Details from Raspberry Pi and BLDC Gimbal Motor
This example shows how to control motor speed, torque and angle of BLDC gimbal motors using the Field Oriented Control (FOC) algorithm (or not) in C++/Python. "A Guide to Using BLDC Motors (Gimbals) with OpenSource PCB SaraKIT: A Comparison of Stepper...

Compliant robotic gripper
Details from Compliant robotic gripper
If you are interested in BLDC driver from this project fill this form: https://forms.gle/eHPAsbJ77hMaUC4FA Goal of this project was to create gripper that could sense forces by measuring current thru BLDC motor. It is based on my S-Drive BLDC driver...

Tiny BLDC
Details from Tiny BLDC
The Tiny BLDC board measures 1.3" x 0.9" (33 mm x 23 mm). The reason why we can make a BLDC motor driver so small is because PAC5223 has pretty much all the circuitry required to drive the power FETs. These components are:3 phase pre drive power stage3...

RC Car - LEGO Powered by Raspberry Pi with SaraKit
Details from RC Car - LEGO Powered by Raspberry Pi with SaraKit
Story I've always enjoyed building with Lego bricks, but rather than following the provided instructions, I preferred bringing my own ideas to life. Recently, I've delved into the world of Raspberry Pi, appreciating its capabilities, as well as being...

Find out more at: https://source-robotics.com/ The Problem Today every engineer, maker, and tinkerer can get access to a decent 3D printer for less than 300$ and start creating. Many of those people that have 3D printers also want to play and experiment...

Using BLDC motor in low speed
Details from Using BLDC motor in low speed
In this project, we are trying to drive a BLDC motor in very low speed. This means we need to have a very low PWM values update rate. However, the PWM values update rate is constant, the rotating speed of motor's rotor may not being what you expected....

High performance dorm room CNC
Details from High performance dorm room CNC
The main goals of this design are:Design has to be cheap(ish); parts i can get for free through contacts won't be seen as costs, as is stuff like the water-jet cutter i can use for free at my university. Can fit under my bed for storage when not...

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...
