Controlling a bldc motor of 24 volts. Which driver is the ideal?

Hello, I have a bldc motor and I want to build the driver for the control because I was investigating and some driver are expensive.

My motor is the next:

Here is the datasheet:

I thought that I can use the driver DRV10983 with Arduino to control the motor.

Which driver do you recommend? I need your help. Thanks

    Hi Oscar,

    What is the goal? Is it to control the motor or understand motor control?

    It appears the DRV10983 may work for controlling the motor, but the BOOSTXL-DRV8301 may be the better choice for controlling the motor and understanding motor control.

    Hi Rick Duncan,

    it is about my thesis and my goal is to control the speed and motor position. It is for that I was thinking about to use the DRV10983. Of course, I am going to analyze your option (BOOSTXL-DRV8301), but its problem is that it is more expensive. If you confirm that I can use the DVR10983 with my motor, it is going to help me a lot.

    Thanks!!

    Hi Oscar,

    The DRV10983 may work, but it provides few options. If you need a motor with slightly more current, it may not work. Also the algorithm is internal to the device.

    The BOOSTXL-DRV8301 allows viewing the control signals from the mcu to the DRV8301 and FETs. There is a bundle available at store.ti.com/launch-f28027f-boost-drv8301.aspx

    In my opinion, controlling the motor position will be easier to do with the BOOSTXL-DRV8301.

    By the way, the motor appears to have internal electronics. If you want to use the either the DRV8301 or BOOSTXL-DRV8301 to control the motor, you may have to remove the internal electronics.
