Abstract
The invention relates to an alternating current (AC) motor wave winding and a transpositional connection method thereof, and aims at a low-voltage high-current wave winding AC motor. The two-layer single-turn wave winding coil of the AC motor is replaced with a two-layer two-turn wave winding coil, and the current of each turn is half than that of the two-layer single-turn wave winding coil; and the two-turn wave winding coil has four noses capable of implementing twisting transposition. The transpositional connection method comprises the following steps: the ends a and d and the ends b and c of the noses are connected respectively; each connected phase winding forms four branches, respectively a1d1, a2d2, b1c1 and b2c2; one of the branches of a1d1 and a2d2 is connected with one of the branches of b1c1 and b2c2 in series to form a new branch; and two branches of the same phase in each phase winding are connected in series or in parallel. The AC motor wave winding has the advantages of implementing the secondary transposition of conductors in the motor winding and the uniform current distribution of the conductors connected in parallel in the coil, reducing the current-circulation loss and the temperature difference between conductors, prolonging the insulation service life and improving the output and operation efficiency of the motor. The transpositional connection method is simple in process and obvious in effect.
