  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.

How to identify automotive armature windings?

The armature winding of an automobile is the heart of the motor. Different motors, manufacturers, and processing technologies correspond to different winding styles. Different winding styles are chosen to achieve specific characteristics, such as simple structure, easy manufacturing and maintenance, and safe and reliable operation. The automobile armature winding, like the AC motor winding, has a significant potential difference between the edges of each coil for a specific number of conductors. It should save non-ferrous metals and insulating materials as much as possible, but it has unique characteristics. Through the connector between coils, the connection relationship must ensure good conversion. I. Characteristics and coil pitch of automobile armature winding The characteristics of automobile armature winding are usually represented by the number of slots, the number of coils, the number of commutator segments, and various coil pitches. Each coil has two coil sides, and each commutator segment connects coil sides and coil sides, so the number of coils S must be equal to the number of commutator segments K (for example, S=K). 1. One pitch y1 The distance between the two coil sides of each coil intersecting the armature surface is called the back coil pitch or one coil pitch of the winding, represented by the number of virtual slots intersected. 2. Two pitches y2 In two coils connected by the same translation layer section, the distance between the bottom coil side of one coil and the top coil side of the other coil from the armature surface is called the front coil pitch or two coil pitches,

Induced electromotive force and current of automotive armature windings

The basic understanding is that when a current flows through the armature winding in a magnetic field, a force acts on the winding. A more advanced understanding is that when a current flows through the winding in a magnetic field, another magnetic field is generated, and the interaction between the two magnetic fields produces torque. From an electron's perspective, the current experiences a force in the magnetic field. The latter understanding is that two magnetic fields interact with each other. Generally understood as a magnetic field that generates induced electromotive force, and the current in the winding generates another magnetic field, and the interaction between the two magnetic fields generates torque. However, if the two are combined into one magnetic field, how this magnetic field generates torque needs to understand the tensor law. The magnetic force that generates the armature induced electromotive force is called the air gap magnetic flux line, and the magnetic chain is called the air gap magnetic flux line. The air gap magnetic flux line and the induced armature will reduce the frequency relationship, thereby reducing the pi/2 phase relationship. This is a very clear and measurable physical quantity. The relationship with the armature winding current is also obvious. There are two main types of flowing armature windings, used in DC motors and AC motors respectively. The armature consists of an armature core and an armature winding. The armature winding is the circuit part of a DC motor, and is the part that converts electrical energy by generating induced electromotive force and electromagnetic torque (a generator is the part that converts mechanical energy into electrical energy). The armature core is the electric

The function of an automotive armature

The automotive armature is a core component in the process of converting mechanical energy and electrical energy in a motor. For generators, it is the component that generates electromotive force, such as the rotor and stator of a DC generator and the stator of an AC generator. For motors, it is the component that generates electromagnetic force, such as the rotor and stator of a DC motor. The automotive armature is the component of the motor that has coils, and these coils move relative to the magnetic field. In a generator, the rotating coils under force generate an induced electromotive force, thus generating electricity. In a motor, the coils are subjected to Ampere's force in the magnetic field, causing them to rotate in the magnetic field. In most generators, the field magnet is part of the rotating component, and the armature is stationary, part of the stator. Motors and generators can be composed of a stationary armature and a rotating magnetic field or a rotating armature and a stationary magnetic field. Permanent magnets or the polarized parts of electromagnets and the moving iron parts of solenoids (especially when the latter are used as switches or relays) can also be considered armatures. Composition of an automotive armature: Automotive armature windings are divided into two main categories: DC armature windings and AC armature windings. They are used in DC motors and AC motors respectively. The automotive armature consists of an armature core and armature windings. The armature windings are the circuit part of the DC motor, formed by...
