  • Motor as Encoder

  • Inspired by the attempts of other people around the Interwebs, I use a motor as a rotary encoder, but with a different approach.

  • BLDC hardware emulation

  • Something that bothers me for quite a while now: why is there no small / cheap hardware emulator for BLDC motors? I've seen contraptions where two motors are coupled and one is actively driven whereas the other just has a resistive load hooked up to...
  • BLDC testing rig

  • Long time no see! For two months melancholy was my companion, but it seems that season ended x)And I want to introduce BLDC testing rig, as stated somewhere above. Here it is: Designed to measure thrust generated by a propeller, for that purpose...
  • BLDC alpha-test!

  • I fixed that board from previous update. I wasn't carefull enough and forgot to connect some nodes together, and though MOSFET drivers still die when I power everything with voltages greater than 10V (dV/dT problem?), under that everything works fine....
  • BLDC controller trials

  • I had an intention to use amazing PowerPak housings for transistors. And guess what? I managed to fail that twice by assigning things to a wrong pins. Firstly, I messed with a gate and after milling second version I realized that drain and source were...
  • Driving HDD BLDC motor

  • A Hard disk drive motor has more coils than this simple triphased motor. Practically I have found 24 stable positions. The basis sequence of 6 positions is thus repeated 4 times. And 24 is a very convenient number for a clock !As we have 24 stable...
  • BLDC controller bughunting

  • Time to time work with electronics is deeply confusing.You may have 3 identical FET drivers connected same way, but still - only specific one burns out. Again and again. I've changed resistance (Rgate), and it seems that situation with heating improved...
  • Upgrading to a BLDC motor

  • I recently decided to upgrade the motor on my Rockwell mill.  The existing motor is a 3/4hp induction motor and it's OK... but has a bent shaft and mismatched step pulley. I'm upgrading the motor to use a 4kW brushless hobby motor, which is...
  • BLDC motor and controller theory

  • What is a motor controller? Why do we need it? What circuit topologies are commonly used? These are all good questions and I will try to provide a little bit of background from my limited knowledge on the subject.DC Motors:Let us start with the Motor....
