Abstract

The utility model provides an insulating framework convenient for stator winding fixing and a motor thereof. The coil winding is in the ring channel, and the ring channel not only fixes a position the coil winding, avoids the coil to take place to slide, has still improved the winding efficiency of coil.

Description

Insulating skeleton convenient to stator wire winding is fixed and motor thereof

Technical Field

The utility model relates to the technical field of motors, in particular to an insulating framework facilitating stator winding fixation and a motor thereof.

Background

The stator bobbin generally includes a coil bobbin for winding a wire and a terminal bobbin for mounting a conductive terminal. Generally, the stator bobbin is generally one molded integral piece, that is, the coil bobbin and the terminal bobbin are integrally formed by molding. In the manufacturing process of the motor, an integrally formed stator frame is usually pressed into the stator, then a wire (e.g., an enameled wire) is wound on the coil frame to form a coil, then a lead end of the coil is pressed into a wire pressing groove on the terminal frame, and finally, a conductive terminal is pressed into a conductive terminal groove on the terminal frame so as to be electrically connected with the lead end of the coil.

The skeleton generally includes baffle and the winding body that mutual integrated into one piece connects, and the copper line supports to lean on the baffle, and the winding is on the winding body outer lane. However, since the outer coil of the winding body is smooth, the coil is easy to slide after being wound and even to separate from the winding body.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: the technical problem that a coil wound on a traditional stator framework is easy to slide and even separate is solved.

The utility model provides an insulating framework convenient for stator winding fixation, which comprises a baffle and a winding body which are integrally connected with each other, wherein a plurality of annular grooves which are arranged at intervals in parallel are arranged on the winding body.

The coil winding is in the ring channel, and the ring channel not only fixes a position the coil winding, avoids the coil to take place to slide, has still improved the winding efficiency of coil.

This problem is further improved since the coil is not sufficiently securely mounted by the annular groove, in particular, located close to the baffle. So set up, the coil supports and leans on the baffle to in the winding of ring channel, the installation is more firm.

Further, the annular groove covers the area of the wrap outer wall 3/5-2/3. So set up, ensure the intensity of winding body.

The traditional baffle is a closed annular plate, and the position accuracy of the coil abutting against the baffle is low, so that the problem is further improved and solved. The gap is convenient for the hand to apply force to the coil, so that the position precision of the coil is higher.

The utility model also provides a motor which comprises a stator, wherein the stator is provided with an insulating framework convenient for fixing the stator winding and used for winding coils. So set up, the motor stable performance.

Drawings

The utility model is further illustrated with reference to the following figures and examples.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a front view of the present invention;

in the figure: 1. a baffle plate; 2. a winding body; 3. an annular groove; 4. a notch; 5. the joint board.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

The first embodiment is as follows:

as shown in fig. 1 and 2, the utility model provides an insulating framework convenient for fixing a stator winding, which comprises a baffle plate 1, a winding body 2 and a clamping plate 5 which are integrally formed and connected in sequence. The winding body 2 is provided with a plurality of annular grooves 3 which are arranged in parallel at intervals. The clamping plates 5 are arranged in a plurality of rotation symmetry for clamping and mounting the framework.

The coil winding is in ring channel 3, and ring channel 3 not only fixes a position the coil winding, avoids the coil to take place to slide, has still improved the winding efficiency of coil.

Example two:

compared with the first embodiment, the differences are as follows: the annular groove 3 is located close to the baffle 1. So set up, the coil supports and leans on baffle 1 to twine in ring channel 3, the installation is more firm.

Example three:

compared with the two examples, the difference is that: the annular groove 3 covers the outer wall 3/5 area of the winding body 2. With this arrangement, the strength of the wound body 2 is ensured.

Example four:

compared with the three phases of the embodiment, the differences are as follows: the annular groove 3 covers the outer wall 2/3 area of the winding body 2.

Example five:

compared with the two examples, the difference is that: the baffle 1 is provided with a plurality of uniformly distributed gaps 4, and the annular groove 3 closest to the baffle 1 is divided into uniformly distributed multiple sections by the gaps 4. The gap 4 is convenient for the hand to apply force to the coil, so that the position precision of the coil is higher.

Example six:

the utility model also provides a motor which comprises a stator, wherein the stator is provided with any one of the first embodiment to the fifth embodiment of the insulating framework which is convenient for fixing the stator winding and is used for winding a coil. So set up, the motor stable performance.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
