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

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.

Anthony
