Description

Motor core structure

The invention relates to a motor structure, in particular to a motor core structure.

The existing motor includes a stator and a rotor. The stator and the rotor of the motor may also be referred to as a core. The stator is a ring-shaped structure, and the rotor is a cylindrical structure. The stator and the rotor are each a plurality of The silicon steel sheets are stacked, and the stator is taken as an example. As shown in FIG. 7 to FIG. 9 , each of the silicon steel sheets 90 has an annular structure, and each of the top steel sheets 90 is provided with a plurality of positioning concave portions 91 in the top ring spacing ring, and then The laminated silicon steel sheets 90 are concavely and convexly engaged with each other through the plurality of positioning concave portions 91, and the plurality of steel sheets 90 are superposed through each other to have a thickness of the motor core.

The motor core is structurally only directly overlapped by a plurality of silicon steel sheets 90. Therefore, when the existing motor is used, the magnetic lines of force pass through a plurality of steel sheets 90, that is, the magnetic lines of force run in the motor core. The motor core itself has a magnetic resistance, which will make the magnetic line slow down, that is, hysteresis. The hysteresis will cause loss. This loss phenomenon is called hysteresis loss. In addition, because the magnetic lines run in the motor core. In the process, there will also be turning and turning, which is the eddy current phenomenon, and the eddy current phenomenon will also cause loss. This loss phenomenon is called eddy current loss, and the existing steel sheets 90 of the existing motor are directly overlapped, so The hysteresis loss of the magnetic force and the eddy current loss are particularly remarkable, and the output efficiency of the motor is not good, so it is necessary to improve.

In order to reduce the loss of the magnetic flux itself and the loss caused by the eddy current phenomenon, the main purpose of the present invention is to provide a motor core structure, which is mainly provided with electrical insulation between the upper and lower laminated silicon steel sheets. The colloid allows the magnetic lines to run only in the respective silicon steel sheets, which greatly reduces the chance of eddy currents, thereby greatly reducing the eddy current loss during operation to improve the output efficiency of the motor.

The present invention solves the prior art problem of the motor core structure, which comprises: a plurality of silicon steel sheets; a plurality of layers of electrically insulating colloids, each layer of electrically insulating colloid disposed between the upper and lower steel sheets.

In the foregoing motor core structure, the electrically insulating colloid is annularly disposed between the upper and lower steel sheets, so that a gap is formed between the upper and lower steel sheets without the electrical insulating colloid.

In the foregoing motor core structure, the plurality of layers of the electrically insulating colloid are integrally covered between the upper and lower spaced steel sheets, so that the upper and lower steel sheets are covered with an electrically insulating colloid.

The improved efficiency of the novel technical means is as follows: the present invention applies an electrically insulating colloid to the upper and lower spaced silicon steel sheets, so that an electrically insulating colloid is provided between the upper and lower spaced silicon steel sheets, and then the electromagnetic During the operation of the iron, the magnetic lines cannot pass through the electrically insulating colloid, so that the magnetic lines can only run in the respective silicon steel sheets, which can greatly reduce the chance of forming eddy currents. Therefore, the novel can greatly reduce the motor core during operation. Eddy current loss phenomenon.

In order to understand the technical features and practical effects of the present invention in detail, and in accordance with the novel content, the following further describes the preferred embodiment as shown in the following figure:

A first preferred embodiment of the motor core structure provided by the present invention is shown in Figures 1 to 3, which includes a plurality of silicon steel sheets 10 and a plurality of layers of electrically insulating colloid 20, wherein:

Each of the silicon steel sheets 10 is an annular sheet body, and the electrically insulating colloids 20 are annularly spaced between the upper and lower steel sheets 10 so that no gap is formed between the upper and lower steel sheets 10 without the electrical insulating colloid 20 The finished product of a plurality of silicon steel sheets 10 stacked is shown in FIG. The electrically insulating colloid 20 forms a tough thermosetting plastic through a colloid curing process. If the colloid curing process is a heating procedure, the colloid curing process has a heating range of 100 ° C to 250 ° C, if the colloid is cured. The program is a pressurizing program, and the pressing force of the pressurizing program is 2000 kgf to 10000 kgf.

A second preferred embodiment of the motor core structure provided by the present invention is as shown in FIG. 5 and FIG. 6, which is substantially the same as the first preferred embodiment, except that the majority of the electrically insulating colloids are completely intact. Covering between the upper and lower spaced silicon steel sheets, an electrically insulating colloid 20 is disposed between the upper and lower steel sheets 10 .

In summary, the present invention applies an electrically insulating colloid 20 between the upper and lower steel sheets 10 to provide an electrically insulating colloid 20 between the upper and lower laminated silicon steel sheets 10, and the novel motor core is During the operation, the magnetic lines of force cannot pass through the electrically insulating colloid 20, so that the magnetic lines can only run in the respective silicon steel sheets 10, and the chance of forming eddy currents is greatly reduced, so the novel can greatly reduce the motor core during operation. Eddy current loss phenomenon.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Any person having ordinary knowledge in the art can use the present invention without departing from the technical features of the present invention. Equivalent embodiments of the novel modifications or modifications made by the novel teachings are still within the scope of the novel features.
