If I was to connect two motors in parallel instead of just the one motor it currently has on each H-Bridge,, would the transistors on the motor controller blow?
I have this motor controller – here is a schematic & table as well:
The lowest pin on the connector is pin 7 ——– The lowest on this connector is pin 1
I am controlling this using my Raspberry Pi, connected to the first 4 pins and last pin of the 7 pin socket – this is not relevant as such, but this outputs 3V3, and controls the H-Bridge.
An individual motor draws less than 0.1A at 6VDC, but on startup and stop can draw up 0.48A These measurements are from a multimeter, which will only take an average anyway.
Each motor has one of these already attached as well:
Here are the transistors:
Q7 – Q10 are 2SC3279 – NPN, can take 2Amps DC, 5Amps 1/100th of a second
Q11 – Q14 are 2SA1300 – PNP, can -2A DC, -5A also for 1/100th of a second
For more info on the controller see here
Here are some data sheets of the relevant transistors:
2SC3270
2SA1300

No, it won't take any more motors .
Just ran a few tests for two motors connected in parallel to the same power supply as would be used by the controller. - here are the results:
Just have to find another one, I guess...
