【先前技術】 内置式永磁（Interior Permanent Magnet，IPM)馬達 因具備優良之操控性能與運轉效率，所以逐漸取代傳統之， 馬達。内置式永磁馬達除了在家電的應用日趨廣泛外，也 朝者工業產品應用之發展方向邁進。[Prior Art] Built-in permanent magnet (IPM) motors have gradually replaced traditional motors with excellent handling and operating efficiency.

習用之内置式永磁馬達由於本身之轉子上的永久磁石 具有很強的磁性，對於鐵質細小的零件、工具或者是鐵屑 等雜物會產生吸附，如果不慎讓雜物吸附於轉子上而裝置 於馬達内。卩，將會造成馬達運轉異常甚至是造成意外狀況 發生。因此’以往在馬達組裝流程或者是對已經充磁之永 之儲存、運料過程，皆須姉安排。為了解決前 :體:能將未充磁之磁石先行欢八馬達轉子 程之安排‘曰則將有助於簡化整雜馬達組裝流 操作之产:：?其組裝安全性’同時更可以滅少未來馬達 200828734 有鑑於此，國際間現有的趨勢都是朝向此方向來進行 技術之改良與突破，不過這種先將轉子置於馬達内再進行 充磁的方式在馬達轉子定位技術上，仍有改善空間。例如 美國公開專利U.S. 20040070361所揭露之一種針對集中繞 線式馬達之定子線圈作為充磁線圈，並依轉子之磁石容置 槽與定子線圈之配合，定義固定之相對移動角度以進行充 磁。雖然該技術可以利用定子繞線進行充磁，然而其缺點 需要外加偵測轉子之位置感測器與相關之機構才能夠進行 • 轉子定位。 此外，又如美國專利U. S. Pat. No. 5, 424, 902所揭露之 一種以馬達定子線圈作為充磁線圈，不過該項技術之定位 效果會因為磁石與馬達種類不同而有較大之差異，同時也 會有充磁瞬間扭矩難以掌握之問題。又如，美國專利 U. S. Pat.

If accidentally, the foreign matter is adsorbed on the rotor. The device is inside the motor. Oh, it will cause the motor to run abnormally or even cause an unexpected situation. Therefore, in the past, the motor assembly process or the storage and transportation process that has been magnetized forever must be arranged. In order to solve the former: body: the unmagnetized magnet can be used to make the arrangement of the motor rotor process, which will help to simplify the production of the integrated motor assembly flow operation:: its assembly safety is also more Future Motor 200828734 In view of this, the current trend in the world is to improve and break through the technology in this direction. However, the method of first placing the rotor in the motor and then magnetizing the motor in the rotor positioning technology still exists. Improve the space. For example, a stator coil for a concentrated winding motor is disclosed as a magnetizing coil, and a fixed relative moving angle is defined for magnetization according to the cooperation of the magnet accommodating groove of the rotor and the stator coil, as disclosed in U.S. Patent No. 20040070361. Although this technique can be magnetized using stator windings, its disadvantages require the addition of a position sensor that detects the rotor and associated mechanisms to enable • rotor positioning. In addition, as disclosed in US Pat. No. 5, 424, 902, a motor stator coil is used as a magnetizing coil, but the positioning effect of the technology may vary greatly depending on the type of magnet and the motor. At the same time, there is also the problem that it is difficult to grasp the moment of magnetization. For example, the motor stator coil is used as a magnetizing coil, and the magnet on the rotor is an anisotropic magnet, so that the rotor is not magnetized when the magnet is magnetized, as disclosed in US Pat. No. 6,084,496. The difference in inductance from the magnetic circuit generates torque and affects the magnetization effect. Although this method has its advantages, the high cost of the anisotropic magnet increases the cost of the technology. In summary, there is a need for a permanent magnet motor rotor magnetization positioning method and apparatus to solve the problems associated with conventional techniques. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method and a device for magnetizing and positioning a permanent magnet motor rotor, which is a stator winding coil of a built-in permanent magnet motor as a vibration coil of the private road of 200828734.

