Ok sir
Sorry i can not check the current but i get a photo
Just see this
Here this specification is for 24v 775 Dc motor so i am powering 12v so the current is 20 its correct
The stall current is 40A.
For 2 motors that is 80A, way to much for the BTS7960
So either buy a new driver or just use one motot on each driver
But i am using 12v so current is 20A it is correct or not
If it's a 24V motor it probably will not work very well, if at all with 12V.
It worked
OK but the stall current is still 40A and 80A for two motors
My dubte is if i am use12v the the 40 is decress or not
The specifications for the motor you show in post #44 says 12V, stall current 40A.
Is that the motor you are using or are you using a different motor?
This issue could be resolved very simply and quickly if you would just measure the resistance like I asked
Okay
If the resistance is less than 0.6 ohms, then you will not be able to connect two motors together on one driver
That is 24v
In 775 series two types type 1 is 24v if i am searching i wil get only this type information
In type2 12v no information
Sir it is working but i need a full code to move left right and forward backward
I am using two bts7960 for 4 motor
This is a sample code
int r_en = 2;
int l_en = 3;
//Use PWM pins
int r_pwm = 5;
int l_pwm = 6;
void setup()
{
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
}
void loop()
{
//To enable forward and backward
digitalWrite(r_en, HIGH);
digitalWrite(l_en, HIGH);
//RPM in forward and backward
analogWrite(r_pwm, 255);
analogWrite(l_pwm, 0);
}
I am using arduino mega
Easy enough...
Hi.
Something weird is happening with BTS7960 drive.
I have connected it without vcc logic vontage and it works. I can control velocity and I cannot figure out why is this happening. Could I have problems using it this way?
This is how I have connected it.
Considering the fact that you are not supposed to operate it without Vcc I would say definitely YES.
