I was looking for L298n, but the datasheet says, that it can output 2A max, but my motor needs around 2.8A. I would like to operate the motor at around half of the maximum power it can provide (I need around 150 RPM and 0.7Nm.
Would it be possible to use the L298n?
Also what kind of power source should I use, if the motor says, that it operates at around 3V.
And for the last part, I need to find those components in Spain/Madrid
No, All motors draw max. current every time they start up.
The rated voltage is kind of a misnomer. It is the maximum voltage that produces the max. current if connected directly without a controller. Of course you don't want to do that as the speed would be very very low.
When using a controller it uses PWM to keep the current within spec while using voltages up to 20 times higher than the rated voltage. This greatly increases speed and torque.
Typical power supplies used are 12v - 36v and higher.
I am using a 36v power supply with my NEMA 17 stepper also rated at 2.8A and 3v.
As my project needed the extra torque to avoid missed steps under load.
Perfect, thanks for the quick response, I wasn't really sure, so now I know, that I have to look for different one.
I found TB6600 digital stepper motor driver. That one could work easily right?
