Hey,

I am building an inverted pendulum robot for my final project. Luckily our team has the EDU MINI RC Robot Controller. I am using that as the brains of my project. The problem is that I need to power two dc motors. Here is the specs on the motor I am running if it helps.

1. Voltage Operating Range: 3~9VDC

2. Nominal Voltage: 6V constant

3. No-Load Speed: 160 ± 16rpm

4. No-Load Current: Approx.140mA

5. Rated Speed: Approx.180rpm

6. Rated Current: Approx. 900mA

7. Rated Torque: Approx. 1.2kg-cm

8. Output Power: Approx. 2Watt

9. At Max. Effciency: Approx. 45%

10.Stall Torque: Approx. 5.2kg-cm 11. Motor Speed: 5000 ± 50rpm

12. Gear Ratio: 31:1

13. Shaft Brush: Sintered oiled bronze

14. Gear Material: Steel/Bronz hobbing gears

15. Max. allowable moment Torque : 18 kg-cm

16. Temperature Range: -10C ~ 60C

17. Relative Humidity: 20% to 85%RH

18. Insulatiion Strength: 20MΩ, 500VDC

19. Dielectric Strength: AC250V, 60Sec. Min.

20. Connector: JST PHR-2

I want to use the PWM outs to control this motor the problem of course is that this has to run through a speed controller and I don't have access to anymore Victor 884s and I also believe they wound's work because they draw too much power and are for higher power motors. Is there an Electronic Speed Control/Speed Controller out there I could use that would work with the input of the EDU MINI RC Robot Controller which output would work accordingly for my motors. I have searched for RC hobbie speed controllers for planes and the like but I don't know if this is the same because its a different PWM signal or has low hertz. Any help is appreciated! Thanks guys this is such a great community.
