|---|---|---|---|
| X | 110.946 | 110.688 | -0.14% |
| Y | 110.134 | 109.998 | -0.13% |
| Z | 110.138 | 109.970 | -0.25% |
5. Hluav Taws Xob Cov Nqi
5.1 Cov Khoom Siv Hluav Taws Xob
Winding kev tawm tsam tau ntsuas ntawm 22 degree thiab extrapolated rau txheem kub (rooj 4).
Rooj 4: Coil Kuj
| Tus ncej | R @ 23 degree (ω) | R @ 20 degree (ω) | R @ 85 degree (ω) |
|---|---|---|---|
| X | 5.770 | 5.717 | 7.427 |
| Y | 1.210 | 1.199 | 1.557 |
| Z | 0.820 | 0.813 | 1.055 |
5.2 Cov Txheej Txheem Kev Coj Ua Haujlwm
Inductive Referance (Z) thiab Inductance (LS) tau luam tawm los ntawm 20Hz-1kHz. Cov kev ntsuas tseem ceeb muaj xws li:
X-axis (Rooj 5):
- LS: 230.187Mh (Min) txog 233.043mh (max)
- Z: 29.88ω (Min) txog 1.448Kω (Max)
Y-axis (rooj 7):
- LS: 24.5819MH (Min) rau 24.7993mh (max)
- Z: 3.285ω (Min) txog 154.495ω (Max)
Z-axis (rooj 9):
- LS: 10.9104mh (min) txog 10.9646mhmh (max)
- Z: 1.593ω (Min) txog 68.574ω (Max)
Tag nrho cov zaus cheb cov ntaub ntawv muab rau hauv cov rooj 6, 8, 10.
6. Xaus
Cov txheej txheem qhia ua raws li cov lus sib nqus uas tau tso zis tawm ({{{{}}. 25% sib xyaw ua ke, thiab cov khoom siv hluav taws xob. Tag nrho cov kev kuaj xyuas cov kev sim ua kom haum nrog cov kev xav tau, lees paub kev npaj siab rau kev xa tawm. Daim ntawv tshaj tawm no yog kev ua tiav kev ua tau zoo rau cov khoom siv tau.
