Motor: 220V/380V, connected in Δ/Y configuration
Thread Content
The factory has an electric motor with a power rating of 0.37 kW. The nameplate indicates that it should be connected at 220V/380V in Δ/Y configuration. Since the factory uses a three-phase five-wire system, the three live wires connected to the motor are currently arranged in a Y configuration. Is the power output still 0.37 kW in this case? Can I increase the power by changing the motor’s connection to a Δ configuration while keeping the power supply unchanged (three live wires)?
One more thing: can Δ be connected at this time?
220V in delta connection, 380V in star connection
With the three live wires of the motor connected in a Y configuration, is the power at this point 0.37 kW? With the power supply unchanged (three live wires), changing the motor connection to delta results in a power of 0.37 kW.
I have a question: I currently have three live wires – can I use corner joining? It says on the Internet that Japan adopted it
There are 6 terminals in the motor terminal box; connect three of them together, and the other three terminals form a Y-star connection； Two connected together form a △ triangle
If you connect it in a triangular shape, 220V is required; otherwise the motor will burn out
The rated voltage of the coil is 220V; when connected in a triangular configuration, the power output increases, which will cause the motor to burn out quickly
When connected in a triangle, the power becomes three times the original value
Because the power supply is three-phase 380
