I want to build (a pair of) H-bridges to drive my motors, described
thusly (from Tamiya kit # 70097 - two FA-130 motors):
* RPM: 6990-9100 (6990 Max. Efficiency)
* Voltage: 1.5-3V (1.5V Recommended)
* Amperage: .66A
Assuming I'm going to go for the recommended 1.5V, geared down lots and
with small wheels (don't want the little beasty to move faster than I
can run!), I can get TIP31B/TIP32B - I assume that these will be
somewhat overkill, but will work correctly? Considering they're rated
for 3A, I shouldn't be needing heatsinks?
Also, will the 4004 diodes I have sitting in my drawer do the job?
I'll be running a separate power supply/battery for the motors. Is
there anything else I should be doing? (apart from getting an
electronics degree B-)= )
Thanks,
Andrew Merton
