If you aren't qualified to do this, please do not do it. The risk of fire and shock is real, and you don't want to hurt anyone or burn the place down. Call a qualified electrician -- that is what they do.

It's currently wired in star. Please anyone
Most 3-phase fan motors have terminals labeled U, V, and W, which correspond to the three phases. You may also find a terminal for the ground wire, which is typically marked with a ground symbol or the letter "G". Check the motor's nameplate or manual for specific details and wiring diagrams.
A 3-phase fan motor typically requires a plug that can handle the voltage and current specifications of the motor. Commonly used plugs include NEMA L15-30 for 250V and 30A, or IEC 60309 for higher voltages and currents. Ensure the plug matches the motor's requirements and the socket it will connect to.
To wire a 3-phase plug to the motor, connect each of the three phase wires from the plug to the corresponding terminals on the motor (U, V, W). Ensure that the ground wire from the plug is connected to the motor's ground terminal. Double-check all connections for security and proper insulation.
Before starting, ensure the power supply is turned off and locked out to prevent accidental energization. Use appropriate personal protective equipment (PPE) such as insulated gloves and safety glasses. Verify all connections are secure and properly insulated to avoid electrical shorts or shocks. Follow local electrical codes and standards.
After wiring, you can test the motor by briefly powering it up and observing its operation. The motor should start smoothly and run without unusual noises or vibrations. Use a multimeter to check that the voltage at the motor terminals matches the motor's rated voltage. If the motor runs in the wrong direction, you may need to swap two of the phase wires.
