# 36D DC Planetary Gearmotor w/encoder - 12V 420RPM
what would be a good motor driver and microcontroller for this dc motor.
I’m planning to use 4 of these motors to make a chassis that can carry 10kg.
Hello @SinghSean and welcome to the RobotShop community,
Are you planning on using one motor controller? Most motor controllers offer two channels so if you want to use one for the 4 motors you would have to wire two in parallel, this means that you won’t be able to control them independently but that’s ok if you just want to have a differential wheeled robot, if you want to use omni or mecanum wheels you will need a motor controller with 4 channels or two motor controllers.
In case you only want to use one motor driver then you will need one that can withstand the continuous current of the motors twice (because you will have two in parallel). In your case this would be around 4A and a stall current of <20A, so you should be able to find a suitable controller in the <10A DC Controllers section of the store. Simply look for one that works on your motor’s nominal voltage (12V) and can withstand 4A continuously. Here’s a nice option:
If you want two motor drivers then simply look for a 12V >2A model. And if you want to control it remotely look for an RC model.
Also, since you mentioned you want that your chassis carries 10Kg, there is a great tool that helps you calculate the specs of your motors:
I hope that helps!
