Description
Technical field
The utility model discloses a kind of externally-wound type motor stator.
Background technology
Motor is a kind of calutron realizing electric energy conversion according to the law of electromagnetic induction or transmit.It forms primarily of stators and rotators, and wherein said stator comprises stator core and is embedded in the coil on iron core.This structure adopts traditional wire insertion technology, and not only production efficiency is low, and manufacturing cost is high.
Utility model content
The purpose of this utility model is to provide a kind of externally-wound type motor stator, and this motor stator manufactures easy, and coil directly around on stator core from outer, simplify frock, improves production efficiency, reduce manufacturing cost.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of externally-wound type motor stator, comprise outer iron core and interior iron core, described outer iron core is together with interior iron core close-fitting, described interior iron core is provided with a circle winding slot, this winding slot is provided with coil, the outer wall of this winding slot is provided with notch, and coil can enter from this notch and be arranged on described interior iron core.
Further setting as such scheme: be circumferentially evenly provided with 8 coils on interior iron core.
Described winding slot groove depth is a is 9 ~ 9.5mm, and slot opening b is 2.4 ~ 2.6mm.
Described winding slot groove depth is a is 9.15mm, and slot opening b is 2.5mm.
After adopting said structure, the utility model manufactures easy, and coil enters in winding slot from the outer notch directly namely from winding slot on stator core, compared with prior art simplifies frock, improves production efficiency, reduce manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model outer iron core structural representation;
Fig. 3 is core structure schematic diagram in the utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of externally-wound type motor stator, comprise outer iron core 1 and interior iron core 2, described outer iron core 1 is together with interior iron core 2 close-fitting, described interior iron core 2 is provided with a circle winding slot 3, this winding slot 3 is provided with coil 4, the outer wall of this winding slot 3 is provided with notch 5, coil can enter from this notch 5 and be arranged on described interior iron core 2.Described winding slot 3 groove depth is a is 9 ~ 9.5mm, and slot opening b is 2.4 ~ 2.6mm.
The present embodiment is circumferentially evenly provided with 8 coils 4 on interior iron core 2; Described winding slot 3 groove depth is a is 9.15mm, and slot opening b is 2.5mm.
The utility model coil 4 is by notch 5 from external enwergy around interior iron core 2, and which simplify frock, reduce cost, coil 4 is located at after on winding slot 3, and outer iron core 1 close-fitting, on interior iron core 2, prevents coil from deviating from.After the utility model energising, coil 4 produces magnetic field, and after rotor being arranged on interior iron core 2, rotor can rotate.
