The shaft inductance value is not limited to estimating a single operating point, but can accurately and quickly estimate the inductance value of the motor at any operating point.

全球為了統一馬達能效等級,以促進競爭性的馬達市場轉型,各國實施最低能源效率標準(Minimum Energy Performance Standard, MEPS ),主要參考國際電工委員會(The International Electrotechnical Commission, IEC)馬達能效分級標準。其中變頻馬達效率規範為IEC60034-30-2,其範圍包含0.12-1,000kW,額定轉速在1-6,000RPM。馬達效率標準分為5個等級,分別為標準效率(Standard Efficiency, IE1)、優級效率(High Efficiency, IE2)、超高效率(Premium Efficiency, IE3) 、超優級效率(Super Premium Efficiency, IE4)與特超優級效率(Gold Standard Efficiency, IE5),IE5能效標準已成為未來馬達目標。In order to unify motor energy efficiency levels and promote the transformation of the competitive motor market, countries around the world implement Minimum Energy Performance Standard (MEPS), mainly referring to the International Electrotechnical Commission (The International Electrotechnical Commission, IEC) Motor energy efficiency classification standards. Among them, the efficiency specification of the variable frequency motor is IEC60034-30-2, its range includes 0.12-1,000kW, and the rated speed is 1-6,000RPM. The motor efficiency standard is divided into 5 grades, namely Standard Efficiency (IE1), Superior Efficiency (High Efficiency, IE2), Premium Efficiency (IE3), Super Premium Efficiency (IE4) ) and super-superior efficiency (Gold Standard Efficiency, IE5), IE5 energy efficiency standard has become the goal of future motors.

IEC60034-30-2馬達分級標準依照IEC61800-9-2變頻馬達系統能效規範進行測試,在IEC61800-9-2中,效率規範的範疇分別為完整驅動模組(Complete Drive Modules, CDM)及電力驅動系統(Power Drive System, PDS),前者指單一變頻器,後者為變頻器及馬達。將功率範圍為0.12 kW至1,000 kW,進行效率等級的定義,並依照馬達轉矩與轉速不同,定義八個操作點,分別對各操作點計算損失評估能效。馬達電感值會隨操作點不同而有所差異,因此在做電機的參數鑑別時,不能只針對額定點進行量測。The IEC60034-30-2 motor classification standard is tested in accordance with the IEC61800-9-2 energy efficiency specification for variable frequency motor systems. In IEC61800-9-2, the categories of efficiency specifications are Complete Drive Modules (CDM) and electric drives. System (Power Drive System, PDS), the former refers to a single inverter, the latter is an inverter and a motor. The power range is 0.12 kW to 1,000 kW, and the efficiency class is defined, and eight operating points are defined according to the different motor torque and speed, and the loss is calculated for each operating point to evaluate the energy efficiency. The motor inductance value will vary with the operating point, so when doing the parameter identification of the motor, it cannot be measured only at the rated point.

一般在選購市售馬達時,無法得知其相關的電機參數,若操作者需要此資訊,必須藉由相關規範及精確的量測設備來得知。目前,針對感應馬達的參數鑑別已有許多廣泛的研究,但針對同步馬達參數鑑別的技術及相關文獻較少。Generally, when purchasing a commercially available motor, it is impossible to know its related motor parameters. If the operator needs this information, he must obtain it through relevant specifications and accurate measuring equipment. At present, there have been many extensive studies on parameter identification of induction motors, but there are few technologies and related literatures for parameter identification of synchronous motors.

電感是影響馬達功率因數與轉矩,極為重要的參數之一,且馬達電感並非為一常數值,主要與電流大小、電機的動態響應與穩態特性息息相關,換言之,電感之大小會隨著電流大小而不同,再者,先前技術需額外之設備,且易受設備的限制(尤其當馬達輸出功率增加時,電源供應器體積不但大,且成本非常高),無法以馬達真實運轉下之操作點進行測試,因此,如何能在馬達真實運轉下,進行

In addition, the prior art requires additional equipment, and is easily limited by the equipment (especially when the output power of the motor increases, the power supply is not only large, but also very expensive), and it cannot operate under the actual operation of the motor. point to test, therefore, how can the actual operation of the motor,

This LCR meter measurement method is used by most people, but its disadvantage is that it can only measure the inductance value of the current below 10~100mA, which does not meet the normal operation conditions of the motor, and cannot obtain a complete current versus inductance curve.

