Abstract

PURPOSE:To improve the utility efficiency of the space in a motor and to facilitate the winding work by winding an armature coil, inserting it into an armature core, and forming the structure of the armature coil of the motor to be engaged with an armature coil cover. CONSTITUTION:After an armature coil 8 which is fusion-bonded and shaped is inserted into pole pieces 7 of armature core in which silicon steel plates of high magnetic permeability material are laminated, an armature coil cover 9 made of high magnetic permeability material is engaged. By altering the sequence, the coil 8 may be engaged with the armature coil after the coil 8 is fixed to the cover 9.

Description

[Detailed description of the invention] The present invention, 11! The present invention relates to a motor in which the armature winding cover of the armature core Kff is installed by one person after inserting and fixing 11 armature windings, which have been fixed and fixed in advance, into the armature core with the tooth width of the frame pieces of the steel core being constant.

The armature winding structure of a conventional electric motor has a semi-closed slot structure as shown in FIG. 1, in which a 1VC armature winding core 2 is wound. Here, part A in the center of the armature core is called a frame piece. In the structure shown in Fig. 1, in order to prevent magnetic saturation and magnetic flux leakage of the armature core, the shape of the frame piece of the armature core is complicated, which not only complicates the winding work, but also
The efficiency of the eleventh space occupied by the pusher winding is also poor. In addition, in order to improve the utilization efficiency of the space occupied by the armature winding, even if the number of frame pieces of the armature core is increased, the air gap between adjacent pole pieces is reduced, making the winding work easier. It becomes even more complicated. Therefore, not only is it unsuitable for making electric motors smaller and thinner, but it is also difficult to assemble.

Further, as an example of the structure of the armature winding part of Sen's conventional lightning/motor, there is a flat type as shown in FIG.

In FIG. 2, the rotor magnet 4 is fixed to the rotor yoke 3, and the stator coil 5 is fixed to the substrate 6. In this example, the two cheetah coils corresponding to the previous iii'Y armature winding are made by pre-forming the winding ζf''1. Compared to the iron core type, the air gap magnetic flux density between the bellows rotor magnet and the stator coil is smaller, and the torque and efficiency as a motive force are inferior.

The present invention eliminates these drawbacks, and its purpose is to make the electric motor smaller and thinner. Another purpose is to simplify and facilitate the work of winding a single frost coil in a Vi electric motor, and to make it possible to accommodate a special VCpm coil with four coils. Yet another purpose! The purpose is to improve the utilization efficiency of the space occupied by the rotary winding. Still another objective is to improve torque drawing and gravity efficiency as an electric motor.

The present invention will be explained in detail below based on examples.

FIG. 3 shows the structure of the electrical winding portion of the present invention, in which the 1j machine winding is heat-sealed and formed on the frame piece 7 of the single machine core laminated with silicon steel plates, which are high magnetic permeability materials. After inserting and fixing 8, insert the lII machine winding cover made of high magnetic permeability material. Place the armature winding first.

It can be fixed to the armature winding cover or inserted into the military armature core. Furthermore, Fig. 4 shows an armature winding cover ring 1o made of a high magnetic permeability material, which has a form in which the front power distribution and root winding cover are connected in a cylindrical shape, and the number of pole pieces is large and #Vc.
@π is valid. The square hole in the center of 1o can be omitted as long as the positioning is correct.

FIG. 5 shows a sectional view of a lightning bolt and a motive device as an embodiment to which the present invention is applied. In Figure 5, 11 ke 1! Kajimaki cover, 1

The axis rotates. As seen in FIG. 5, the space utilization efficiency of the armature winding is improved, and by increasing the number of pole pieces, the space utilization efficiency is further improved. However, since the armature winding is pre-formed, it is always easy to do so. In addition, by making the air gap between the rotor magnet and the armature core sufficiently small ζ, sufficient air gap magnetic flux can be obtained, and torque characteristics and power consumption characteristics are improved.

As shown in the example on the leg! After the armature winding is formed, the armature winding is inserted into the joint core and the armature winding cover is fitted.By adopting this structure, the space utilization efficiency inside the motor is improved and the motor is compact. π enables thinner and thinner design
[It is easy to wind the wire, enables high torque and high power efficiency, and can be applied to small electric motors.
