I am trying to control a Nema 17 motor with a L298n dual bridge and an Arduino Mega.
My wiring is from this Instructable:
When I connect it to my laboratory power supply the current limitation blinks. Normally when there is too much current needed the LED is all the time on and not blinking.
So I increase the current limit and the motor just starts moving on 3.1A @ 12V (doesn't move if less current) and in the description of the motor on amazon they say "Rated Current/Phase:1.2A" so I am wondering what did I do wrong here?
From my understanding "Rated Current/Phase:1.2A" means that I should run this motor (it's a bipolar stepper motor with 2 phases) not higher than 2.4A?
These are the informations from amazon about this motor:
Led screw diameter: 8mm
Lead screw length: 300mm
Step angle :1.8 degree
Nut material: Brass
Holding Torque: 400mN*m
Thrust(full step): 12.5kg
Rate Voltage: 3.3v
What would be a good voltage to run this motor? I thought 12V is a good idea with.
The motor L298n gets really hot when I run it at 3.2A or more so I think my setup will destroy the dual bridge and / or the motor.
I really appreciate help on this! :-)