First, the three-phase extended back EMF of the motor can be estimated and obtained by using the measured current and voltage, and using the q-axis inductance parameter and the stator resistance parameter. Next, a discrete time model of the motor is used to calculate the stator current value at the next sampling time. Then, define the cost function to calculate the corresponding cost function value of the inverter at the next sampling time under all possible switching states. By selecting the voltage vector with the smallest cost function value, the switching state of the next sampling time is determined to directly control the gate signal of the inverter. Compared with the traditional current hysteresis control, the proposed predictive current control can effectively improve the current tracking capability of the motor drive system.

The method can be applied to embedded permanent magnet synchronous motor and synchronous reluctance motor drive system. In order to implement the proposed predictive current control method, first, current sampling is performed before and after the switch switching in each sampling interval, respectively. Next, using a simple subtraction operation, calculate the corresponding change in stator current of the motor over the switching interval. Then, through a simple addition operation, the corresponding stator current of the motor can be predicted for all possible switching modes of the next switching.

The error between the command and the actual current, as well as the position of the motor shaft, determines the optimal inverter switching mode, eliminating the need for complicated current control loops and additional hardware circuits.

第2圖為一流程圖,用以顯示說明利用如第1圖中之本發明之馬達量測系統以進行馬達量測方法的流程步驟。如第2圖中所示之,首先,於步驟101,首先,進行參數取得動作;量測模組2將量測並取得待測馬達之參數,該待測馬達之該些參數包含電壓、電流、電阻、功率因數、轉矩、轉速與馬達極數,其中,馬達極數不需透過量測取得,其餘皆由量測結果取得;該量測模組2將該待測馬達之該些參數傳送至馬達演算法模組3,並進到步驟102。FIG. 2 is a flow chart for illustrating the flow steps of a motor measurement method using the motor measurement system of the present invention as shown in FIG. 1 . As shown in FIG. 2, firstly, in step 101, firstly, the parameter acquisition operation is performed; the measurement module 2 will measure and acquire the parameters of the motor to be tested, and the parameters of the motor to be tested include voltage, current , resistance, power factor, torque, rotational speed and the number of motor poles, among which, the number of motor poles does not need to be obtained through measurement, and the rest are obtained from the measurement results; the measurement module 2 determines these parameters of the motor to be measured Send to the motor algorithm module 3, and go to step 102.

於步驟102,進行迭代演算動作;馬達演算法模組3利用量測模組2所取得的該些參數,利用馬達演算法進行迭代,並進到步驟103。In step 102 , an iterative calculation operation is performed; the motor algorithm module 3 uses the parameters obtained by the measurement module 2 to iterate by using the motor algorithm, and proceeds to step 103 .

), and proceed to step 1023.

於步驟1023,得出電壓計算值;將步驟1022所得之電感值及電阻(

Figure 02_image035
)、電流、轉速(
Figure 02_image037
)、電流相位角,共5個參數,代入方程式得到一電壓計算值(

於步驟1024,檢驗計算電壓值(

Figure 02_image039

Figure 02_image041
);若計算電壓值(
Figure 02_image039
)不等於量測電壓值(
Figure 02_image041
),需重新假設一電流相位角,例如,將假設之電流相位角

減0.5,在此,此數值視實際施行情況而可自行變更,並回到步驟1022,開始重複步驟1022、1023、1024,直至計算電壓值(
Figure 02_image039
)與量測電壓值(
Figure 02_image041
)相符合;若計算電壓值(
Figure 02_image039
)等於量測電壓值(
Figure 02_image041
),即可確定其電壓、電流相位角與電感值,並進到步驟103。 In step 1024, check the calculated voltage value (
Figure 02_image039
) is equal to the measured voltage value (
Figure 02_image041
); if the calculated voltage value (
Figure 02_image039
) is not equal to the measured voltage value (
Figure 02_image041
), it is necessary to re-assume a current phase angle, for example, the assumed current phase angle
Figure 02_image024
Subtract 0.5, here, this value can be changed by itself depending on the actual implementation situation, and go back to step 1022, and start to repeat steps 1022, 1023, 1024 until the voltage value (
Figure 02_image039
) and the measured voltage value (
Figure 02_image041
) is consistent; if the calculated voltage value (
Figure 02_image039
) is equal to the measured voltage value (
Figure 02_image041
), its voltage, current phase angle and inductance value can be determined, and then go to step 103.
