I recently had to replace my motor in my air cooler. I decided to buy a BLDC motor. All seems to work fine. Motor is running. Oscillation, water pump all works fine. However, I am unable to fix the speed controller part. I am attaching my existing speed control design and what my new motor guy forwarded. Let me know what should I do.
Also my additional findings. There was a 5 core wire running to my old motor. (If further explanations are required , let me know)
Blue color - Phase. it is connected to my new motor phase
I see the following observations when I connect my new motor's neutral to the other colors. Totally there are 3 speed settings , 1,2,3 . 3 is highest
Red wire - runs in speed 1 setting, switches off in other speed settings
Yellow wire - runs in speed 3 setting, but slow. switches off in other speed settings
black wire - runs in full speed at speed 3. switches off in other speed settings
white wire - doesn't run at all. but it gives a small motion initially and stops.

below is my conversation with the new motor guy which also has the design of speed control he suggested
