i created this 28BJY-48 stepper motor circuit with a basic stepper motor driver, and it has heating up a little but too much after a few minutes of use. i also noticed the drivers part itself was a bit hot too. what is wrong?
Please post a schematic of the circuit rather than a picture from which the connections and components used cannot be determined
Please post your full sketch, using code tags when you do. This prevents parts of it being interpreted as HTML coding and makes it easier to copy for examination
In my experience the easiest way to tidy up the code and add the code tags is as follows
Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.
I will take a SWAG and say your current setting is to high.
Heating is absolutely normal, due to motor current flowing through the resistance of the motor wiring.
"Too much" for a motor is typically > 80 degrees C, far too hot to touch, or smoke actually rising from the motor.
thanks, it was a long time since i got my hands on any electric motor, i did not know it heating was normal.
@gilshultz This driver doesn't have current control.
Motor heat is directly related to motor supply voltage.
Stepper motors draw the same current all the time.
Actually this motor/driver combo uses slightly less current when it's spinning.
You can avoid the motor from heating up by switching the coils off when the motor is not turning.
