  Recently, Hanwha Electroparts Company, in response to a call, organized party members, cadres, and employee representatives to visit a cinema to collectively watch the large-scale documentary "Amazing China", witnessing the glorious achievements of the motherland's development and feeling the national pride of the new era.
  Guided by the new era of socialism with Chinese characteristics, the film presents, in documentary form for the first time on the big screen, the development achievements and trajectory of China over the five years since the 18th National Congress of the Communist Party of China, as well as the major statement of "Entering a New Era of Socialism with Chinese Characteristics" put forward in the 19th National Congress report.
  Throughout the film, "Amazing China" showcases the "great power style" through various perspectives such as the dream projects, technological innovation, and green China, demonstrating the coordinated development of the "five-in-one" approach of the cause of socialism with Chinese characteristics; it also showcases the "four confidences" of the Chinese people in the new era through the images and stories behind super projects such as Chinese bridges, roads, cars, and ports.
  "Amazing China" uses "great nation" and "small family" as intertwined themes, focusing on the "great nation" while also highlighting the "small family." This adds a touching element to the grand scale of the film. Behind every "Chinese miracle" lies the participation and contribution of ordinary people. The greatness of the nation stems from the collective efforts of every citizen. The achievements of the nation are reflected in the better lives of every citizen.
  From watching the film to reflecting on ourselves, as Hanwha people, although we are not at the forefront of the nation's major projects, we can still feel pride and self-esteem in our daily hard work, providing the world with the highest quality armature products and continuously striving for a better life for the Chinese people.
  "Shocking, heartwarming, and proud"—these three words lingered in my mind after watching "Amazing China." I was shocked by China's strong national strength, its rapid development, and the hard work and ingenuity of the Chinese people. The engineers' persistence over a decade, the heartwarming grassroots work of the Tibetan poverty alleviation girl, and the return of Chinese people from Yemen all reflect the Party and the state's care for the people, giving us a strong sense of identity, belonging, security, and pride towards our motherland. Since the 18th National Congress of the Communist Party of China, the Party Central Committee with Comrade Xi Jinping at its core has remained true to its original aspiration and forged ahead, using concrete actions to achieve remarkable achievements, proving to the Chinese people and the world what confidence in the path, theory, and system means. The confidence of the Chinese people has been unprecedentedly consolidated, making everyone deeply feel that they have a strong motherland behind them. With the creation of one Chinese miracle after another and the writing of one Chinese story after another, I can't help but shout from the bottom of my heart: Amazing China!
  After the film, everyone expressed their feelings, saying that they would strive to demonstrate the excellent qualities of the Chinese people in their respective positions and roles, and contribute their modest efforts to the great development of the Sandan Horse Farm.

Introduction to the role of the stator and rotor in a brushless motor - collect this information!

The stator and rotor of a brushless motor consist of permanent magnets with a certain number of magnetic poles embedded in or on the surface of the iron core. Most permanent magnets are made of rare-earth permanent magnet materials with high coercivity, such as neodymium, iron, and boron, and high magnetic permeability and magnetic induction density. The rotor magnets are similar to those in brushed motors; both produce a sufficient magnetic field in the air gap of the motor. The difference is that the permanent magnets in brushed motors are mounted on the rotor, while those in brushless DC motors are mounted on the stator. The rotor system structure of brushless DC motors often adopts different surface-mounted magnets, also known as tile magnets, with radially magnetized tile-type permanent magnets bonded to the outer surface of the iron core. Through reasonable design, a square-wave air gap magnetic flux density can be obtained. What is the injection molding process for the stator and rotor of a brushless motor? Metal inserts are placed in the mold, and then BMC plastic is injected and heated to 160 degrees. The power of the motor should be selected according to the power required by the equipment, so that the motor operates under rated load as much as possible. Two points should be noted when selecting: (1) If the motor power is too small, a "small horse pulling a large cart" phenomenon will occur, causing the motor to be overloaded for a long time and damaging it.

What are the components of a starter motor armature?

The control device of the starter armature includes an electromagnetic switch, a starter relay, and an ignition start switch, etc., among which the electromagnetic switch is made together with the starter armature. I. Electromagnetic switch 1. Structural characteristics of electromagnetic switch The electromagnetic switch is mainly composed of an electromagnetic iron mechanism and a motor switch. The electromagnetic iron mechanism is composed of a fixed iron core, a moving iron core, an attracting coil, and a holding coil. The fixed iron core is fixed, and the movable iron core can move axially in the copper sleeve. The front end of the movable iron core is fixed with a push rod, and the front end of the push rod is provided with a switch contact plate. The rear end of the movable iron core is connected to the fork through an adjusting screw and a connecting pin. The reset spring is arranged outside the copper sleeve to reset the movable parts, such as the movable iron core. 2. Working principle of electromagnetic switch When the directions of the magnetic fluxes generated by energizing the attracting coil and the coil are the same, their electromagnetic attractions overlap each other, and the moving iron core can be attracted to move forward. The pad at the front end of the push rod until the electrical switch contacts are connected to the motor main circuit. When the magnetic pain caused by the energization of the attracting coil and the coil is in the opposite direction, their electromagnetic attractions cancel each other out. Under the action of the reset spring, the movable iron core and other movable parts automatically reset, the pads and contacts are disconnected, and the motor main circuit is disconnected. II. Starting relay

What is the manufacturing method for the starter armature structure?

The starter armature structure can increase the energization time of the starter and avoid the problem of short circuit caused by the ablation of the copper wire winding after the armature is energized for a long time, thus ensuring the safety of the circuit. The starter armature structure includes an armature shaft, an armature winding, an iron core and a commutator. The armature winding includes an end winding i arranged away from the commutator. The end winding i is provided with a U-shaped portion, and the U-shaped portion is provided with an insulating sleeve. The melting point of the insulating sleeve is higher than 200 ℃. The iron core is fitted on the armature shaft, and the iron core is provided with a winding slot i, and the armature winding is embedded in the winding slot i. An insulating piece i is set in the winding slot i to isolate the armature winding from the iron core and the edges of the components of the armature winding. The insulating piece i has an S-shape structure to wrap the edges of the components of the armature winding. The commutator is fitted on the armature shaft and is arranged near the end of the armature shaft. The commutator is provided with a winding slot ii. The armature winding also includes an end winding ii, which is arranged near the commutator and embedded in the winding slot ii. The end winding ii is composed of an inner ring layer and an outer ring layer, and an insulating element ii is arranged between the inner ring layer and the outer ring layer to isolate the inner ring layer and the outer ring layer. The clamping ring is also fitted at a position corresponding to the winding slot ii on the commutator. The insulating sleeve is made of glass fiber.
