Description of the invention: 'Technical field to which the invention pertains. The present invention relates to a control system and, more particularly, to an apparatus and method for controlling a plurality of motor drive components. [Prior Art] The problem of heat dissipation has always been a challenge that all kinds of electronic instruments must face, especially for high-end computer systems with complicated circuits. The heat dissipation system of a high-end computer system usually needs to include multiple fans that operate at the same time to provide sufficient heat dissipation efficiency to prevent the line from malfunctioning due to overheating. In addition to the fan, the heat dissipating system may further include a control wafer for monitoring the fan speed, such as a 1C wafer of the type GMT G768BF. Generally, the rotational speed of the fan is proportional to the operating voltage supplied to the fan by the control wafer, and the control wafer can adjust the operating voltage to change the rotational speed of the fan. Limited by the cost of hardware devices, some cooling systems with multiple fans contain only a single control chip, or the number of control wafers in a cooling system is less than the number of fans, or the cost of a wafer A pin & is responsible for controlling more than two fans. Therefore, "Hai and other political enthusiasm must use a multi-channel switcher to switch between multiple fans' so that each fan is connected in turn to the control chip. Please refer to Figure 1. 1 is a multi-fan heat dissipation system according to the prior art: a heat dissipation system ίο includes a control wafer 12, N fans 14 and a multi-channel switcher 16. N is a positive integer. The plurality of switches 16A in the multi-channel switch 16 are controlled by the CPU of the computer system towel and are periodically turned on or off in turn, and the fans n can be connected to the control wafer 12 one by one. This cycle can be determined by the system or by the user. In general, the period is 2 seconds. The film 12 continuously detects the voltage signals transmitted by the fans 14, thereby determining the respective rotational speeds of the female fans 14, and speeding up the speed of each of the fans 14 with a target speed of 5 1314382. Slow, and thus change the operating voltage of the fan, but the speed of the fan is wrong. In the prior art, the switching time of each switch 16A of the multi-channel switcher 16 is liable to generate slight errors, which causes the above-mentioned misjudgment of the rotational speed, thereby causing the operating voltage of one or more fans to be constantly changing, and the speed of the fan cannot be maintained. stable. In fact, in addition to the heat dissipation system, a similar problem occurs in various systems in which a single control chip controls a plurality of motor drive components (m〇t〇r-driven devices). SUMMARY OF THE INVENTION - The present invention provides an apparatus and method for controlling a plurality of motor-driven components. In accordance with the apparatus and method of the present invention, a single-pin of a single control wafer can control a plurality of motor drives: 曰, 并使 and operate the motor drive components at a stable maximum speed. Cattle According to this (four) - difficult (four) real off age-ready - controller. The first fan of the two fans has a -th = wind, the speed is less than or equal to - the first, the highest speed (Μ%) "· is f = the integer index between the first] the control (four) is the The zth fan is provided and the fan is provided - first, the operating voltage: speed (T,) is higher than the first, · maximum speed (MaXi). The first speed α) is the speed (f), the control is Raising the first fall to the heart goal is equal to the first division, then the spirit and spirit can be obtained by the following detailed description of the invention and the drawings. [Embodiment] 1314382 The purpose is to provide a control for the plural The block of the apparatus and method for motor drive components is in the preferred embodiment 34. Μ is a positive integer. . . . 匕 3 风扇 a fan 32 and a controller of the fan 32 The first tamping fan / speed (8) is a small field equal to - 26th high turn = ^ turn ^ ^ the M of the number of indicators. The controller 34 for the first, · a shoulder shoulder t mesh, 32 - the first, the operation "B) The second speed (T,) is returned to the z-th heart speed (. Γ controller 34 detects ί to: voltage (nine), straight to - voltage upper limit. Operating voltage (V,.), etc. (10) In the case of the use of the electric dust, the upper limit of the electric dust is selectively connected to the controller 24 to the second "most pressure that the solid fan can withstand. For example," it is assumed that the controller 34 can provide The highest: electricity _ upper limit [volts] then the upper limit of the voltage must be less than the equalizer: Although the speed of each fan 32 is proportional to the upper limit of the speed of the taplt 32 ^ 32 proposed by the controller 34. See Figure 4. Figure 4 (In) and Figure 4 are the relationship between the voltage and the nonlinearity. The relationship between the voltage and the nonlinearity is linear and non-linear. As shown in Figure 4, the figure is not, after the _ _ _ a certain value, the fan 32 and 'even The controller 34 provides a higher operating voltage to the fan & fan & 8 1314382. The maximum speed. In addition, the second maximum electrical operation of the saturation voltage described above. If the control chip is provided to the fan 32, the fault is: "Saturated power, fan% may be burnt due to excessive temperature. ===The target speed set by each fan 32 is greater than the respective 34. The fan 32 cannot reach the target speed. The operating voltage is 5 volts, the first wind is ^ the mother is 5,000 rpm and the speed is 10 volts. And, the highest voltage that the first fan can withstand according to the present invention, the maximum voltage used is 7 volts. The root clock _ turn. After detecting the first wind speed, after 10,000 revolutions per minute, the controller 34 The speed of the fan is lower than the mother's minute operation. When the controller 34 provides the operation of the fan and the second fan, the fan and the second fan are at the highest speed every minute ^ _ turn after the first device 34 will continue to be upgraded to provide the second speed $ knife clock 10000 rpm 'control the operating voltage is equal to 7 volts. Because of the operating voltage of the two fans, until the stability is maintained at 5 rpm, and the control and the second fan The operating voltage of the fan will also be turned at 7 & The maximum fan speed is not necessarily the same for the first fan and the second fan. Assume that the maximum speed per minute of the touch and 7000 ^ 2 fans per minute is the operating voltage of the rotating speed of 5 volts, the operating voltage of the first fan corresponding to the speed of 5000 revolutions per minute is 8 volts, and the second fan corresponds to At 7000 per minute, the first fan and the second fan can withstand a maximum voltage of 137 volts for the 1,314,382 volts, and 14,000 rpm for the mother. After detecting η ί—the target speed of the fan is _〇, the speed of the second fan of the controller is lower than ί5 2 special 5 'the first fan is the maximum speed, ·=—5Ξ=ίΓΓ ^ a fan mother minute The rotation speed of 5_ turns is two to five revolutions. Since the operating voltages of the first fan and the second fan are stably maintained at 7gr, respectively, as shown in FIG. 3, the controller 34 may include a channel cut.
