Hbridge And Motor Speed

 
#11

JD - there is a noticeable speed difference b/t a direct connect to the battery and the HB. It's a 185 rpm motor. Connected to the battery directly I'm getting approximately - 180 +/- RPM. Connected through the Hb I'm getting 120 +/- rpm.

PTP - Jumpers = Check!
Power = 6 x AA (Alkaline batteries) with an output of 8.7v. It's powered through ezb v4.

Thetechguru - I removed the jumper and there was no descernable difference. The motor was operating at around 120 rpm.

I think, based on the discussion on this thread, I'm going to buy another, different hbridge and give that a try for comparison. For now, this hbridge will work ok to get the my robot moving.

Thanks again for your help!

Happy New Year!
