The difference between triangle start and star start of three phase asynchronous motor?
The starting of three-phase asynchronous motor is full voltage starting when it is △ or Y-shaped according to the connection method indicated on the nameplate. If the connection method indicated on the nameplate is △ and Y-shaped connection method is adopted, it is step-down starting, and the starting current is 1 / 3 of the original connection method. If the connection method indicated on the nameplate is Y-shaped and △ connection method is adopted, it is not suitable for three-phase 380V load, but only suitable for three-phase 220V load

A bulb with rated voltage of 8V and rated power of 16W is connected with a bulb with coil resistance R of 0.5 Ω After the DC motor is connected in parallel with the power supply, the bulb just lights normally, and the total current is calculated ① U motor = u bulb = 8V = u external circuit ﹥ u internal circuit = E-U external circuit = 4V ﹥ total current = 4V ﹥ 0.5eu = 8A ② R outer = 4 × 0.5 △ 4 + 0.5 = 4 / 9 total current = E / (4 / 9 + 0.5) = an extra large fraction Why are the numbers calculated different? Why is the second method wrong?
