I found a Brushless Washer motor on Ebay, and am going to use this for the drivetrain.Brushed had too many problems at higher RPMs / prolonged usage.Stay tuned!
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...
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...
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....
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...
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...
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...
The most simple form of an electric motor is a brushed DC motor where two brushes are used for power transmission and commutation. The disadvantage is the fact that the brushes burn down and need to be replaced regularly.In a BLDC = brushless DC 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...
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....
