These look pretty handy: http://www.pololu.com/catalog/product/1187
I'm thinking about ways to add load sensing for drives that don't have this feature yet. Also, I wonder if they are fast enough for PWM signal control? Digikey has some other models of these sensors but it seems for my purposes, the working voltage isn't high enough, or the current range is too wide and some resolution is lost. Current can also be measured with an opamp measuring voltage across a current sense resistor, but I'm worried about a common mode voltage in the hundreds of Volts. Is there away to handle this? -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
