Abstract
The utility model discloses a high power permanent synchronous generator with six-phase double Y-shaped windings shifted through 30 degrees, which solves the problem of being inconvenient in wire connecting caused by the fact that the dimension of a motor is too large because a wire outgoing method of the existing six-phase motor windings is that a wire goes out from one end of a machine base. The high power permanent synchronous generator comprises a machine base (1) and a stator (2). Main wire connecting boxes are fixedly arranged on the stator (2), and a three-phase power supply electric conducting ring U, a three-phase power supply electric conducting ring V, a three-phase power supply electric conducting ring W and a three-phase power supply neutral ring N are arranged on electric conducting ring supporting sticks at two ends of the stator respectively. The six-phase double Y-shaped windings shifted through 30 degrees are two sets of independent three-phase Y-shaped windings, star points of a tail end of each phase of winding are sealed inside, the six-phase windings are divided into two sets, three electric conducting rings are arranged at two ends of the stator (2) respectively, six busbars are used for leading out head ends of three phases of each set from two ends of the machine base (1) respectively, and two identical main wire connecting boxes are assembled at two ends of the machine base respectively. The two sets of coils supply power independently, dimension of the motor is greatly reduced, and a wire connecting space is saved.
