    HI,

    I would like to control a 24V DC motor with a Raspberry Pi 3.

    The motor it's from Anaheim Automation (https://www.anaheimautomation.com/manuals/brushless/L010610 - BLY17MDAx Series Users Guide.pdf).

    I already have an external 24V power supply, but I need a convers a 5V circuit which could be controlled from 0 to 5V by a Raspberry.

    What kind of electronic circuit could I make ? And how could I control it by a code ? First time programing in Python.

    Thanks for your help

    Your Datasheet says: external voltage (0.5-5VDC) can be used to control the speed.

    Well if you give 0.5v signal, the motor will run with 400rpm (min) and if you give 5V it will run with the full speed. Do you want control the speed of the motor or you want it to be a constant speed?

    I would like to control the speed, that mean to control a 5V signal

    The fact is, i don't know kind of elctronic circuit could be drived by a raspberry board.

    Check petercuenca link for digital to analog signal with Raspberry.

    If you can output a PWM signal, a D/A convertor circuit can be made to provide the +-0 to 5vdc signal.
