I need one product to control these two motors

these motor are 24V BLDC, i need motor driver can use FOC control and get motorTorque .

these motor have encoder but they don't have hall sensor

Hi, and thanks for your question!

One of our experts will respond tomorrow.

Thanks,

Matt

Hello,

The first motor seems like it has significantly higher power than the second motor.

Please take a loom at the C2000 microcontrollers for motor control, these devices will be able to interface with your encoder and implement FOC to drive the motor: https://www.ti.com/microcontrollers-mcus-processors/microcontrollers/c2000-real-time-control-mcus/applications/motor-control.html

To implement the power stage, you will need current sensing, a gate driver and external MOSFETs.

This reference design is for 48V, but can give you an idea of the system block diagram: TIDA-01629
This EVM using the DRV8323R can interface with a C2000 launchpad to drive the motor: BOOSTXL-DRV8323RS (however it cannot drive enough power to cover your first motor case, it would just be for evaluation)

Thanks,

Matt

Hello,

You may also reference the BOOSXT-DRV8320RS + LAUNCHXL-F280049C InstaSPIN-FOC solution. It can be found in MotorControl SDK here: https://www.ti.com/tool/C2000WARE-MOTORCONTROL-SDK

You can use this solution to support a 60-V max FOC solution. Furthermore, you can use the InstaSPIN-FOC GUI in the Gallery to evaluate the motor ID algorithm out of the box: https://dev.ti.com/gallery/view/C2000/C2000Ware_MotorControlSDK_InstaSPIN_GUI/ver/1.0.0/

Thanks,
Aaron

Oh, thank God.
I will try these product.
By the way,I remember a product which can change power Voltage when motor power change. TI have this product or similar thing?

Hello,

If you can provide the part number of the product that you are thinking about that can change power voltage when the motor power changes then I can compare and look more into the details and see if we have a part that is similar to it.

Regards,

Anthony

Hi,

Sorry, I lost the relevant information.

If I only need to start the first motor, which drive can control such a high-power motor

Or use DRV8 driver and add electronic amplifier

Regards,

Jerry

Hi Jerry,

The DRV832x devices should be able to drive the first motor as long as you have a good board layout and chose the appropriate external FETs and components that can handle the power requirements. The reason our EVM wouldn't be able to drive your motor to the full capability is because the screw terminal connector to connect the motor phases to our EVM is only rated for 16A max.

Anthony
