220伏電機怎麼接電容？怎麼接電源線？方法簡單一看就會 #我愛電器維修

How to connect a 220 volt motor to a capacitor unexpectedly There are many people who will not be in the background I often send private messages to ask me how to connect the capacitor. Today's video to share with you Either this 3-wire motor or this uh Motors used on 5-wire or 6-wire fans In fact, the way they connect the starting capacitor all the same Let me share with you today Take this three-wire motor as an example. Let me share with you how to connect it First look, what about a three-wire motor like this? Its internal winding is like this It has two windings The two windings are connected in series there is a tap in the middle Then what about the front line and the back line There are three lines in total The coil with the smallest resistance is connected to 282 volts of alternating current The largest resistance It's the two coils connected in series. Maximum resistance He is connected to the start capacitor Let me share it with you First of all, when we pick up First you need a multimeter Let's measure his three wires It is the resistance of the two windings We first adjust the multimeter to the ohm position Then measure these three lines arbitrarily measure first this yellow red It is 39.5 ohms and then measure again Yellow purple 39.1 euros Then measure red and purple 78.6 euros These two resistances are the largest What is the maximum resistance? It's connected to the start capacitor. We put these two lines Connect it to the start capacitor After receiving it like this then we come again connected to 220 volts of alternating current see how to pick up When we first picked it up, we were still the same look for this first Run the two lines with the smallest coil resistance Let's measure this yellow line Then measure this with other connecting wires and it is 39.1 and then measure this 39.5 These two are almost the same the same time I don't know which is the running coil, what should I do? In fact, we can connect him first if we want. Connect the yellow one first Then these two lines we can pick any Feel free to connect him first After it's connected, let's power it up Let's see if the motor starts we plug it in here look at this motor Let's see it's turned, right? when to turn Let's see which direction it turns First unplug the power and let's take a look it turns like this So how to make this motor rotate forward? Actually, we can pour this line down just turn it upside down This red thread takes it down Then connect another purple wire These two wires are connected to capacitors. We can connect this line and test it again For this the resistance of the two coils is the same we can come upside down Let's take another look at the motor after it's upside down the direction of its speed Then we unplug and look again Because it's too fast Let's take a look after unplugging This is how it turns is turning forward now Connect the purple line to forward rotation Connect the red line to invert This is a way to connect the motor to the starting capacitor OK, thank you for watching the video see you next time
