The calculation is wrong. The phase/winding voltage in a Wye connected motor is (Line Voltage)/sqrt of 3 440/sqrt of 3 = 254.3 Volts Therefore, each winding is subjected to a Voltage of 254.3 volts, when it is supposed to be only connected to 220v. Is this possible? Yes but it will greatly affect the motor's lifetime and health and it will also run at a higher temperature due to more current running in the windings compared to its supposed rated operating current. Dont take this the wrong way tho Sir Lecky Jake, I really find your videos very helpful and informational, saludo!!!

It is not safe bro.it will burn the winding eventually. because in delta connection, phase current= line current/√3. But when you connect it in wye then, phase current=line current, which will be higher than the delta connection. So, winding will be overheated due to high phase current and possibly burn. By the way voltage on each phase will be 255v in wye connection and it is designed for 220v. So i believe, you do know what will happen then.

I dont how he converted it into 440V. But I think you also got the wrong idea because the Voltage @ Delta in Line to Line = Phase and The Voltage @ Wye in Phase = Line to Line /sqrt of (3). Therefore the current @ wye will become smaller since 220/sqrt(3)=127.

The line current will be less, winding current the same (check the calculation with resistors). Only problem is the coils are getting 250+ volts when rated for 220 volts. If the motor is not designed well, the higher voltage will cause magnetic saturation.

Still a bit higher than 220V rated voltage, it will affect the motor lifespan in the long run. I am sure that Jake is fully aware including all mathematical calculation.
