BLDC motor driver with PID control option

Hi Team,

I would like to seek assistance for our customer product request.

Here is the requirement for BLDC motor driver with PID control option (IC and EVM):
- Control 10 ~ 25W class motor using Hall sensor.
- Motor driver Vcc: 5V or above
- Motor Voltage, current : 12 or 24V, 2.3A_Max

This is to control the shaking caused by the slight speed difference that occurs at the constant speed of the motor.

I read this document below regarding "Sensored 3-Phase BLDC Motor Control Using MSP430" but there's no BLDC motor driver IC product mentioned:

The nearest I found is TIDA-01585 but is a PI control so I hope you can recommend a more fit to customer request.

Thanks!

Jonathan

  • Hi Jonathan,

    I think TIDA-01585 would still be the best option. Did you try looking into the PID macro in MSP430? I think the code can be modified by adding a derivative control to the existing PI Control.
