[0025] The exemplary embodiments of this application are described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the application are shown. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.
[0026] Based on this, the embodiments of the application provide a method for adjusting the angle of a resolver in a starting generator, as shown in the figure, which comprises the following steps: Figure 1
[0027] 101, control the starting generator to operate based on a preset rotating speed, collect a plurality of angle measurement values output by the resolver in the starting generator, and calculate a plurality of angle deviation values corresponding to the plurality of angle measurement values based on a preset angle value.
[0028] Specifically, the control starts the starter generator to operate at a preset speed, for example, 2000 revolutions per minute, to simulate actual working conditions, and then collects multiple angle measurement values output by the resolver in the starter generator, usually including ABC three items. Specifically, the starter generator can be installed on a test bench for testing, and the multiple measurement values output by the resolver can be directly read through the test bench, or a special decoding chip, for example, an AD2S1210 chip, can be used to apply an excitation signal to the primary winding of the resolver, and collect two-phase orthogonal SIN / COS signals fed back by the secondary winding of the resolver. These signals represent the angular position information of the rotor relative to the stator. Then, the collected signals are processed and converted into angle measurement values. After collecting the multiple angle measurement values, the angle measurement values are compared with the preset angle values to obtain multiple angle deviation values corresponding to the multiple angle measurement values.
[0029] In the embodiments of the application, the resolver can be accurately excited and the signals can be processed by using a special decoding chip to obtain high-precision angular position information. Compared with the traditional manual reading method of the oscilloscope, the method is more accurate and reduces the possibility of human error. The test bench can also be used to collect and process the signals output by the resolver in real time without manual intervention to complete data collection and calculation, which not only improves work efficiency but also reduces the dependence on operators. Calculating the deviation values corresponding to the multiple angle measurement values based on the preset angle values can quickly determine whether there is an angle error or a fault. If it is found that the multiple angle deviation values are inconsistent, measures can be taken immediately to adjust or repair, avoiding the process of repeated disassembly and debugging and saving a lot of time.
[0030] 102、When the multiple angle deviation values are inconsistent, the resolver stator is detected by resistance detection to obtain a detection result, and the resolver stator with an abnormal detection result is replaced.
[0031] Specifically, when the calculated multiple angle deviation values are inconsistent, that is, each angle deviation value is inconsistent, it indicates that the resolver or its related components may have a fault or be improperly installed, and the starter generator needs to be disassembled for further inspection and repair. Then, the electrical characteristics of the resolver stator are checked in detail, especially by measuring the resistance value to determine whether there is an electrical fault. If the resistance detection result shows that the resolver stator is abnormal, for example, the measured resistance value is not within the expected range, the resolver stator with the problem needs to be replaced.
[0032] In the embodiments of the present application, by judging the consistency of multiple angle deviation values, potential problems in the starter generator can be quickly identified, which is more accurate than traditional manual debugging and can quickly locate the specific fault point; when the deviation values are found to be inconsistent, it can be efficiently and directly confirmed whether the resolver stator has a problem, which significantly improves the fault troubleshooting efficiency compared to repeatedly disassembling and adjusting blindly; through detailed resistance detection, the state of the resolver stator can be accurately judged, and defective components can be replaced in time; a standardized operation process is established, which not only improves work efficiency, but also ensures the consistency and standardization of each operation.
[0033] 103、When the multiple angle deviation values are consistent, the electrical angle value of the starter generator is obtained, the electrical angle value is converted into the mechanical adjustment angle of the resolver according to a preset angle conversion formula, and the resolver stator is angle-adjusted according to the mechanical adjustment angle.
[0034] Specifically, when the multiple angle deviation values are consistent, it is confirmed that the multiple angle signals output by the resolver are not abnormal, indicating that the current state of the starter generator is normal, and the electrical angle value of the starter generator is recorded. Then, the starter generator is disassembled, the resolver stator is stably installed to ensure that its position will not change due to external factors, and then the electrical angle value is converted into the mechanical adjustment angle actually required for adjustment of the resolver stator based on the preset angle conversion formula. Finally, the angle position of the resolver stator is accurately adjusted according to the calculated mechanical adjustment angle to meet the accuracy requirement specified in the operation manual.
[0035] In the embodiments of the present application, by recording the electrical angle value of the starter generator and converting it into the mechanical adjustment angle of the resolver stator using the preset angle conversion formula, very accurate angle adjustment can be achieved. After confirming that the multiple angle deviation values are consistent, the electrical angle value is directly read and subsequent operations are performed, avoiding the process of repeated disassembly and debugging. The one-time angle adjustment method significantly improves work efficiency and saves a lot of time. Using the preset angle conversion formula for automatic angle calculation and adjustment reduces the dependence on the experience and judgment of technicians, reduces the risk of human error, and improves the stability and reliability of the entire system. The whole process is more efficient, the occupancy time of the test bench is reduced, more components can be tested and maintained in the same time, thereby improving the overall equipment utilization.
