Also,I have this driver in order to control my 2 motors.
I want to make a robot with these motors and I want to know what/how many battery/ies should I use in order to power my motors without damage motors or driver(cause says 10A).
I also want
I need your advice.
Thank you very much.
As I said I don’t need so much current,because (for example) I have a transformer (24V and 1 or 2 Amps << 10A of driver) and the speed of motor (with no load) is high and the driver doesn’t get hot(because I have heat sinks ).So, I think the driver I mentioned ,it is a good choice if I don’t use so much current( 26A ).So, what battery do I need?
Go for a 3S 11.1V Lipo at least 2500mAh 20C. Rechargeable (with the right charger), plenty of current if you choose a good one. That will provide enough current to run the motors and probably enough to destroy the driver if you’re wrong about the current your motors will be taking when under load.
A 5V DC-DC converter from that will also run the Arduino (if you have one) and maybe other devices (if you have any).
If you put 24V across your motors, the instantaneous current will rise rapidly to 100A or so if the power source can supply it - you don’t get to choose stall current. The only way to prevent this is to use PWM (at a suitable frequency), and ramp it up to start the motor, not just set to 100%. (or have a current limited supply).
