Speed control of BLDC motor using quadrature encoder

Abdul Rasheed28

I have a requirement to rotate a bldc motor in 0.1rpm (Trapezoidal or FOC). Is it possible using any TI devices? If 'Yes', suggest me one. I would like to control the movement according to the encoder pulses from a quadrature(ABZ) encoder.

Thank you

Abdul,

What is your bus voltage?

Adam,

Thanks for the response. We use 24V power supply.

Do you prefer your own MCU or a device with the control MCU built into the driver?

Adam,

I would prefer a device with the control MCU built into the driver. It will be great if there is an evaluation board with example firmware.

My motor does not have hall sensors. A solution which uses just the motor and a rotary optical encoder is what I am looking for.

In future, this may need to be upgraded to a pulse & direction input compatible drive.

We unfortunately don't have a device that fits your exact need at the moment. I would suggest purchasing a BOOSTXL-DRV832x device and the compatible Launchpad.
