Can someone help me identify this DC Motor? The controller died, so I want to program a new one with Arduino. The only identifiable #'s on the motor are 1215EF-218J 17x6. 17x6 could be the measurements in mm.
It had three leads coming from it - positive, negative, and one soldered to the outer case (I assume a ground?)
I'd like to be able to determine the voltage needed without damaging it. The original controls were powered by 3 D Cell batteries (4.5 volts)?
Start with 1 cell (1.5V) and see if it gives enough RPM and power. If not try 2 cells and so on (should not be more than 3 cells) till you get the power and speed that you want without overheating the motor.
What will you use the motor for? Will it need to be reversible or will it only run in one direction? We can recommend the right driver if we know that. Arduino cannot drive a motor directly.
I found this that seems to be a close match. https://www.aliexpress.com/item/32948852099.html. (
N20 high torque DC 1.5V micro DC motor). The motor seems to run fine from a AA Battery.
The motor will be used to drive small gears that turn some plastic cannon turrets on a model and yes, it will need to be reversible. I have been prototyping with an Arduino and L293D, but may need to introduce something to drop the voltage to 1.5v.
The original mechanism had limit switches that controlled the amount of forward / reverse functions that I may try to incorporate - right now I have the motor set to delay.
@groundFungus - you helped me with the code for this yesterday on another one of my post! thanks
