Connecting brushless ESC to air pump #94

I received the parts listed here... However, how would one connect the brushless ESC to the brushed 12V DC motor of the air pump? (3 connectors on ESC vs 2 on the motor)

Since these are all the recommended parts, I assume there is a way to make it work.

Thanks for the help!

Amone the 3 the central one is VCC, white/yellow one is PMW signal, and the last one is GND.

Thank you Arthur. My question relates to the connection between the ESC and the motor itself.

The Air pump comes with a brushed motor (2 connectors), and the recommended ESC connection to the motor is for brushless...therefore 3 connectors there.

Wondering if anyone else has solved this yet.

Pls change to a brushless motor with 3 connects. Then u cld control the speed precisely.

trackoid, I think you mean the actual hard-wiring from ESC to the Air pump , Which is Invasive. (you may need to open the airpump). I rather use a L298 motor driver which is not invasive. Actually I'm in the process of integrate the Microcontroller and L298 together in a PCB . Ihope this help to clarify your concern

I have the same issue connecting the ESC to the Air Pump. Three wires on the ESC and two on the Air Pump. If the solution is to change to a three wire brush-less motor, perhaps the recommended Air Pump should be changed from a two wire model to a three wire model

I suggest you check #62 , That is why I went to his option . I even designed my own pcb . https://user-images.githubusercontent.com/770415/78717961-6aa5f780-78ef-11ea-8836-e46c5e9abc2f.PNG

Idea came up from Adamcullen . I hope this help

Thanks
I guess we all need a brushed ESC instead or do what you and few others have shared here.
