AlexMod | Open loop BLDC motor position controller
Details from AlexMod | Open loop BLDC motor position controller
The onboard microcontroller ATtiny261A generates 3 Phase (3 channels PWM for U V and W phase) 32KHz PWM from Timer 1. This result in resultant vector A.K.A position of the rotor of the BLDC motor. By changing the Sine angle (Step through Sine LUT). We...

Testing bidirectional control
Log from Modified ESC for Bidirectional BLDC Control
Success! We managed to get bidirectional control with an off-the-shelf ESC!Unfortunately, the type of ESC had to be changed, as we encountered numerous issues flashing different firmware to a generic SimonK-type ESC. Instead we opted to go with a BLHeli_32...

Why does my stepper motor not Rotate after being connected to the drive?
Hacker page by Mark Liu
Here is a quick troubleshooting guide on how to solve the problem of a stepper motor or BLDC motor not spinning after being connected to a drive. First, we recommend that you perform the following troubleshooting steps: 1. Check all wiring carefully....

How Brushless DC Motor Works?
Hacker page by kellygreene0805
Industrial applications all over the world frequently use brushless DC motors. First, there are DC (Direct Current) motors and AC (Alternating Current) motors. As the name implies, DC motors that employ no brushes are called brushless. While it is clear...

Week 1: Research and more Research
Log from My Journey of Building a Performance Quadruped
I have a huge project ahead of me, and in order to be successful i have to be as prepared as possible. I began looking into a whole bunch of open sourced quadrupeds. I mostly only looked at mammal like robots with two sets of parallel limbs. Not the...

BoostWheel
Details from BoostWheel
I am currently in the forumlating stages. The current build plan is as follows:1) Find a suitable motor for prototyping: currently considering the MBG36F 36V motor: http://www.goldenmotor.com/2) Find a suitable open source motor driver with...

1. Motor selection and control
Log from StrobeTuner
The heart of a strobe tuner is the strobe disk, driven by a small electric motor. It has to spin pretty fast (thousands of RPM), but the only mechanical load is inertia and air drag. The angular speed has to be very accurate and stable. These requirements...

PCB motors suited for laser scanning
Log from prism laser scanner
Abstract: PCB motors seems suited for laser scanning; - speeds seem sufficient - cross scan error is not affected by pcb coils Angular stability needs to be improved but this is seen a relatively trivial issue. Video: Measurement...

Log V: The Pandemic Strikes Back
Log from Open Source Spherical Motor
In a week things move fast! Since my last log the university has shut-down almost entirely (extending and then moving forward the Easter holidays) and the chances of actually manufacturing my design look increasingly slim ... Not least because I'm already...

FIRMWARE V007 IS RELEASED [DUAL CORE ACTIVATED!]
Log from SOLO, A Motor Controller for All Motors
Finally, our breakthrough update is here with parallel processing activation!There is a radical performance enhancement achieved and the FOC loop is running with 140kHz now!To know more please check this link:https://solomotorcontrollers.com/firmware-007-is-released-dual-core-activated/…#servoDrive...

Multi-Axis "Modular" BLDC Driver
Details from Multi-Axis "Modular" BLDC Driver
This board is meant to drive several (the goal is to make the board extendable from 1 to 6+ ESCs) BLDC motors for general use (originally a multi-axis motion simulator). Currently, the board is being designed with the following motors in mind: ...

How to Adjust the Speed of Brushless Motor?
Hacker page by Mark Liu
How to adjust the speed of brushless motor? It is different from the speed regulation of stepper motors (the principle of speed regulation is to rotate a step angle every time a signal is received, so the speed regulation method of stepper motors is...

Scaling
Log from Anti-grav assist unit
The 4 1000kv motors are a bit unwieldy when testing. Figuring out the configuration, and the cost at quantities above the 4...So scaled down to micro core-less motors.In total we have 40 core-less motors, and 80 micro props. :)Each motor can draw .8A...

Multiple boards
Log from Open Rover
So as a result of the change in processors, I have changed the BLDC controller design. This work has been a extrapolation from OpenBLDC, which was my HaD Prize 2014 entry. The design is that the Nucleo will plug into a shield but this will have two sets...

Boards In Action
Log from Powerful Brushless DC Motor Driver/Controller
On this video I do a quick introduction to some of the Power PACk boards and how they can drive a small aerial vehicle motor. In this case, the motor was taken to 2600 Hz at 26V and 3.3A or so, which is in the 85W worth of input power. How much power...
