情境
Designing a motor control circuit for starting a three-phase induction motor directly from the line with overload protection.
這張圖裡有什麼
看懂背後的決策。
01
Three-phase power routing through main contacts and overload relay
02
Control circuit with start/stop pushbuttons and self-holding auxiliary contact
03
Overload protection using thermal relay with NC contact in series with coil
When a motor requires full voltage starting and the power system can handle the inrush current.
