1. A fan motor control device for use with a fan motor, comprising:

  • a zero-crossing detection unit, which generates a synchronization reference signal after being supplied with electric power;

    a phase control unit being electrically connected to the zero-crossing detection unit for receiving the synchronization reference signal, and generating a phase control signal according to the synchronization reference signal for controlling the fan motor'"'"'s output power and rotational speed;

    an operation processing unit being electrically connected to the phase control unit and generating a processing signal according to the phase control signal;

    a first rectifier element being electrically connected to the operation processing unit and generating a first phase signal according to the processing signal for sending to a first coil unit; and

    a second rectifier element being electrically connected to the operation processing unit and generating a second phase signal according to the processing signal for sending to a second coil unit;

    whereby the fan motor is driven to rotate according to one of the first phase signal and the second phase signal.
