BLDC controller bughunting
Log from linear actuations for everyone!
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...

BLDC rotator plan
Log from P2 - Pick and Place for 3D Printers
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 very Basics - BLDC control
Log from Smart BLDC controller for eBikes with BLE
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...

Upgrading to a BLDC motor
Log from Rockwell Milling Machine Rebuild
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 Replacement and Failure Analysis
Log from TrillSat
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...

Maching some new parts for the BLDC

BLDC motor and controller theory
Log from Gator Quad
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....

New ESC and BLDC motor
Log from Arcus-3D-M1 - Full Color Filament Printer
ESC and motor got here right on time yesterday morning. Hobbyking is awesome. Assembled everything last night and powered it up. Everything fit on pretty much the first try and no_smoke.exe appears to be functioning. My wiring inside the stepper carriage...

schematic for geared motor or BLDC controller
Log from NSCE-ngbrain
Making two modes for TCPUSB class controller. Using BLDC controller for big vehicle (manual control, RF or Jetson_USB)or using geared motors for little vehicle (RF or Jetson_USB)

BLDC Motor Problems and Repair
Log from Open esk8 Remote - v1
In 2018, I had two bitter crashes which hurt me plenty. As a result, my front left motor broke some time later. A spring shim got damaged that reduces axial slack inside of the motor. It split into pieces (two of which I haven’t even found, yet) and...

BLDC sensor-less control - how to ?
.Stack entry by Wassim
Edit : Thanks for all those who provided valuable references and comments, I realized that sensor-less is not a good idea for my application, as it is low speed and as sensors are becoming more available with reasonable integration effort.____________________________________________________________________Hi...

Feelings of a BLDC Speed & Position Control
Log from STM32 Blue pill IoT expansion boards
Experimentation setupThe PS4 Joystick is a good way to manipulate multiple variables simultaneously which is suitable for experimentation. The touch pad adds possibilities for position reference.The Raspberry pi here is not needed for the BLDC control...
