#工業大小事 ── ✦ AC交流馬達✦ ── 《 常見3種介紹 》 🤓打開手持砂輪機，在焊接工作中十分常見，但是打開後發現砂輪機越轉越慢就不太樂見了，往往旁邊的老師傅都會跟你說，這碳刷該換了。 - 然後你心想，為什麼家裡電風扇用了十幾年也沒換過碳刷?而手持砂輪機用沒一兩年卻就要更換了，其實，這一切都與它們肚子裡藏著不同類型的「馬達心臟」有關。 - 📌#什麼是AC馬達 ▸試想一下，當我們按下開關，家用的交流電（AC, Alternating Current），流進馬達機構使其旋轉，這類馬達便統稱為「交流馬達」。而在工業與生活中，我們最常遇見以下三種： - 📌#感應馬達 Induction Motor ▸感應馬達最特別的地方在於，轉子的電源、是利用旋轉磁場感應出來的，轉子上的感應電流產生了自己的磁場，與定子的旋轉磁場相互作用，導致轉子被推著轉動。轉子的速度永遠會慢於旋轉磁場的速度所以產生轉差 (Slip)，這也是為什麼它又叫「異步馬達」，感應馬達的構造非常簡單耐用，所以經常利用在許多家用電器之上，傳統電風扇就是最好的範例。 - 📌#同步馬達 Synchronous Motor ▸如
