Two circular circular brush holders of the same structure are mounted on the mounting hole of the brush holder, and the internal structure of the brush holder can be designed according to the shape and size of the brush. A radial carbon brush sliding tube for installing a carbon brush is disposed inside the brush holder, and one end of the carbon brush in the sliding tube is in contact with the commutator on the rotor through the brush cap, the round copper piece, the copper brush and the spring; The other end is connected with a copper brush, and a round copper piece is connected to the end of the brush. The copper piece is in contact with the copper piece in the brush holder, and the copper piece also has the effect of balancing the brush cap on the pressure of the carbon brush, so that the carbon brush and The force between the commutators is uniform. The diameter and spring force of the spring between the carbon brush and the round copper should be selected according to the different motor models. The two lead wires are taken out from the copper lead terminal inside the brush holder and the external power supply. The connection is. The design of the external carbon brush is designed to have a large contact pressure drop, especially a brush with a steep volt-ampere characteristic. Because the brush and the commutator have just started a running-in phase, the motor noise is relatively large during this running-in phase. In order to achieve stable normal operation in the shortest possible time, a brush with a slope is designed. This kind of brush not only has a short running-in time, but also has less contact surface between the brush and the commutator, and the noise is relatively lower than that of the ordinary carbon brush. However, there are also disadvantages, the contact surface with the commutator is small, and the brush is affected. The force is not uniform, and it is easy to produce sparks and motor jam. The other brush is a circular arc brush, and its contact end with the commutator is curved. This type of brush is compared with the commutator contact surface. Many, the cooperation with the commutator is better, the force of the brush is relatively uniform, but because the contact surface of the brush and the commutator is relatively large, the sound and sound of the motor running, the running-in time is relatively longer, combined with the above two The characteristics of the brush, we have developed a circular arc toothed brush, which combines the advantages of the above two brushes, processing several small teeth on the arc surface of the arc row brush In this way, when the motor is running, the brush not only receives the force evenly, but also eliminates some bad accidents caused by the unilateral force of the brush, and the running-in process of the arc-shaped toothed brush is also fast, reducing Motor noise, compact with built-in splint gearbox
Pixel filter, referring to the arrangement of RGB channels in color filters, arranges multiple micron level spectral channels into a spectral period according to a certain pattern. The pixel filter can be customized according to the detector pixel size to achieve one-to-one alignment of the spectral channels and detector pixels.
