TMS320F2800137: Universal Motor Control Project & Lab for linear motor

Part Number: TMS320F2800137

Tool/software:

Hi,

Please advise if the Universal Motor Control Project & Lab can be used for linear motors.

If yes, what are the things that need to be changed?

Regards,

    I can be used for linear motor, but we don't have test it for the linear motor. If you want to control the linear motor, you need to know the exact rotor position and switch the moving direction according to the rotor position.

    Hello Yanming,

    Thanks for your response. Can you tell me which specific parts of SW needed to be changed?

    More specifically:

    1. My linear motor has a limited travel range. So I can’t follow the velocity open loop testing on the application. Am I correct?
    2. The linear motor also can’t turn PID in the continue one direction running. What I saw the other drivers will use a sine wave as speed target to make the motor rotate forwards and backwards to limit the total travel distance. Do you have any user manual or example for me to follow?
    3. I also want to have the position loop, do you have any example?

    Regards,

    Need to add new function for linear motor, not only change the codes.

    Correct.

    Currently, No. You can find such reference documentation on some of the engineering website.

    It could be the similar speed or current loop control. You can also get some reference as mentioned above.
