A beginner seeking advice on how to connect a pump? ? Thank you
Thread Content
Dear teachers, I’m a beginner and would like some advice on how to connect this pump. As shown in the diagram, there are 6 poles. My power supply is 220V, and from the nameplate I can see that the pump’s power rating is 1.1 kilowatts. Use a star connection? So where do my L and N connect? Thank you
You can only add a capacitor for this; just search on Baidu
If you have 220-volt single-phase power there, buy an inverter to convert it to three-phase
Teacher, if I use 380V here, does it mean that only 3 live wires are needed, and no neutral wire is required?

Check the voltage specified on the motor for a delta connection, and also the voltage for a star connection; connect it accordingly
It depends on the requirements of your company – is protective grounding or neutral connection necessary?
What is the principle behind using an inverter to convert 220 volts into three-phase electricity?
On-site 3-phase 220V power supply? Do you have a photo of the motor nameplate?
You’ve never worked as an electrician; the most basic thing to know is that it’s three-phase power, L1, L2, L3. Only with three-phase power can star-delta and delta connections be used
