A DC motor controller with control LEDs

Monday, May 15th, 2017

Boris Landoni writes about a new open source project a DC motor controller with control LEDs: It can be controlled through logic levels to set the speed and the direction of the rotation of CC brushed motors and stepper motors; outputs have LEDs indicating the rotation direction. The circuit board we...

Build a simple brushless motor

Wednesday, June 1st, 2016

Matthew Venn built a simple brushless motor, that is available at GitHub: Quite a few things inspired me to make this motor: I’ve been watching Walter Lewin’s excellent 8.02 lectures from his MIT course on electromagnetism, I saw a 3D printed motor on Hackaday, and I’m working on some simple educational...

App note: Sensorless field oriented control of an AC motor

Saturday, July 7th, 2012

PIC 33 microcontrollers  in the motor control series can implement sensorless field oriented control. FOC is a control technique that works with DC and AC induction motors. It operates smoothly over the full speed range, and has full torque when the motor starts. The term “sensorless” does not represent the...

TinyG G-code motor controller

Friday, October 22nd, 2010

TinyG is a multi-axis motor controller for DIY CNC machines. Most CNC controllers receive instructions from a PC, but the TinyG executes G-code directly. By running the Gcode interpreter directly on the chip it avoids the expense and problems of trying to precisely control step timing with a general purpose...
