What is the purpose of the 10Amp shield for driving the Cytron Power Window Motors w/ 5" Wheels? I have an Arduino kit and want to know that I can control the speed and direction of three of these wheels in unison with one Arduino. Lastly, I know these come in pairs but can they also be bought as a single because I only need three.
Hi there,
Welcome back on the forum.
The 10A shield will act as a ‘‘motor driver and an electronic speed controller (esc)’’. Without the shield, you will never be able to provide the output necessary to drive a motor with your Arduino only.
The microcontroller can send commands or PWM signals to the motor controller. The motor controller will than ‘drive’ the motor.
You can buy these motors separately:

Right One: https://www.robotshop.com/en/power-window-motor-with-coupling-right.html
Let me know if this help you to start.
Do not hesitate if you have any other questions.

Hi! and thanks for your reply. I think I understand but need clarification. If I want to drive three Cytron power window motors all going the same direction and speed at the same time, I thought I could use the left or the right side motors and just change their polarity to ensure that no matter if I got a right or left motor they could spin in whatever direction I wanted. My ultimate goal is to have three of these going the same speed and the same direction (but be able to reverse direction as well), and to be able to adjust the three motors speed and direction in unison. I was hoping that I could buy one motor shield for all three motors. Sorry if this is naive on my part. I don’t necessarily need to use my arduino. I would consider a DC controller as well. Any help in this area greatly appreciated.
You can plug your 3 motors in parallel on the same channel as long as the current required by the motor doesn’t exceed the maximum current output of the motor driver.
There is a left and right window motor. Note that these 2 products use exactly the same motor. The difference between both is the physical shape and orientation of the product.
Hope this helped you.

Thanks again Pjutras.
I was looking at the motor specs and it says <5 amps without load. So I am calculating that 3 motors in parallel would be less than 15 amps with no load. Curious how much a load would increase the amperage? I’m sure there is a calculation for this. Maybe I roll the dice.

Let me know if this is what you were looking for.
Awesome! Thanks for the link. I think I understand it. I am assuming add the amperage from this calculator to the non-load amperage the motor is rated for then multiply times 3 for each motor to see what driver I need.
