microzone Posted April 30, 2006 Report Share Posted April 30, 2006 Thanks, I have read the article called Pulse Width Modulation written byBy Michael Adler and Tim Surtell at http://www.eleinmec.com/article.asp?28. May I know the mean of "The motor will work perfectly well, provided that the frequency of the pulsed signal is set correctly, a suitable frequency being 30Hz."? How do I set the frequecy to be 30Hz and how do I know my frequency is at 30Hz after setting? Thanks for your kind help. :D Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 30, 2006 Report Share Posted April 30, 2006 A frequency counter instrument will show its frequency. My digital multimeter has an accurate frequency counter function. Quote Link to comment Share on other sites More sharing options...
