Part Number: DRV11873
Dear Sir,
I am using a DRV11873EVM to connect a 12 pole BLDC motor. And apply power to the H1 header, the motor starts quick smooth.
But when I adjust the R6 Potentiometer counter-clockwise to increase the speed , the motor was getting fast and out of control. Although I stop adjusting the R6 , the rotation speed keep increasing.
I end up Turning off the supply voltage to stop the motor.
May I know what happened to this? is anything wrong? Thanks.
