    BLDC motor spins in wrong direction after quick deceleration

    The controller is implemented on the microcontroller TMS320F280049 and as the FET-Driver I use the DRV8323RH (both from Texas Instruments). So, the motor controller with a 6-step commutation algorithm is implemented using the Eval-boards from TI which are the LaunchPad LAUNCHXL-F280049C and the BoosterPack BOOSTXL-DRV8323RH (I attached the schematic of the BooserPack). The rotor position of the BLDC-motor is determined via a small magnet which is mounted on the end of the motor shaft and measured by a magnetic encoder
