本發明係關於一種馬達系統，尤其是一種利用數個驅動電路控制單一馬達轉動之馬達系統。The present invention relates to a motor system, and more particularly to a motor system that utilizes several drive circuits to control the rotation of a single motor.
馬達系統之應用對於現今工業技術及自動化的發展扮演著相當重要的關鍵角色。凡有關藉助於動力帶動之技術均少不了馬達系統，例如以馬達帶動載具行走，或者以馬達驅動風扇旋轉等。特別是風扇之應用，由於它能帶動風扇旋轉而引動氣流，進而達到驅風扇熱之目的，因此，將馬達應用於風扇而進行電子產品之散熱乃是業者目前所較為普遍使用的散熱方式之一。The application of motor systems plays a key role in the development of today's industrial technology and automation. All the technologies related to driving by power are indispensable for the motor system, such as driving the vehicle with a motor or driving the fan with a motor. In particular, the application of the fan, because it can drive the fan to ignite the airflow, and thus achieve the purpose of driving the fan heat, therefore, the application of the motor to the fan for the heat dissipation of the electronic product is one of the commonly used heat dissipation methods currently used by the industry. .
如第1圖所示，其揭示一種馬達系統9，包含一第一馬達組91及一第二馬達組92。該第一馬達組91具有一第一馬達911及一第一驅動單元912；該第二馬達組92具有一第二馬達921及一第二驅動單元922。該第一馬達911具有一第一線圈L1電性連接該第一驅動單元912之輸出端，以便該第一驅動單元912控制該第一馬達911轉動。同理，該第二馬達921亦具有一第二線圈L2，且該第二線圈L2連接該第二驅動單元922之輸出端，該第二驅動單元922用以驅動控制該第二馬達921轉動。As shown in FIG. 1, a motor system 9 is disclosed that includes a first motor pack 91 and a second motor pack 92. The first motor unit 91 has a first motor 911 and a first driving unit 912. The second motor unit 92 has a second motor 921 and a second driving unit 922. The first motor 911 has a first coil L1 electrically connected to the output end of the first driving unit 912, so that the first driving unit 912 controls the first motor 911 to rotate. Similarly, the second motor 921 also has a second coil L2, and the second coil L2 is connected to the output end of the second driving unit 922, and the second driving unit 922 is configured to drive and control the rotation of the second motor 921.
請再參照第1圖所示，當該馬達系統9應用於一風扇時，該第一馬達911之轉子及該第二馬達921之轉子分別結合一葉輪，該二葉輪可藉由該第一馬達911及該第二馬達921之帶動而旋轉，以進行電子產品之散熱作業。Referring to FIG. 1 again, when the motor system 9 is applied to a fan, the rotor of the first motor 911 and the rotor of the second motor 921 are respectively coupled to an impeller, and the two impellers can be coupled to the first motor.

由上述可知，該習用馬達系統9可藉由該第一馬達組91及該第二馬達組92獨立運轉控制之方式，使該二個馬達組91及92之間得以相互備援，進而在該二馬達組91、92之一無法順暢運轉或發生故障時，仍可動繼續驅該二馬達組91、92的另一個進行運轉，以便持續對電子產品進行散熱，如此可避免該電子產品因過度積熱，而導致其損壞機率增加，進而可提升散熱運作可靠度。It can be seen from the above that the conventional motor system 9 can independently support the two motor groups 91 and 92 by the independent operation control of the first motor group 91 and the second motor group 92. When one of the two motor groups 91, 92 fails to operate smoothly or fails, the other of the two motor groups 91, 92 can be continuously driven to continue to dissipate heat from the electronic product, thereby avoiding excessive accumulation of the electronic product. The heat increases the chance of damage, which in turn increases the reliability of the heat dissipation operation.
然而，由於上述習用馬達系統9設置有該第一馬達911及該第二馬達921等二個馬達本體，因此，相較於僅設置一個馬達本體之情況，習用馬達系統9將具有整體設置成本、體積及重量增加等缺點。基於上述原因，有必要進一步改良上述習用馬達系統9。However, since the above-described conventional motor system 9 is provided with two motor bodies such as the first motor 911 and the second motor 921, the conventional motor system 9 will have an overall installation cost, compared to the case where only one motor body is provided.

再者，該第一控制組件311係藉由四個信號輸出端分別耦接至該第一驅動組件321之四個電晶體開關M11、M12、M13及M14之各控制端(如閘極端)，該第一控制組件311可產生一組控制信號，該控制信號組並經由該四個信號輸出端饋入四個電晶體開關M11、M12、M13及M14之各控制端，以控制該第一線圈組21之電流流向。Furthermore, the first control component 311 is coupled to each of the control terminals (such as the gate terminals) of the four transistor switches M11, M12, M13, and M14 of the first driving component 321 by four signal output terminals.

The mode is the same as the circuit connection between the first driving component 321 and the first coil group 21, and is not described herein.

Each of the four transistor switches M21, M22, M23, and M24 of the second driving component 322 can control the current flow of the second coil group 22 by the second driving component 322.
另外，請再參照第4b圖所示，該驅動控制裝置3另包含數個保護元件33(例如一保險絲)，該保護元件33之數量與該驅動組件321、322數量相同，且各該保護元件33係串聯設置在電壓源VDD及各該驅動組件321、322之間；例如該電壓源VDD與該第一驅動組件321之間設置一個該保護元件33，而在該電壓源VDD與該第二驅動組件322之間設置另一個該保護元件33。如此，藉由該保護元件33之作用可避免任一該驅動組件321或322在運作中因通過異常之電流而燒毀時，不會影響另一驅動組件321或322之正常作動。In addition, referring to FIG. 4b, the drive control device 3 further includes a plurality of protection elements 33 (eg, a fuse) having the same number of the protection components 33 and 322, and each of the protection components 33 is arranged in series between the voltage source VDD and each of the driving components 321, 322; for example, a protection element 33 is disposed between the voltage source VDD and the first driving component 321 , and the voltage source VDD and the second Another such protective element 33 is disposed between the drive assemblies 322.

