Definitions
- the present invention relates to a stator of an electric motor for home appliances and a mold motor using the stator.
- the annular stator core is usually divided into half.
- the first phase coil 60 is first wound, leaving a space for the second phase coil, and then the second phase coil is wound in that space.
- the connecting wire connecting the coils comes into contact with coils of different phases. Therefore, before the second phase coil is wound, it is necessary to perform an insulation process such as attaching an insulating tape to the first phase coil 60 and the first phase connecting wire. It is desirable to have an insulation distance between the coil and the jumper that eliminates the need to apply insulating tape.
- stator core subjected to toroidal winding is resin-molded to be completed as a motor stator. Therefore, the structure of the stator core must be such that an insulation distance between the coil and the jumper is ensured even when a high pressure of the mold resin is applied.
- Patent Document 3 discloses an insulating groove for accommodating the jumper wire.

- FIG. 8 is a diagram of a terminal wire holding portion provided in the insulating cover.
- FIG. 9 is a view of the groove cover provided on the inner wall of the groove that accommodates the jumper wire.
- FIG. 10 is a diagram showing insulation of a jumper wire.
- Fig. 11 is another diagram showing insulation of the crossover wires.
- FIG. 12 is a diagram for explaining a conventional toroidal shoreline.
- a split stator core (hereinafter referred to as “stator core”) 1 in which an annular stator core is divided in half is provided with inner teeth 3 and outer teeth 4 on both sides of a yoke 2.
- An insulating cover 5 covers the stator core 1.
- the first phase, second phase, and third phase coils of the three-phase winding are sequentially wound in the slots between the teeth of the stator core 1 with toroidal winding. explain.
- the first-phase coils 11, 12, 13 are sequentially wound on the stator core 1 via the crossover wires 14, 15 connecting the coils.
- the second-phase coils 21, 22, 23 are sequentially wound on the stator core 1 via the jumper wires 24, 25.
- the crossover 24 crosses over the first phase coil 12.
- the crossover 25 crosses over the first phase coil 13.
- Third-phase coils 31, 32, and 33 are sequentially wound in the empty slots in FIG. 2 (see FIG. 4).
- the third phase crossover wires 34 and 35 cross over the already coiled first and second phase coils.
- the connecting wire of each phase intersects with the other phase coil under or on the coil.
- FIG. 3 is a partial perspective view of the stator core 1 in which the first phase coil and the second phase coil are wound.
- the insulating cover 5 has grooves 16 and 26 in the thick portion 6 where the third phase coil is to be wound.
- the first-phase crossover 14 is accommodated in the groove 16, and the second-phase crossover 24 is accommodated in the groove 26.
- the insulating cover 5 further has a guide post 7. The crossover 24 is guided by the guide post 7 so as to maintain a predetermined insulation distance 50 from the coil 12 when crossing the groove 26 and over the first phase coil 12.
- FIG. 4 is a perspective view of the stator core 1 in which the first phase, second phase, and third phase coils are wound.
- Both the third-phase crossover wires 34 and 35 are guided by the guide posts 7 so as to maintain a predetermined insulation distance from the first-phase and second-phase coils.
- the guide posts 7 are provided on the inner diameter side and the outer diameter side in order to separately arrange the jumper wires on the inner diameter side and the outer diameter side. This prevents contact between the crossovers.
- the crossover wires 34 and 24 are arranged separately on the inner diameter side and the outer diameter side.
- the connecting wires 25 and 35 are arranged separately on the inner diameter side and the outer diameter side.
- a guide post 7 having a separation wall 8 whose cross section is shown in FIG. 5 is used. Since the separating wall 8 separates the connecting wires, contact between the connecting wires is prevented even when guiding the connecting wires of different phases.
- FIG. 6 shows the stator core 1 set in the mold 40.
- the coil and the crossover of the stator core 1 need to be configured so as not to be deformed by the high flow rate of the resin flow from the mold gate 41 in order to maintain a predetermined insulation distance.
- the crossover wire and the heterogeneous coil are separated. By passing the connecting wire, for example, under the coil, it is possible to prevent the pressure of the resin flow from being applied to the connecting wire via the coil. When the crossover wire passes over the coil, the displacement of the crossover wire due to the grease flow can be minimized by shortening the distance between the guide posts.

- a cover 28 is provided on the inner wall of the groove 16 (see FIG. 3) of the insulating cover 5.
- the cover 28 holds the connecting wire in the groove 16 and prevents the coil that is wound in the thick portion 6 and the connecting wire from approaching.
- the insulating cover 5 does not have the thick part 6 and the groove 16 shown in FIG. Insulation sheet 30 is installed on the crossover to insulate between the crossover and the coil. Since there is no thick part 6, the stator thickness decreases. In addition to bonding, the insulating sheet 30 can be easily attached by providing an insulating sheet stopper 29 on the insulating cover 5.
- stator of the present invention Since the stator of the present invention has high reliability in the interphase insulation of the three-phase winding, it can be used not only for a brushless motor but also for an induction motor.
