HELP - Fluid-o-tech BLDC Motor

Hello all,
Trying to figure out how to run a 24v BLDC motor, has its own internal driver board. Is it possible to use arduio as a scope to control the speed of the motor.
Here is the original data sheet.

I figure the bottom left image would be the one i use to configure the hardware to the arduino.

Would greatly appreciate any advice on programming and hardware setup

I moved your topic to an appropriate forum category @H3cT1cL3o.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

I am not sure what you are asking, a scope is a test instrument not a control device.

Sorry, if my question was not clear, I was hoping to use the arduino as the scope and controller. Reading the speed output from the motor and also controlling the speed input (voltage).

That is not possible with standard equipment.

Is this what you want to say? I was hoping to use the arduino as the controller which reads the speed of the motor and controls its speed. The answer to that would be yes. You will need to design an interface circuit.

Thats exactly what I was trying to do, im a bit of a noob, can you give me an example or what i should be searching for to make the interface circuit.

To give some direction to the answers, exactly what do you want to do with the motor?

Mainly for diagnosing the pump for issues. And to get an understanding of the control circuits and programing.

But eventually i will be using one inside a coffee machine with variable speed control for pressure profiling, this one will use a pressure sensor to vary the speed to keep consistent pressure or vary the pressure manually and eventually with a saved pressure profiling curve

Sounds like a great project. The biggest problem I see is generating the control voltage from an Arduino.

Unless I've miss understood the specifications, isnt the speed control input is only 5v I thought the would be within the specs of the arduino although it says max 4amp.

Maybe im in over my head :face_with_spiral_eyes:

Yes, but 0 to 5. NOT just 0 and 5. The usual Arduino does not have that capability. You will have to design and built something to give you 0 to 5 or find an Arduino that can do that.

Ok thank you, would a DAC be what im looking for?
Something like this?

Looks like it would do the job, along with a proper power supply.
