sensors between MOSFET’s + I solder on cobber wires directly on PCB for 60V and GND to sustain…

BasicPI Firmware Stack

This illustrates the BasicPI Firmware Stack in progress. What I always do in embedded applications is to make a “standard” main.cpp as follows: void AppInit() {    // wire hardware } int main() {    AppInit();    // start OS } A team I worked in years ago agreed on this standard so we should…

3KW 3-Phase Outrunner

This pic is of a 6368-190KV while I just received a 6368-280KV – a 3KW Outrunner BLDC w/Hall Sensors that costed me 60.- USD all in all. This will be my 3-phase test motor on the 3KW Motor controllers thought while my controller is max 60V @ 50A these motors have a spec 36V @…

3-Phase 50A Modifications

I want to attempt a few changes on this 3-phase controller. Remove the 3rd current sensor marked in red at top. Remove the output holes at right and take the output directly from between the MOSFET’s. Add at least 1 temperature sensor. I can use more space between MOSFET channels and maybe squeeze in the…

60V 50A 3-Phase Driver

This is a specialized 3-phase driver that uses DRV8301. It is more narrow than the 4 channel design and not so complicated to build. I did this design before I did the larger 4 channel design so it is several things on this design I improved on the 4 channel design. Temperature sensors are still…