[0036] The application provides an angle adjustment method for a resolver in a starter generator, which can quickly determine whether the resolver is working normally by measuring multiple angle measurement values output by the resolver and calculating corresponding multiple angle deviation values, improves the accuracy and reliability of angle measurement, reduces the dependence on the experience of technicians, makes the whole adjustment process more standardized and controllable, and improves work efficiency and consistency; for the inconsistent deviation values, the resolver stator is directly checked for faults instead of being repeatedly disassembled and manually adjusted, thereby reducing unnecessary disassembly times, reducing the occupancy time of a test bench, saving time and human resources, and improving the overall equipment utilization.
[0037] The application provides another angle adjustment method for a resolver in a starter generator, as shown in the formula (1), which comprises the following steps. Figure 2
[0038] 201, install the starter generator on a test bench, control the starter generator to operate based on a preset rotating speed, and collect multiple angle measurement values output by the resolver in the starter generator by using the test bench or a resolver decoding chip.
[0039] In the application, for the collection of the multiple angle measurement values output by the resolver, in one case, the starter generator to be adjusted can be directly installed on a K938 test bench, the K938 test bench has larger power and higher rotating speed compared with other test benches, and functions cover the test and verification of all model IDG (integrated drive generator), CSD (constant speed) and APU (auxiliary power unit) generators of airbus A380 and Boeing 787, then the rotating speed of the starter generator is increased to 2000 revolutions per minute, and then data reading is performed; in another case, an excitation signal is applied to the resolver decoding chip, and then data reading is performed.
[0040] 202, collect the multiple angle measurement values output by the resolver in the starter generator, and calculate multiple angle deviation values corresponding to the multiple angle measurement values based on a preset angle value.
[0041] In the embodiment, a preset angle value is set according to a manual or design requirement, the preset angle value is determined based on an angle position expected when the starter generator works normally, the multiple angle deviation values are calculated by comparing the difference between the actually collected angle measurement values and the preset angle value, and then the consistency of the multiple angle deviation values is judged.
[0042] Specifically, an excitation signal is applied to the primary winding by using the resolver decoding chip, and a differential signal generated by the secondary winding is collected, acceleration information is determined based on the differential signal, and the multiple angle measurement values are obtained by double-integrating the acceleration information.
[0043] In the embodiment of the present application, the resolver decoding chip is preferably an AD2S1210 chip, an excitation signal of 7Vrms / 10kHz is applied to the primary winding of the resolver through the AD2S1210 chip, and then the acceleration information is obtained according to the signal difference output by the secondary winding, and the speed information is obtained after integration, and the multi-angle measurement value is obtained after integration of the speed information.
[0044] The resolver includes a rotor, a primary winding and two secondary windings, wherein the two secondary windings are arranged perpendicularly to form a phase difference of 90°.
[0045] In the embodiment of the present application, as shown in Figure 3 The primary winding has two terminals, marked as R1 and R2 respectively, and the primary winding is an excitation winding, usually applying an alternating voltage signal; the secondary winding has four terminals, marked as S1, S2, S3 and S4 respectively, wherein S1 and S3 and S2 and S4 respectively constitute two independent secondary windings, the secondary winding receives the electromagnetic induction signal from the primary winding, and generates a corresponding output voltage according to the position of the rotor, the two secondary windings are perpendicular to each other in mechanical structure, and the phase difference is 90 degrees to provide orthogonal output signals; the circle in the figure is the rotor, which is the core rotating component of the resolver, usually made of magnetic conductive material, and rotates with the rotation of the mechanical shaft, for coupling the rotating magnetic field generated by the primary winding into the secondary winding; specifically, when the alternating voltage is applied to the primary winding, a rotating magnetic field will be generated around the rotor, considering the rotation of the rotor, the magnetic field will be coupled into the two secondary windings, thereby inducing a voltage in the secondary winding, and since the phase difference of the two secondary windings in mechanical structure is 90 degrees, the phase difference of the voltage signals output by S1-S3 and S2-S4 is also 90 degrees.
[0046] Specifically, after obtaining the multi-angle measurement value, it is necessary to calculate the multi-angle error value, and when the multi-angle error value is less than the error threshold, it is determined that the multi-angle measurement value meets the preset requirements.
[0047] In the embodiment of the present application, before determining the consistency of the multi-angle deviation value, it is necessary to determine that the multi-angle measurement value meets the preset requirements, and specifically, the secondary winding output signal and the corresponding error need to be calculated, and the specific process is as follows:
[0048] First, the output voltages of the two secondary windings are obtained, respectively
[0049] S3-S1=E0sinwt x sinθ,
[0050] S2-S4=E0sinwt x cosθ,
[0051] Wherein, θ is the shaft angle, sinwt is the primary winding excitation frequency, E0 is the rotor excitation amplitude;
[0052] introducing For measurement error, get:
[0053]
[0054] Further calculate the difference between the two values:
[0055]
[0056] Since the excitation frequency signal is known, the excitation signal is demodulated to obtain:
[0057]
[0058] Further equivalent to
[0059]
[0060] When The value is small, Approximately equal to The value obtained is the difference between the rotor angle error and the resolver output. By verifying the relationship between θ and Verify the angle value and the angle error, and determine that the error value is less than 1 degree, which meets the determination requirements.
