Using DC motors to power computers

Friday, May 11th, 2018

Electric generator experiment from HomoFaciens: The generators I am using are in fact geared DC motors, left over from a project with my sponsor RS Components. The modern abacuses being powered during my experiments are a Raspberry Pi Model, a SIMATIC IOT2020 and an Arduino Uno. A 2x16 characters LCD...

App note: Electrical techniques for using different power sources on vibration motors

Sunday, April 29th, 2018

Application bulletin from Precisionmircodrives on powering vibration motors from different and some cases fluctuating power sources. Link here (PDF) As vibration motors have a wide variety of applications, they are often integrated into systems which have different power sources. A common concern, in terms of power supply, is adjusting the...

Automatic fan controller for server racks

Thursday, March 29th, 2018

Dilshan Jayakody published a new build: In this post we describe fan controller which we designed for our 9U wall mount server cabinet. This fan controller is designed to drive a 12V DC cooler fan with pre-configured intervals or by monitoring the temperature of the server cabinet. Core components of...

UC3844 base motor speed controller

Wednesday, June 24th, 2015

Dilshan Jayakody writes: UC3844 is popular current mode controller which is commonly found on DC-to-DC converter circuits and switch mode power supplies. This motor speed controller is also based on UC3844 and it is specifically design to drive 20V - 24V DC motors. In this given configuration UC3844 produces (approx.)...

Driving a DC motor using software PWM with AVR ATmega

Monday, November 25th, 2013

Davide Gironi writes: This library is an update of the software PWM driver you can find here. This update implements also progressive start / stop features. So, with this one, you can drive up to 4 motors independently controlling: speed, direction, slow start / stop

Precise control of DC motors using an FPGA

Tuesday, September 25th, 2012

[embed][/embed] Chris wrote extensive documentation on how to implement precise control of DC motors using FPGAs. The goal of this project is to build a simple one input, one output system that will control a motor. The control input will come from a trimpot and the FPGA or CPLD’s job...
