Therefore, in the present embodiment, the fan system fan whose circuit module i is electrically connected is connected to the operating voltage 6, and at the moment when the voltage 6 is energized, the operating unit 3 generates a running signal, which operates. The system represents the signal that the fan starts to start, and the driver chip 4 receives its operation signal and generates a soft start signal, and the soft start signal drives the wafer 4 to the transistor Q1 of the second connection portion RD. In the state, and at the moment of energization, the first capacitor C1 of the operating unit 3 generates a momentary short circuit, and the stable voltage of +6V is first sent to the third connecting portion VTH' and then the stable voltage of +6V is applied to the first The capacitor C1 is slowly charged, and during the charging process, the voltage of the third connecting portion VTH is slowed down by 7 M377006, wherein the lower the voltage received by the third connecting portion VTH as described above, the circuit mode The fan system of the group 1 is electrically coupled with the higher speed of the fan drive coil, and the voltage of the third connection part VTH is slowly decreased. Therefore, the fan speed is also slowly increased, and the fan is started with a soft start. The mode is started until the voltage of the third connecting portion VTH is less than 1.65V, and the fan speed is the full speed operation. In the embodiment, the voltage of the third connecting portion yTH has the following calculation mode: the third connecting portion The voltage value VVTH of VTH is approximately equal to [(R3//R2)*6]/[(R3//R2)+R1]<1. 65V' The electrical voltage value Vvth of the third connection part VTH is right 1 65V-4. 65V is a controllable interval, and the voltage value of the third connection part VTH is Wth<1.65V, the fan runs at full speed. Therefore, the circuit module 1 with soft start function can be effectively used. Reducing the current value when the fan is started can avoid the fan system from running normally when the fan starts up too much, and the fan system can not operate normally. At the same time, it can avoid the problem of excessive noise caused by excessive speed of the fan immediately at full speed. Moreover, after the fan system fan electrically coupled to the circuit module 1 of the embodiment is activated by the soft start signal, the transistor Q1 of the driving chip 4 in the second connecting portion rib is turned on. The voltage value Wth of the third connection portion VTH can be calculated by the aforementioned calculation method 'the voltage value Vvth of the third connection portion VTH is approximately equal to [(R3//R2)*6]/[(R3//R2HR1]<1 65V, and the fan of the fan system is running at full speed, and during the normal operation of the fan at full speed, the fan will have a stall phenomenon, and the stall phenomenon is caused by the fan system in normal operation. When a fan stops rotating due to a fault, it is called a 1 8 M377006 blocking phenomenon. When the stalling phenomenon occurs, the fan system generates a rotating current. If the blocking current is too high, the temperature will be caused. The phenomenon of high boost and fan burnout's and the height of the stall current is determined by the voltage value Vvth of the third connecting portion VTH, and the higher the voltage value Vvth of the third connecting portion VTH is, the smaller the stall current is. Therefore, in this embodiment, when the fan fails When the rotation is stopped, the operation signal generated by the operation unit 3 is transmitted to the driving chip 4. At this time, the operation signal represents a signal that the fan is malfunctioning, and the driving chip 4 generates a rotating current signal 'and its stalling The current signal is such that the transistor Q1 of the driving chip 4 in the second connecting portion rib is turned off, and when the second connecting portion rib is in the off state, the voltage value VvTH of the third connecting portion VTH is calculated as R2. *6/(R1+R2)>1. 65V 'Therefore, when the fan generates a stall phenomenon, the voltage value Vvth via its third connection portion VTH will increase instantaneously to minimize the stall current. When the circuit module 1 generates a stall phenomenon, the voltage value Vvth of the third connecting portion VTH can be controlled to obtain a third difference by adjusting the resistance values of the first resistor and the second electric resistor R2. The voltage value VVTH of the connection portion VTH is such that the drive chip 4 of the circuit module 1 generates a stall current signal when the fan of the fan system is blocked, to increase the voltage value Vvth of the third connection portion VTH to avoid the fan system. Fan blocked current The problem of large temperature increase is high, and the problem of fan burnout is reduced. Continued to Fig. 4, it is a circuit diagram of the fan system with circuit module 1 of the present invention, and the drive chip 4 is mainly in this embodiment. Distinguishing between a first connecting portion HB, a second connecting portion rib, a third connecting portion VTH, a ninth: connecting portion vcc and a fifth connecting portion (10), and having at least a sixth connecting portion cake, The first connection portion _ is connected to the sensing unit 5, and the second connecting portion RD and the third connecting portion VTH are connected to the third resistor R3 and the first resistor R1 included in the operating unit 3 The second resistor is disconnected from each other, the fourth connecting portion VCC is picked up from the operating voltage 6, and the fifth connecting portion is trapped at the ground. The sixth connecting portion is a motor 7, wherein The sensing unit 5 is a magnetic field bottle of the outside world, and the sensing unit 5 detects that the external magnetic field is generated, and then outputs an inductive signal to the crane chip 4 and drives the motor 7 via the sixth connection portion of the driving chip 4, and The fan is turned on and the power of the light 6 is turned on and the operating voltage is 6 Between the operation unit 3 and the operation signal 3, the drive chip 4 generates a soft start signal via the operation signal thereof, and the transistor Q1 of the second connection portion RJ of the drive wafer 4 is turned off. At the moment of power-on, the first capacitor C1 of the operating unit 3 generates an instantaneous short circuit, and the stable voltage of +6V is first sent to the third connecting portion VTH, and then the stable voltage of +6V is slow to the first capacitor C1. Charging, and during the charging process, the voltage of the third connecting portion VTH is slowly decreased. Therefore, the fan speed is also slowly increased, so that the fan is started in a soft start manner when the fan is started, and the fan can be avoided when the fan is started. If the starting current is too large, the fan system will not operate normally. At the same time, the problem that the fan is too high and the excessive speed will cause excessive noise, and the fan will run at full speed. In the case of the fan, there is a stall phenomenon, and when the stall phenomenon occurs, the fan system generates a rotating current. Therefore, when the fan stops rotating due to the failure, the driving chip 4 is operated via the operating unit. The signal generates a rotating current signal, and the blocking current signal drives the wafer 4 to the transistor Q1 of the second connecting portion RD to be in a wearing state, and the voltage value Vvth of the third connecting portion VTH is instantaneously increased. In order to minimize the stall current, to avoid the phenomenon that the fan system's fan blocking current is too large and the temperature rise is high, causing the fan to burn. As described above, the present invention is a fan system circuit module, which has the following advantages: 1. When the fan is started, it is started by a soft start mode, which can prevent the fan system from being operated normally due to excessive fan starting current when the fan is started; The fan start-up speed is slowly increased to avoid the problem of excessive noise caused by excessive full-speed start-up speed immediately. 3. When the fan is blocked, the stall current can be minimized to avoid the fan system being too large. The temperature increase is high^caused to cause the fan to burn out; 4. The application of the electronic 70 is less than 'effectively reduce its additional cost; According to the above, it is only a best embodiment of the creation, but the creation The characteristics of the secret are limited to this, and any person who is familiar with the artist's 'changes or repairs' that can be easily thought of in the field of creation should be covered by the following patents.
