Description
本創作係一種三相馬達之結構改良，主要係令三相馬達可以經由單相交流電予以提供電力而驅動者。This creation is a structural improvement of a three-phase motor, mainly to enable a three-phase motor to be powered by a single-phase alternating current.
由於國內家庭用電都是採用110伏特電壓的單相交流電，因此居家電器用品也都是以此一規格進行設計的，所以在馬達設計中也是只能採用單相馬達做為驅動之動力，然而單相馬達的體積大、成本較高，又具有噪音大、效率較差、電流較高的缺點，故單相馬達多見於1馬力以下的家用小型電器，否則電能的損失很大。Since domestic household electricity is a single-phase alternating current with a voltage of 110 volts, home appliances are also designed with this specification. Therefore, in the motor design, only a single-phase motor can be used as the driving force. Single-phase motors are bulky, costly, and have the disadvantages of high noise, poor efficiency, and high current. Therefore, single-phase motors are more common in household appliances below 1 horsepower, otherwise the loss of electrical energy is large.
因此本案創作人曾以三相馬達設置啟動電容的技術創作出可以單相交流電驅動三相馬達運轉之技藝。然而由於在技術上係以三相馬達第一相接口端及第二相接口端連接單相交流電的兩電源線，再以一啟動電容的兩端分別連接在單相交流電的一電源線及第三相接口端，促使啟動電容產生的分相可以相位差驅動三相馬達運轉(啟動電容使得單相交流電的電壓和電流產生90度的相位差，可在三相馬達定子與轉子之間產生旋轉磁場)。其雖然可以達到降低成本、提高效率之目的，但由於在設計上較為簡單且必須考慮啟動電容驅動三相馬達開始運轉時之阻力，因此啟動電容的電容值都較大而耗電，所以在驅動三相馬達運轉後就會因為啟動電容的 電容值過大而耗用較多的電力，致使採用三相馬達的省電效能受到影響。Therefore, the creator of this case used the technology of setting the starting capacitor with three-phase motor to create the technology that can drive the three-phase motor with single-phase AC. However, since the first phase interface end and the second phase interface end of the three-phase motor are connected to the two power lines of the single-phase alternating current, the two ends of the starting capacitor are respectively connected to a power line of the single-phase alternating current and the first The three-phase interface terminal causes the phase separation generated by the starting capacitor to drive the three-phase motor in phase difference (the starting capacitor makes the voltage and current of the single-phase alternating current generate a phase difference of 90 degrees, and can generate a rotation between the stator and the rotor of the three-phase motor magnetic field). Although it can achieve the purpose of reducing cost and improving efficiency, it is simple in design and must consider the resistance when the starting capacitor drives the three-phase motor to start running. Therefore, the capacitance of the starting capacitor is large and consumes power, so the driver is driven. After the three-phase motor is running, it will be because of the starting capacitor. The capacitance value is too large and consumes a lot of power, so that the power saving performance of the three-phase motor is affected.
因此本創作人以其從事馬達專業設計、製造的經驗，積極研發改良，在各方條件的審慎考量之下，終於開創出本結構之組成，將可完全解決習用之各項缺失。Therefore, the creator actively develops and improves the experience of designing and manufacturing the motor professional. Under the careful consideration of various conditions, the creator finally creates the composition of this structure, which will completely solve the various shortcomings of the application.
