拆解電子定時器，看看內部都有什麼元件？它如何工作的？漲知識了 #我愛電器維修

Today we dismantle an electronic timer This kind of timer is in the previous electric pressure cooker There are more microwave ovens used Today we take it apart Take a look at its internals and how it works This is the front two screws two behind Let's remove the two front ones first. Okay, after we open this cover See there are a lot of gears in this It seems that the workmanship is quite precise. Then we remove the two screws at the back The part with the iron shell on the back It's a small motor, let's take a look This is the bearing of the motor Look at how gently it can turn Then this is the front It is equivalent to the reduction gear here. timer gear Let's put this motor first and then buckle it up first Let's take a look at this after buckle up There are three leads on the timer Three Wiring Sheets The one on the far right is the input power of 220 it is a public port These two are connected to the motor Then this is also connected to the load when the stabilizer is not on It is by default that the two corners are separated When we set the phonator we set it after 20 Then the two corners are connected. When it is turned on, then the load will be powered Then the motor also has power at the same time. The motor will start to rotate when there is electricity Then drive the gear and he also turns when that gap this turns to this black after this He disconnected the power after power off Then the motor dies Then there is no electricity In this way a control can be achieved The role of this silver horn electrification After understanding how it works while we are wiring These three wires will no longer be connected incorrectly. its inside The internal structure does not look particularly complicated. is the main motor and gear
