    New 100A FOC controller project

    Hy guys, As mentioned in my post New Custom Motor Project for Solar Car Here i'l describe the FOC controller. It's design begun a year ago, when i started looking into making an single board all smd FOC esc and also started developing the FOC code for STM32 uC-s. A verry big inspiration for code...

    Motor Winding Calculations & Cooling Design

    Hello guys, I have been searching the internet for a log while, about formulas and books how to calculate the windings of a 3 phase motor, i.e. nr of turns, wire thickness etc. I found some good theory books, some good sites explaining stuff, but haven't found an actual practical example with...

    FOC questions

    hello to all, I have studied FOC motor control for a good while now, i understanded most of it. If i remember well you have done you own FOC code, so i have some questions about FOC algorithms to clear things out. So far i understand and made (code) the following: clark transform from Ia, Ib, Ic...

    Magnet coverage and hall sensors

    Hy there, as you might know my 20kw motor (see photos here https://endless-sphere.com/forums/viewtopic.php?f=30&t=113852), it has 40 magnets 10x5x40mm N45 and the space between them is about 5.25mm, and that gives a magnetic coverage of about 65% (a bit to low for my opinion). Now at low load...

    20Kw motor and 300A ESC (ultralight aircraft propulsion system)

    Hy guys, i will move here the discussion about my 20Kw motor and 300A esc. This is been a project for my past 6 years, it's been a huge learning curve. Before i started this project my experience with electronics was with power audio circuits, analog stuff, and nothing digital. I will start...
