Brushless motors are becoming more and more popular in many different devices and hobby projects, from drones all the way to electric skateboards and bikes. Compared to DC motors they have a much better performance, but this comes at the cost of more...
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!
The prism scanner uses a BrushLess DC (BLDC) motor to spin the rotor. How stators are winded can be seen in this video from Nide Group. The BLDC external armature fusing machine is used for spot welding the wire and terminal of the BLDC rotor I consider...
It's about time I stopped reading about the announced-last-week Apple Vision Pro and continued creating my very own little tech innovation. I've now ported over the BLDC part of the schematic, as well as make the power sections all look consistent...
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...
I'm going to use an STM32 as my microprocessor, and have that driving an L6234 as my 3 phase motor driver.I'm going to build it on velo-board first, but I'll be using the same SMT components I would for the finished product.I can do current control,...
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...
I purchased an old, used Lite-On LDW-411S DVD+-RW drive (manufactured in 2003) that someone was selling on eBay and removed the BLDC motor to replace the one that I burned out a few weeks ago due to the chip lock-up/stall issue mentioned in my earlier...
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....
