Claims

A fan main body having a guard body covering the blower blades and the transport wind blades and a DC brushless motor for driving the blower blades, a stand supporting the fan fan body, and a driving circuit part of the DC brushless motor and the driving A motor power supply unit for supplying power to the DC brushless motor via a circuit unit, a rectifier circuit unit for supplying power to the motor power supply unit, a fan operation selection control unit for controlling operation of the CD brushless motor, and the fan operation selection And a power control unit for controlling the supply power from the motor power supply unit supplied to the DC brushless motor as a control signal from the control unit.

A fan, comprising: a motor power supply unit and a power control unit as a variable voltage control unit for controlling a voltage from a rectifier circuit unit as a control signal from the fan operation selection control unit according to claim 1.

An electric fan assembled to the driving circuit portion of claim 1 to control the feeding time from the motor power supply portion of the DC brushless motor to form a power control unit as a bumper control circuit which is controlled as a fan operation selection control unit. .

The driving circuit portion of the DC brushless motor according to claim 1 is turned on each time the switching element is turned on and the other one is turned off whenever the magnetic pole position detection signal of the magnet rotor detected as the detection element changes. The energization overlapping time is sequentially supplied to the other coils in a predetermined direction and order, and the timing of turning off the respective switching elements is calculated by calculating the energization overlapping time corresponding to the set electric angle based on the time interval of the magnetic pole position detection signal. A fan made by delaying time.

The electric fan provided with the setting means which can arbitrarily set the said energization redundancy time of the base | substrate of Claim 1.
