誘導電動機のL型等価回路から導かれる電流の式より、始動電流の大きさを概算してみましょう。回転子が十分加速した時（s=0.05）と、始動時（s=1）を比較しています。 始動時に通ずる大電流が電源系統に影響を及ぼさないよう、様々な始動法が存在しています⚡️
The image is an educational diagram explaining the calculation of the starting current in an induction motor's L-type equivalent circuit. It compares the current when the rotor is sufficiently accelerated (s=0.05) versus at start-up (s=1). The diagram includes mathematical formulas for current (I) under both conditions, showing the significant difference in current magnitude at start-up. The text in the image is in Japanese, discussing the impact of the large start-up current on the power system and mentioning various start-up methods to mitigate this effect. The post is from Nori⚡️電気エンジニア (@nori15747971), emphasizing the importance of understanding these calculations for electrical engineering applications.
