Advantages and Disadvantages of Y-connection and △-Connection of Three-phase Asynchronous Motor
Main and tail connection: three windings, then three - phase power supply. The winding schematic is triangular;
Y connection: three windings are connected together as the neutral point, and three tails are connected with three-phase power.
Air current connection has the advantage of high output power, high starting torque, and high starting current.
The Y connection has the advantage of low starting current, but low power and torque.
Output power of the same motor: current is 3 times of current Y.