再者，在本發明第一實施例中，該第一控制組件311與該第一驅動組件321可藉由積體電路之整合方式共同構成一第一驅動控制IC；同樣的，該第二控制組件312與該第二驅動組件322亦可藉由積體電路之整合方式構成一第二驅動控制IC。Furthermore, in the first embodiment of the present invention, the first control component 311 and the first driving component 321 can jointly form a first driving control IC by integrating the integrated circuits; similarly, the second control The component 312 and the second driving component 322 can also form a second driving control IC by integrating the integrated circuits.
又，該馬達2的各該線圈組21、22之匝數較佳設計為相同；但基於各驅動組件321、322成本及其不同驅動電流的規格選用限制的考量，該馬達2的各該線圈組21、22亦可設計成具有相異的匝數。另外，各該線圈組21、22之線徑亦可依據上述之原則設計為相同或相異。Moreover, the number of turns of each of the coil sets 21 and 22 of the motor 2 is preferably designed to be the same; however, depending on the cost of each of the drive components 321 and 322 and the specifications of the different drive currents, the limitation of each of the coils of the motor 2 is selected. Groups 21, 22 can also be designed to have different numbers of turns. In addition, the wire diameters of the coil groups 21 and 22 may be designed to be the same or different according to the above principles.
舉例而言，一馬達具有0.6安培的額定電流，假設該馬達具有二個獨立且相同匝數、線徑的線圈組21、22，各該線圈組21、22則可容許通過0.3安培的額定電流；倘若市場上僅有0.4安培及0.2安培兩種不同價格及規格之驅動組件321、322可供選擇，該二個獨立且相同匝數、線徑的線圈組21、22即僅能選擇設置二個0.4安培額定電流的驅動組件321、322，以進行該馬達之驅動作業；此外，基於驅動組件321、322成本的考量，該線圈組21、22另一種繞線選擇亦可實施如下：將該第一線圈組21繞製成一具有200匝之線圈，以便容許通過0.4安培的電流，而第二線圈組22繞製成一400匝之線圈(該第二線圈組22使用長度為第一線圈組21之兩倍)，雖然該第二線圈組22因其電阻增加兩倍，而使其容許通過的電流降低為0.2安培，但基本上，該第一線圈組21與該第二線圈組22產生之磁動勢(magnetomotive force)仍能維持相同，此一情況，則可選擇一個0.4安培額定電流之驅動單元及一個0.2安培額定電流之驅動單元，如此可降低驅動單元之成本。For example, a motor has a rated current of 0.6 amps, assuming that the motor has two independent coil sets 21, 22 of the same number of turns, and each of the coil sets 21, 22 can tolerate a rated current of 0.3 amps. If there are only 0.4 amps and 0.2 amps of drive components 321 and 322 of different price and specifications available on the market, the two independent and identical turns and wire diameter coil sets 21 and 22 can only be selected. 0.4 amp rated current drive components 321, 322 for driving the motor; further, based on the cost considerations of the drive components 321, 322, another winding selection of the coil sets 21, 22 can also be implemented as follows: The first coil group 21 is wound into a coil having 200 turns to allow a current of 0.4 amps to be passed, and the second coil group 22 is wound into a coil of 400 turns (the second coil group 22 uses a length of the first coil) 2 times the group 21), although the second coil group 22 is doubled in resistance, the current allowed to pass is reduced to 0.2 amps, but basically, the first coil group 21 and the second coil group 22 Magnetomotive force generated (magnetomotive The force can still be the same. In this case, a drive unit with a rated current of 0.4 amps and a drive unit with a rated current of 0.2 amps can be selected, which reduces the cost of the drive unit.
請再參照第4a及4b圖所示，當本發明馬達系統正常運轉時，該第一驅動組件321及該第二驅動組件322可分別驅動該第一線圈組21及該第二線圈組22，使得該第一線圈組21及該第二線圈組22個別產生交變磁場，並與該馬達2之轉子20之一磁鐵(未繪示)作用產生旋轉，進一步帶動風扇之該葉輪1形成同步轉動。Referring to FIGS. 4a and 4b, when the motor system of the present invention is in normal operation, the first driving component 321 and the second driving component 322 can respectively drive the first coil group 21 and the second coil group 22, The first coil group 21 and the second coil group 22 are caused to generate an alternating magnetic field and rotate with a magnet (not shown) of the rotor 20 of the motor 2 to further rotate the impeller 1 of the fan to form a synchronous rotation. .
然而，當本發明馬達系統之其中一驅動迴路故障而使該故障驅動迴路的線圈組無法正常操作時，如第4a及4b圖所示，由於該第一驅動迴路及該第二驅動迴路在驅動操作上係彼此獨立且互不相關，因此仍可藉由其餘仍能正常運作的驅動迴路驅使該馬達2之轉子20持續轉動。However, when one of the drive circuits of the motor system of the present invention fails and the coil set of the faulty drive circuit fails to operate normally, as shown in FIGS. 4a and 4b, since the first drive circuit and the second drive circuit are driven The operation is independent of each other and uncorrelated, so that the rotor 20 of the motor 2 can be continuously rotated by the remaining drive circuits that are still functioning normally.