本創作係一種三相馬達之結構改良，主要係包含有設置離心開關的三相馬達、啟動電容、運轉電容及兩電源接線，其中兩電源接線分別連接三相馬達的第一相接口端及第二相接口端，令啟動電容、運轉電容的兩端各別連接同一電源接線及第三相接口端，且啟動電容與第三相接口端間係經由離心開關所連結，因此在實施後將可提供下述之效益：由於本創作的三相馬達係以兩電源接線分別連接三相馬達的第一相接口端及第二相接口端，令啟動電容、運轉電容的兩端各別連接同一電源接線及第三相接口端，且啟動電容與第三相接口端之間係經由離心開關所連結，因此當兩電源接線經由單相交流電的兩電源線連接供電後，可令單相交流電的電壓和電流經由啟動電容、運轉電容而產生90度的相位差，促使三相馬達定子與轉子之間產生旋轉磁場。因此在旋轉磁場作用下，三相馬達轉子中產生感應電流，感應電流與旋轉磁場互相作用產生電磁轉矩，所以可以促使三相馬達順利運轉。而當三相馬達的轉速到達離心開關額定值後即會跳脫而斷開啟動電容，形成單相交流電僅由運轉電容供電至三相馬達的狀態，因此可藉由運轉電容的電容值小於啟動電容的電容值的特性，達到降低電流的損耗而省電的目的。This creation is a structural improvement of a three-phase motor. It mainly consists of a three-phase motor with a centrifugal switch, a starting capacitor, a running capacitor and two power connections. The two power connections are connected to the first phase interface of the three-phase motor and the first The two-phase interface terminal connects the two ends of the starting capacitor and the running capacitor to the same power supply wiring and the third phase interface end, and the starting capacitor and the third phase interface end are connected via a centrifugal switch, so that after implementation, The following benefits are provided: since the three-phase motor of the present invention is connected to the first phase interface end and the second phase interface end of the three-phase motor by two power supply wires, the two ends of the starting capacitor and the running capacitor are respectively connected to the same power source. The wiring and the third phase interface end, and the starting capacitor and the third phase interface end are connected via a centrifugal switch, so when the two power supply wires are connected and powered by the two power lines of the single phase alternating current, the voltage of the single phase alternating current can be made. And the current generates a phase difference of 90 degrees via the starting capacitor and the operating capacitor, causing a rotating magnetic field between the stator and the rotor of the three-phase motor. Therefore, under the action of the rotating magnetic field, an induced current is generated in the three-phase motor rotor, and the induced current interacts with the rotating magnetic field to generate electromagnetic torque, so that the three-phase motor can be smoothly operated. When the speed of the three-phase motor reaches the rated value of the centrifugal switch, it will trip and disconnect the starting capacitor, forming a single-phase alternating current that is only supplied by the running capacitor to the state of the three-phase motor, so the capacitance of the running capacitor can be less than The characteristics of the capacitance value of the starting capacitor are used to reduce the current loss and save power.
本創作的三相馬達係直接以其兩電源接線連接單相交流電 的兩電源線即可使用(例如三相馬達兩電源接線構成插頭連接單相交流電之插座的設計)，因此可以廣用並取代居家電器用品的馬達，達到提高效能、降低能源損耗的目的。The three-phase motor of this creation is directly connected to single-phase AC by its two power connections. The two power cords can be used (for example, the design of a three-phase motor and two power cables to form a plug for connecting single-phase AC power), so that the motor of the home appliance can be widely used and replaced to improve performance and reduce energy consumption.

為使 貴審查人員能確實明瞭本創作之結構組成及其所能達成之功能效益，餘下，茲配合圖式列舉實施例，詳細介紹說明如后：本創作係一種三相馬達之結構改良，主要係包含有設置離心開關2的三相馬達1、啟動電容3、運轉電容4及兩電源接線5(如第一、二圖所示)，其中兩電源接線5分別連接三相馬達1的第一相接口端11及第二相接口端12，令啟動電容3、運轉電容4的兩端各別連接同一電源接線5及第三相接口端13，且啟動電容3與第三相接口端13間係經由離心開關2所連結，俾可在兩電源接線5經由單相交流電的兩電源線供電後，令啟動電容3、運轉電容4產生的分相可以相位差驅動三相馬達1運轉，並在三相馬達1轉速令離心開關2跳脫而斷開啟動電容3後，由運轉電容4持續提供相位差之供電狀態者。In order to enable your reviewers to clearly understand the structural composition of the creation and the functional benefits that can be achieved, the rest will be accompanied by a diagram to illustrate the examples, and the detailed description will be as follows: This creation is a structural improvement of a three-phase motor, mainly The utility model comprises a three-phase motor 1 with a centrifugal switch 2, a starting capacitor 3, a running capacitor 4 and two power supply wires 5 (as shown in the first and second figures), wherein the two power wires 5 are respectively connected to the first phase of the three-phase motor 1 The phase interface end 11 and the second phase interface end 12 respectively connect the two ends of the starting capacitor 3 and the running capacitor 4 to the same power source wiring 5 and the third phase interface terminal 13, and between the starting capacitor 3 and the third phase interface terminal 13. It is connected via the centrifugal switch 2, and after the two power supply lines 5 are powered by the two power lines of the single-phase alternating current, the phase separation generated by the starting capacitor 3 and the running capacitor 4 can drive the three-phase motor 1 to operate with a phase difference, and When the three-phase motor 1 rotates to cause the centrifugal switch 2 to trip and the starting capacitor 3 is disconnected, the operating capacitor 4 continues to provide the phase difference of the power supply state.