The magnetic shirt is twisted and twisted to achieve the magnetization positioning. The purpose of the invention is again. And the device is magnetized and positioned by a permanent magnet motor rotor. The winding coil of the rotor and the stator is a vibrating cover coil, and the judgment mechanism is adjusted to obtain the electrical signal generated as a positioning. Mass production J.

The sub-magnetization positioning method comprises the following steps: making a stator of a motor a coil as a magnetization Positioning the inductance of the circuit; adjusting the rotor in the motor to a specific position; adjusting the magnetization positioning circuit to cause the magnetization positioning circuit to resonate; when the stator coil of the motor generates resonance, converting the resonance frequency signal to a reference voltage signal As a reference for positioning determination; and performing a mass production process according to the reference voltage signal. Preferably, the mass production process further comprises the following steps: providing a plurality of rotors to be magnetized a magnetism to be magnetized is respectively disposed in a motor body, the motor body has a stator coil; and a motor body including the rotor to be magnetized is connected to the magnetization positioning circuit to make the stator coil in the motor body The inductance of the magnetization positioning circuit; converting the oscillation signal outputted by the magnetization positioning circuit into a reference electrical calendar signal capable of determining whether the stator coil and the rotor magnet are aligned; and then adjusting the position of the magnet to be magnetized according to the reference voltage signal The reference voltage signal converted by the magnetization positioning circuit is brought to a minimum or a zero value; after the rotor magnet is aligned with the stator coil, the magnet to be magnetized can be magnetized. The present invention further provides a permanent magnet motor rotor magnetizing positioning device, which comprises: a magnetizing positioning circuit, a position adjusting device and a magnetizing power source. The magnetization positioning circuit comprises: an oscillation scanning circuit, a phase resonance adjustment circuit and a voltage signal conversion circuit. The oscillating scanning circuit is connected to the stator coil on a motor body and simultaneously uses the stator coil as the oscillating disk inductance of the oscillating cover scanning circuit. The phase resonance adjusting circuit is connected to the oscillating scanning circuit, and when the magnetizing magnet is aligned with the stator coil manually during initial magnetization positioning, the oscillating scanning circuit is adjusted to generate a resonance state. The voltage signal conversion circuit is connected to a phase resonance adjustment circuit, and the voltage signal conversion circuit can convert the output signal of the oscillation scanning circuit into a reference voltage signal which can be used to determine whether the rotor magnet and the stator coil are aligned. The position adjusting device is connected to a rotor of the motor body, and the position adjusting device can adjust the position of the rotor to change the magnitude of the signal outputted by the voltage signal conversion circuit, and the rotor has a plurality of magnets and magnet slots. The structural design. The magnetizing power source is coupled to the stator coil of the motor body to provide energy to the stator coil to magnetize the rotor. [Embodiment] In order to enable the reviewing committee to have a further understanding and understanding of the features, objects and functions of the present invention, the following is a detailed description of the relevant details of the device of the present invention and the concept of the design, so that the reviewing committee The features of the present invention can be understood, and the detailed description is as follows: Please refer to the circle 1, which is a schematic cross-sectional view of the built-in permanent magnet motor. The motor body 10 of the permanent magnet motor 1 has an accommodating space therein, and a stator 11 is disposed around the accommodating space, and the winding 11 is provided on the stator 11. In the central area of the accommodating space, there is a rotor 12 which is made of a silicon steel sheet material, and a magnet groove 120 is formed in the rotor 12 to provide a magnet 121 to be magnetized. The basic principle of the present invention is directed to a built-in permanent magnet motor. When the rotor 12 is formed into a magnet slot 120 by machining, the magnetoresistance is different with respect to the position of the stator coil, and if the rotor 12 is driven to rotate at a small angle, Measuring the inductance of the sub-wound coil 110 will result in a difference in inductance at different angles relative to the stator winding coil 110 due to the difference in magnetoresistance of the rotor 12. 200828734 . Therefore, if the stator winding coil 110 is connected to a magnetization positioning circuit (not shown) and rotates at a small angle of the rotor, the magnetization positioning circuit will have different oscillation inductances due to different rotor positions. And generating different oscillating signals, and the difference signal can be used as the determination of whether the rotor magnet and the stator coil are positive or not; wherein the inductance of the magnetizing positioning circuit is based on the stator winding coil 110 of the motor, and as an oscillation Coil. At the beginning of the magnetization positioning, after the magnet 121 of the rotor 12 is aligned with the winding coil 110 of the positive stator, the resonance frequency of the magnetization positioning circuit is adjusted to make the oscillation® scanning circuit reach a resonance state (only in the first setting and Adjustments must be made when adjusting the parameters of the magnetization positioning circuit). Thereafter, the positioning scan is repeated before the magnetization of the subsequent motor according to the state, as long as the magnet 121 of the rotor 12 deviates from the angular position of the stator winding coil 110, since the rotor magnet 121 is not located in the stator winding coil 110. The difference in magnetoresistance causes the inductance of the stator winding coil 110 to be different. 5 causes the magnetization positioning circuit to oscillate away from the resonance frequency, and the oscillation signal generated at this time is oscillated by the voltage signal converter of the analog circuit. Signal peak amplitude signal difference • Converted to a voltage signal, and the deviation angle of the position of the rotor magnet 121 from the position of the stator winding line 110 is expressed in a voltage signal pattern, and thus the change of the voltage signal can easily determine the rotor and Whether the stator coil to be magnetized is aligned, and then adjusted to the optimal position of magnetization.

