CCS/BOOSTXL-DRV8323RS: BOOSTXL-DRV8323RS compatibility with motors

Part Number: BOOSTXL-DRV8323RS
Other Parts Discussed in Thread: DRV8323

Tool/software: Code Composer Studio

Hi everyone,

I would like to motorize a longboard with this motor driver "BOOSTXL-DRV8323RS". But I don't find suitable motor to this controller. The closest motor I found has this characteristics : Max current 80A, Max voltage 41.5V, 1550W. My controller has the following characteristics : 6-54V and 15A. I am wondering if the motor driver BOOSTXL-DRV8323RS is enaught for this motors. I mean will the driver restrain the capacity of the motor ? .Or do I have to change the motor for another one ? If yes do you have references ? 

Sincerely,

PERRIN Paul-Emile

    Hello!

    Thanks for posting on the MD forum!

    The kit you are mentioning is an Evaluation Module which is intended for evaluation of our DRV8323 in the customer system. The board is not intended to be used in a finished product but instead used as a starting point for making your own PCB that would fit your application the best.

    This being said you could try this kit to get started and spin your motor at lower load. The EVM is designed to support up to 15A and we do not advise using it for higher current as the PCB traces, components, and board connectors have been designed with 15A max in mind.

    Once you have determined if the DRV8323 will work for your application then you could design your own PCB for your longboard.

    Regards,

    -Adam

    Hi Adam,

    Thanks you for you answer, I keep in mind what you said. If we find suitable motor driver, we won't have to design our PCB. This is our goal with my friend, I think we can build motorized longboard with TI controller. The question is "Have you an idea about the ability of the motor to spin with the maximum benefit ?" If we choose a current of 13A and a voltage around 53V. That means 689W of electric power send to the motor equivalent to a speed around 15,5 Miles/h " Will the motor spin as much as posible ? "

    Sincerely,