[0061] 203、When the multiple angle deviation values are inconsistent, the resolver stator is detected for resistance to obtain a detection result.
[0062] Specifically, the fixing screws of the resolver stator are removed, and the detection resistance value of the resolver stator is collected. The detection resistance value is compared with the preset resistance value range.
[0063] In the embodiment of the application, when the multiple angle deviation values are inconsistent, it indicates that the resolver stator is installed incorrectly or the resolver stator has a fault, so the starting generator needs to be removed. Specifically, 6 fixing screws of the resolver stator are removed. Then, the coils of the resolver stator are connected through the pins in the electrical plug. The connected pins are specifically marked as 7-12 pins. The detection resistance value between the adjacent two pins is collected and compared with the preset resistance value range. The resistance value of the 7th and 8th pins must be between 26-28Ω, the resistance value of the 9th and 10th pins and the 11th and 12th pins must be between 31-34Ω, and different operations are performed according to the final detection result.
[0064] 204、Replace the resolver stator with an abnormal detection result.
[0065] Specifically, when the detected resistance value is outside the preset resistance value range, the detection result of the resolver stator is determined to be abnormal. The resolver stator is replaced, the starter generator is reassembled, and it is reinstalled on the test bench.
[0066] In this embodiment of the application, when the detection resistance value of the resolver stator is not within the preset resistance value range, that is, the resistance values of pins 7 and 8 are not within the range of 26-28Ω, and the resistance values of pins 9 and 10, and pins 11 and 12 are not within the range of 31-34Ω, it can be determined that there is a problem with the resolver stator, and therefore it needs to be replaced as required.
[0067] 205. Reassemble the resolver stator that has a normal test result.
[0068] In this embodiment of the application, whether it is a resolver stator with normal test results or a replaced resolver stator, the generator needs to be reassembled and started. Specifically, when installing the resolver stator, the six screws that fix the resolver stator need to be tightened step by step, and the torque should be tightened diagonally as required. First, a torque of 3-4 pounds-inches is completed, and then a torque of 5-6 pounds-inches is completed, ensuring that the torque value does not exceed the standard of 5-6 pounds-inches.
[0069] 206. Perform the determination of multiple angle deviation values again.
[0070] Specifically, the starter generator is controlled to run at a preset speed, and multiple angle measurement values output by the resolver in the starter generator are re-acquired, and multiple angle deviation values corresponding to the multiple angle measurement values are calculated; when the multiple angle deviation values are inconsistent, the resolver stator is re-wound based on preset process requirements.
[0071] In this embodiment of the application, after the resolver stator is installed, it is necessary to re-determine multiple angle deviation values. If multiple angle deviation values are still inconsistent, it indicates that the lead end was judged incorrectly during coil winding or that there is a short circuit between turns in the coil. The winding of the resolver stator needs to be completed again as required.
[0072] 207. When multiple angle deviation values are consistent, the electrical angle value is converted into a mechanical adjustment angle based on a preset angle conversion formula, and the angle of the resolver stator is adjusted according to the mechanical adjustment angle.
[0073] Among them, such as Figure 4 As shown, the starter generator includes a starter power supply unit and a system control unit. The system control unit includes an excitation power supply and an inverter. The starter power supply unit is connected to the excitation power supply and the inverter respectively. The excitation power supply is connected to the stator of the starter generator's excitation generator, and the inverter is connected to the stator of the starter generator's main generator. The inverter is also used to receive the signal output by the resolver and to supply power to the resolver.
[0074] Specifically, the preset angle conversion formula is that the electrical angle value of the starting generator is equal to the product of the mechanical adjustment angle of the resolver and the number of pole pairs of the starting generator.
[0075] In the embodiment of the present application, after the starting generator is connected in the structure of Figure 4 slowly rotating the rotor of the motor, observing the angle value calculated by the resolver, and manually rotating the shaft of the starting generator, the actual mechanical angle of 360 degrees is measured, the resolver output is 0-360 degrees twice, the electrical angle is calculated as 720 degrees, the number of pole pairs is 2, and the basic rule of angle calculation is formed, that is, when rotating clockwise, the angle decreases, when rotating counterclockwise, the angle increases, and the actual deviation angle changes by 2 degrees for every rotation of the resolver, thus forming the preset angle conversion formula:
[0076] electrical angle = number of pole pairs x mechanical angle.
[0077] 208, reinstall the resolver stator and fix it.
[0078] Specifically, to ensure that the resolver stator and the resolver rotor are in the same plane and do not cause inaccurate angle measurement due to the deflection angle between the resolver stator plane and the resolver rotor plane, the resolver stator is reinstalled to the resolver, the fastening screws are controlled step by step based on the preset torque requirement according to the diagonal fastening order.
[0079] In the embodiment of the present application, according to the angle calculation rule, the fixing screws of the resolver stator are removed, a special designed tool is used to tighten the resolver stator of the starting generator with three claws, and then the resolver stator is rotated and adjusted according to the calculated digital value, after the resolver stator is reinstalled, the six screws of the resolver stator are installed again according to step 205.