Finally, step 23 is performed when the stator winding coils 40, 41, 42 of the motor resonate, and the resonant frequency 10 signal is converted into a reference voltage signal as a reference for positioning. As shown in FIG. 5A, the reference voltage signal, in this embodiment, is when the resonant oscillation waveform 90 is generated, the voltage signal conversion circuit 6 converts the signal of the resonance frequency into the reference voltage signal and is voltmeter 7 shows the reading value, at which time the reading value of the McCaw voltage signal is the smallest. The reference voltage signal can be used as a basis for judging whether the rotor and stator coils are aligned. Next, the rotor 43 can be fixed to perform a magnetizing operation. Please refer to FIG. 3, which is a schematic diagram of another preferred embodiment of the method for magnetizing a permanent magnet motor rotor magnetization. In the foregoing process, when the position of the magnet to be magnetized is adjusted so that the reference voltage signal converted and outputted by the magnetizing positioning circuit reaches a minimum or a zero value, step 24 can be performed according to the reference voltage signal to perform automatic magnetization. Mass production action. Please refer to FIG. 4, which is a schematic diagram of the mass production process of the permanent magnet motor rotor magnetization positioning method of the present invention. The mass production process further includes the following steps: First, a plurality of magnets to be magnetized are provided in step 240. Each of the magnetrons to be magnetized is disposed in a motor body, and the motor body has a stator winding coil. Next, in step 241, the motor body including the rotor to be magnetized is connected to the magnetization positioning circuit 12 200828734 . so that the stator coil in the motor body becomes the inductance of the magnetization positioning circuit. Then, step 242 is performed to convert the oscillating signal outputted by the magnetizing positioning circuit to a reference voltage signal exhibiting a peak value difference of the oscillating signal amplitude, and the reference voltage signal is used as a basis for determining whether the rotor magnet and the stator coil are aligned or not. Referring to Figure 5B, the figure is a schematic diagram showing the deviation of the rotor magnet from the stator winding coil. It can be seen from the figure that if the rotor 43 deviates from the magnetization position of the stator winding coils 40, 41, 42, the rotor magnetism 10 stones 430 to 433 do not have the difference in magnetoresistance between the stator winding coils 40, 41, 42. The inductance of the stator winding coils 40, 41, 42 is different, which causes the magnetizing positioning circuit 5 to deviate from the resonance frequency and generate a signal oscillation phenomenon, and the amplitude difference peak is larger than the oscillation waveform 91, and the oscillation signal at this time Then, the voltage signal conversion circuit 6 converts the voltage signal into a voltage signal, and the voltmeter 7 displays the reading value, and thus the change of the voltage reading value can easily determine whether the rotor magnet and the stator coil are aligned, and the associated one can determine the optimum. Magnetization position. Returning to FIG. 4, the position of the to-be-magnetized rotor is adjusted by step 243 and then according to the output reference voltage signal of step 242, so that the reference voltage signal output by the magnetization positioning circuit reaches a minimum or zero amplitude difference. Then, it can be determined that the rotor magnet and the stator coil are aligned with each other. Finally, step 244 is performed to fix the rotor position and magnetize the magnet to be magnetized after the position is positioned. Please read the picture of Figure 5C. This figure is the configuration diagram of the rotor magnetization wiring. At this time, the wires of the stator winding coils 40, 41, and 42 are connected to a magnetization power source, and the stator winding coils 40, 41, and 42 are magnetized to magnetize the magnets on the rotor 3. In this embodiment, In the example, the U/V two phases of the three phases of the stator are connected in parallel, and the W phase is connected to the magnetizing power 13 200828734, and the two poles