Gecko has some good recommendations for power supply on their website. It appears that the author of the .pdf you reference has followed these guidelines.
The file on gecko's site that you should read is called "stepper motor basics.pdf" in the support section. FWIW. I am also in process of whipping up a supply for my geckos. I am converting an old pcb router to use new motors. I am fortunate that it has a very hefty toroidal transformer that will work with the new motors. Now I just need to order some large (10,000uf) caps. There were a pair of large caps in the old power supply but they leaked. As far as where to get the transformer, I would check out some of the surplus places on the web like: www.halted.com www.herbach.com and of course, ebay On Sunday 19 August 2007 9:13 am, John Thornton wrote: > Have any of you built your own power supplies for stepper drives? > > I have seen some examples that use a Plitron transformer. > Where is a good source for them? > > Is it common to oversize the capicity of the transformer? > > For stepper motors is there a common voltage for the transformer? > I notice that the Automation Direct power supply is 32 volts. > Is this a common voltage? > > I found this link for basic power supply design > http://www.campbelldesigns.com/files/power-supply-part-1.pdf > > Is this pretty standard design? > > Sorry for so many simple questions > > Thanks > John ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
