I'm making my first wheeled robot using the ez robot v4. I recently connected an h-bridge to my ezb v4 without a problem. The directions were clear and concise. Operating the motors through the ez builder was easy.
My question is this, why does it appear that the motors are running slower than they can? It's a fairly slow rotation. As a test of the set up, I''m running the FingerTech "Gold Spark" 16mm Gearmotors.
Here are the motor specs:
Operating Voltage: 3V - 18.5V (>10V decreases motor life)
Nominal Voltage: 6Vdc
No Load RPM: 11530rpm
No Load Current: 0.09A
Stall Current: 1.3A
Stall Torque: 0.0461kg-cm (0.64oz-in)
Kt: 0.0352kg-cm/A (0.49oz-in/A)
Peak Efficiency: 52%
RPM @ Peak Eff: 9100
Current @ Peak Eff: 0.34A
As a check, i connected a 9v DC 25 motor (I dont have amp info) and it's speed was similar to the more nimble gold spark motor.
Is there something I'm missing (no doubt)? Is there a different way to set-up the hbridge to increase the motors speed?
Thanks for your help.