因此當三相馬達1的兩電源接線5經由單相交流電的兩電源線連接供電後，可令單相交流電的電壓和電流經由啟動電容3、運轉電 容4而產生90度的相位差(如第三圖所示)，促使三相馬達1的定子與轉子之間產生旋轉磁場。因此在旋轉磁場作用下，三相馬達1轉子中產生感應電流，感應電流與旋轉磁場互相作用產生電磁轉矩，所以可以促使三相馬達1順利運轉。而當三相馬達1的轉速到達離心開關2額定值後即會跳脫而斷開啟動電容3，形成單相交流電僅由運轉電容4供電至三相馬達1的狀態，因此可藉由運轉電容4的電容值小於啟動電容3的電容值的特性，達到降低電流的損耗而省電的目的。Therefore, when the two power supply lines 5 of the three-phase motor 1 are connected and powered by the two power lines of the single-phase alternating current, the voltage and current of the single-phase alternating current can be made through the starting capacitor 3 and the running power. The phase difference of 90 degrees (as shown in the third figure) causes a rotating magnetic field to be generated between the stator and the rotor of the three-phase motor 1. Therefore, under the action of the rotating magnetic field, an induced current is generated in the rotor of the three-phase motor 1, and the induced current interacts with the rotating magnetic field to generate an electromagnetic torque, so that the three-phase motor 1 can be smoothly operated. When the rotational speed of the three-phase motor 1 reaches the rated value of the centrifugal switch 2, it will trip and disconnect the starting capacitor 3, forming a state in which the single-phase alternating current is only supplied from the operating capacitor 4 to the three-phase motor 1, so that it can be operated The capacitance value of the capacitor 4 is smaller than the capacitance value of the starting capacitor 3, and the purpose of reducing the current loss and saving power is achieved.
再者，由於三相馬達1啟動運轉時係由啟動電容3、運轉電 容4產生的相位差而驅動三相馬達1運轉的，而啟動電容3、運轉電容4的兩端是各別連接同一電源接線5及第三相接口端13呈並聯狀態(啟動電容3與第三相接口端13間再經由離心開關2連結)，因此在電容並聯總電容量(電容值)為各電容量之和的原理下，啟動電容3係可與運轉電容4具有相同的電容值，或令啟動電容3的電容值小於運轉電容4，其中又以啟動電容3的電容值大於運轉電容4的電容值為最佳，俾可設計出以最小電容值的運轉電容4提供三相馬達1持續運轉的電力，達到最省電的效果。Furthermore, since the three-phase motor 1 is started, the starting capacitor 3 is operated. The phase difference generated by the capacitor 4 drives the three-phase motor 1 to operate, and the two ends of the starting capacitor 3 and the running capacitor 4 are connected to the same power supply terminal 5 and the third phase interface terminal 13 in parallel (starting capacitor 3 and Since the three-phase interface terminals 13 are connected via the centrifugal switch 2, the starting capacitor 3 has the same capacitance value as the operating capacitor 4 under the principle that the total capacitance (capacitance value) of the capacitors in parallel is the sum of the capacitances. Or the capacitance value of the starting capacitor 3 is smaller than the running capacitor 4, wherein the capacitance value of the starting capacitor 3 is greater than the capacitance value of the running capacitor 4, and the operating capacitor 4 with the minimum capacitance value can be designed to provide the three-phase motor 1 The continuous operation of electricity achieves the most energy-saving effect.
