The present invention relates to a method and a system for determining a brushless motor operation detecting signal, in driving a BLDC motor, capable of determining a signal value with a majority decision voting according to a digital logic to ignore a signal disorder due to noise or temporary disturbance for the signal value detected by three Hall sensors mounted on the motor, and applying the signal value to the driving control. According to the present invention, the system for determining a brushless motor operation detecting signal comprises: a motor for providing electric power; one or more Hall sensors for detecting the rev count of the motor; a detecting signal determining unit for receiving the signal value detected by the one or more Hall sensors to determine the signal value with a majority decision voting method according to digital logic; and, a control unit for controlling the rotation of the motor according to the signal value determined by the detecting signal determining unit. |
