Description

Generator rotor structure

The present invention relates to a generator rotor structure, and more particularly to a process that is simplified in processing, easy to maintain, and that avoids generation of magnetic losses and noise.

According to the conventional structure, the rotor structure of the generator is substantially as shown in FIG. 1 , and has a notch 11 at each end of the rotor for receiving the magnet 12 and positioning by the end cover 13 , but actually has the following Missing, need to be improved.

1. The silicon steel sheet needs to be punched separately, which not only takes time and labor, but also causes different punching and processing because of different output, different thickness of steel sheet and different quantity.

2. The rotor silicon steel sheet has the notch 11, which is easy to cause the incompleteness of the rotor magnetic field induction, and causes a magnetic loss or a noise spike when the mutual inductance is with the stator.

3. The magnet 12 is not easy to take out, which makes maintenance more inconvenient and inconvenient.

4. The notch 11 is provided at the peripheral end surface of the rotor. If the power conductor hole is to be added inside the rotor surface, the improvement of the magnetic pole path is hindered.

It is the primary object of the present invention to provide a generator rotor structure that is simplified in processing, easy to maintain, and that avoids magnetic losses and noise.

To achieve the above objective, the present invention provides a generator rotor structure, comprising: a body, which is composed of a plurality of silicon steel sheets, and at least one end of each of the outer peripheral surfaces has a card slot at each of the two sides, and the card slots are respectively The two end covers are disposed at two ends of the body, and each of the card slots has a latching device for engaging with the body and can accommodate the magnet; and a cover is disposed on the One end of the body is engaged with the one end cover; thereby simplifying the processing, facilitating maintenance, and avoiding the generation of magnetic loss and noise.

The latching device has a latching block that engages with the latching slot, and has a chamber above the latching block for receiving a magnet, and the latching block and the chamber have a slot on each side thereof. Corresponds to the channel.

The preferred features of the present invention, as well as the efficacies of the present invention, are described in detail in conjunction with the accompanying drawings, which are readily understood and recognized by those skilled in the art.

Referring to Figures 2 to 4, the rotor system of the present invention comprises:

A body 2 is composed of a plurality of sheets of silicon steel sheets, and the outer peripheral surface has at least one end corresponding to the two sides (for example, upper and lower sides or left and right sides), each having a slightly concave shape and extending axially. a card slot 21, the card slot 21 has a channel 22 on each side;

The two end caps 3 are disposed at the two ends of the main body 2. The end caps 3 each have a latching device 30 corresponding to the card slot 21. The latching device 30 has a slightly inverted T-shaped latch. The block 31 is engaged with the card slot 21, and has a chamber 32 above the card block 31 for receiving the magnet 33. The card block 31 and the chamber 32 have a defect on both sides. a slot 34 for engaging with the channel 22; and

A cover 4 is disposed at one end of the body 2 and is engaged with one of the end covers 3.

The intermediate body 2, the end cover 3 and the cover 4 have a uniform hole in the middle for respectively wearing a shaft (not shown).

According to the above configuration, the two end caps 3 are respectively engaged with the two ends of the body 2 by the latching device 30, and the magnets 33 are accommodated in the chamber 32 so that the magnets 33 are located on the outer peripheral surface of the body 2. In order to form the positive and negative electrodes, as shown in FIGS. 3 and 4, the latching block 31 is engaged with the card slot 21, and the notch 34 is aligned with the channel 22.

As can be seen from the above description, the present invention has at least the following advantages and effects, and is far more advanced than the prior art.

1. The body 2 (ie, the silicon steel sheet) can be integrally formed by punching, and has the card slot 21 and the channel 22, which is not only simplified in processing, but also easier to control its accuracy.

2. The magnet 33 is housed in the chamber 32 and located on the outer peripheral surface of the body 2 (the steel sheet), and is easy to take out or implant, which is more convenient and convenient for maintenance.

3. The magnet 33 is disposed on the outer peripheral surface of the body 2, and has no obstacle to the end surface of the body 2.

4. The magnet 33 is disposed on the outer peripheral surface of the body 2, and can maintain the integrity of the rotor end face and the magnetic field of the rotor. When it is mutually responsive to the stator, magnetic loss or noise spikes can be avoided.

5. The card slot 21 of the main body and the latching block 31 of the end cover can be firmly engaged with each other, so that the magnet 33 can be firmly positioned so that the rotor does not disengage due to centrifugal force when rotated.

5 to 7, the rotor of the second embodiment of the present invention also includes a body 2', a two-end cover 3' and a cover 4', wherein the body 2' has two ends at the outer peripheral surface thereof. Each of the side corresponding portions has a card slot 23, and the card slot 23 is slightly concave and axially extending. The card slot 23 has a channel 24 on each side of the card slot 23; the two end cover 3' is disposed on the body 2 The two ends of the card slot 23 have a latching device 30', and the latching device 30' has a slightly inverted T-shaped latching block 35 for engaging with the card slot 23. Correspondingly, the latching block 35 has a cavity 36 above it for receiving the magnet 37 so that the magnet 37 is located on the outer peripheral surface of the body 2', and the ends of the body 2' are formed with positive and positive The negative electrode, the clamping block 35 and the chamber 36 have a notch 38 on each side thereof to engage with the channel 24; the cover 4' is disposed at one end of the body 2' and is connected to the end cover One of the 3' snaps; thereby constructing the combination, and achieving the same advantages and effects as the first embodiment described above.

In summary, the specific embodiments disclosed in the present invention are found to be unsatisfied by the prior art, and achieve the intended purpose and effect, and are an invention that is novel, advanced, and has industrial value. Submit an invention patent application according to law.
