Description

A Single-Turn Multi-Turn Continuously Wound Formed Laminated Winding

technical field

The utility model relates to the motor industry, in particular to a single-turn multi-turn continuous winding forming stacked winding.

Background technique

As the power of the motor increases or the speed increases, the current of the stator winding of the motor is larger and the number of turns is less. The traditional stator winding is a lot of single-turn coils. After the single-turn coil is embedded in the stator core, the single-turn coil The head and the tail of the adjacent single-turn coil are welded together to form a stacked winding. There are many welding heads and the process is complicated. The utility model has developed a single-turn multi-turn continuous winding forming stacked winding. high sex.

The technical scheme of the utility model is: a single-turn multi-turn continuous winding forming stacked winding, which consists of a wire head, an upper layer initial end, an upper layer conductor, an upper layer end, a secondary transition arc, a lower layer end, and a lower layer conductor , the initial end of the lower layer, the initial transition arc, the bridge and the tail of the wire; it is characterized in that: from the initial end of the upper layer, the upper conductor, the upper end, the secondary transition arc, the lower end, the lower conductor, and the lower end First, turn to the initial transition arc, complete a turn is a single turn, a single turn forms a single turn, when the total number of slots of the motor is N, the number of magnetic poles is P, the span of the three-phase winding is 2/3 pitch, and the parallel branch When the number is A, the number of slots spanned between the upper layer conductor and the lower layer conductor is 2N/3P, according to which a continuous N/3P circle is formed under one magnetic pole as a group, through the bridge, from the beginning of the lower layer to the lower conductor , the end of the lower layer, the secondary transition arc, the end of the upper layer, the upper conductor, the initial end of the lower layer, and the initial transition arc, forming a second group of continuous N/3P circles under the next magnetic pole, and then forming P/A in turn groups, P/A groups are connected through bridges according to the first group of openings, the second group of closed ports, and the third group of openings. U, V, and W three-phase windings are formed by connecting, the U-phase winding is distributed from the first slot, the V-phase winding is distributed from the 1st+120/(180 P/N) slot, and the W-phase winding is distributed from the 1st+240 /(180 P/N) Slot starting distribution.

Its working principle: a single-turn multi-turn continuous winding forming stacked winding, which can form a three-phase winding, embedded in the stator core, can cut the magnetic force line in the generator to generate a three-phase AC power supply, and generate three-phase AC power in the motor. rotating magnetic field.

The utility model has the advantages of: a single-turn multi-turn continuous winding forming stacked winding, which can be directly wound into shape, has a simple structure, is easy to embed, does not need welding between turns, and has high reliability. It is especially suitable for use in high-power or High speed motor.
