University electrician! Under the condition of constant power supply voltage, if the triangle connection of the motor is wrongly connected into a star connection, or vice versa, what are the consequences?

If the triangle is wrongly connected into a star, the power will drop and the rated power will not be reached. However, if the star is connected into a triangle, the power will increase, but the motor will be burnt out! In short, when the star is connected, the voltage of each phase coil is 220 V, but when the triangle is connected, it is 380 v. the voltage is different, so the current is different!

If the three-phase asynchronous motor with triangle connection can work normally with star connection, what's wrong? Thank you

It can work under light load, if the voltage is constant, the power is about 1 / 3 of the original

Generally speaking, the AC voltage of 220 V or 380 V refers to its effective value?

Is the effective average

Is the voltage of 220 V and 380 V used in daily life DC or AC

In China, both 220 V and 380 V are AC 50 to 60 Hz