of the source can be magnetized on the line. The magnetizing power source can be a high voltage oil capacitor charging power source. After the magnetization is completed, 240 to 244 are repeated repeatedly to perform an automated mass production operation. Refer to FIG. 6A, which is a schematic diagram of a preferred embodiment of a permanent magnet motor rotor magnetization positioning device of the present invention. The permanent magnet motor rotor magnetizing and positioning device 8 has a magnetizing positioning circuit 80, a magnetizing controller 84, a position adjusting device 85, and a magnetizing power source 81. A switch 82 is coupled to the magnetization positioning circuit 80 and the magnetization source 81. The switching on/off 82 can selectively switch to connect the stator winding coil contact of the magnetizing positioning circuit 80 to the stator winding coil 30, 31 of the motor to be magnetized or the magnetizing power source 81 and the magnet to be magnetized The stator winding coils 30, 31 are connected. The magnetizing power source 81 can supply energy to the stator winding coils 30, 31 to magnetize the rotor 33. The magnetizing power source 81 can be a high voltage oil capacitor charging power source. The magnetization controller 84 can provide control and judgment functions. The position adjusting device 85 is coupled to the motor rotor 33 to rotate the rotor * 33 to control the position of the rotor 33. The position adjusting device 85 is further connected to a position adjusting device driver 83, and the position adjusting device driver 83 can control the action of the position adjusting device 85 according to the signal of the magnetizing controller 84. In the present embodiment, the position adjustment device 85 provides a microstepping to a drive mechanism such as a microstepping motor. The position adjusting device 85 provides a brake fixing force during magnetization to fix the rotor so that the rotor is not biased by the influence of the magnetization during magnetization.

The magnetization positioning circuit 80 further includes a vibration scanning circuit 801, a resonance phase adjustment circuit 802, and a voltage signal conversion circuit 803. The actual circuit of the oscillation scanning circuit 801, the resonance phase adjustment circuit 802, and the voltage signal conversion circuit 803 As shown in Figure 6C. The oscillation scanning circuit 801 is connected to the stator winding coils 30, 31 on a motor body, and uses the stator coil as an oscillating coil of the oscillation scanning circuit. The oscillating scanning circuit 801 is connected to the stator coil 93 of the motor by a stator winding coil connection point 92. The connection method can be referred to as shown in Fig. 5A. The resonance phase adjustment circuit 802 can change the oscillation frequency of the oscillation scanning circuit to achieve a resonance state by an adjustment operation. This adjustment operation is to adjust the resistance value of one of the resonance phase adjustment resistors 94 on the resonance phase adjustment circuit 802 to cause the stator winding coil 93 to resonate. The voltage signal conversion circuit 803 is connected to the resonance phase adjustment circuit 802. The voltage signal conversion circuit 803 can convert the oscillation signal output of the oscillation scan circuit 801 into a discriminating voltage signal indicating a peak amplitude difference of the oscillation signal. The magnetization controller 84 is passed to the voltage signal detection point 95. The magnetizing controller 84 can signal the driver to control the position adjusting device to adjust the position of the rotor to maintain the reference voltage signal to zero or the lowest value according to the magnitude of the reference voltage signal. By means of the above-described method, the positional scanning of the stator coil can be used to determine whether the position of the rotor magnet is aligned with the magnetizing coil by using the differential scanning of the stator coil. Once the voltage signal value of the positioning scan detection circuit shows zero or the lowest value, it represents the rotor magnet 200828734, which is aligned with the magnetization coil, as shown in Figure 5A. At this time, the magnetizing power source charges the magnet on the rotor by switching the magnetizing controller to control the switch.
