   Starter Armature It is a core component of the automobile engine starting system and an important part of automotive electronic technology. From the initial direct start to the current electric start, the development of the starter armature has gone through a long process.

  As early as the beginning of the 20th century, automobile starting used a simple hand-cranking method, then developed into more efficient pneumatic starting, and then into more popular and practical electric starting. The development of the armature part of the electric starter can be traced back to 1903 in the United States. At that time, an engineer named Frank J. Ward invented the electric starter. This electric starter consists of a set of armatures and a permanent magnet control switch.

  From the early to the mid-20th century, the armature part of the starter was still relatively simple. It usually consists of a motor, armature, water pipe, cam drive, etc. In 1948, Germany's Robert Bosch GmbH developed a wound-type starter armature. By the 1980s, the rapid development of electronic technology led to a huge increase in the demand for automotive electrical appliances. Semiconductor components and IGBTs began to be used in starter armatures. After a long development process, modern automobile starters are no longer simply motor parts, but multifunctional high-tech automotive parts.

  The starter armature is not only a key component for starting the automobile engine, but also has multiple functions, such as power generation, charging, emergency starting, external power supply, etc., supporting the intelligent and information development of automobiles. The development of the starter armature has profoundly affected the performance and stability of automobile engines and promoted the substantial development of the automobile industry.

  The vehicle starter is an important component. Its working principle is to generate magnetic force through the armature current to drive the engine to rotate. However, if the starter armature is used improperly, it may cause the vehicle to fail to start or damage the motor. To avoid this, the following precautions for the starter armature should be noted:

  The electrodes of the starter armature should meet the manufacturer's recommended standards. If inappropriate electrodes are used, it may cause armature damage or armature heating, affecting the normal operation of the engine.

  The starter armature should be cleaned and maintained regularly. If dust and dirt accumulate on the armature, it may hinder the current transmission of the armature and affect the vehicle's starting effect.

  The starter armature cannot be idled for a long time. If the starter armature rotates without current, it may cause armature damage, thereby affecting the normal operation of the engine.

  The current load of the starter armature should meet the standard. If the armature is overused, the current to the armature may increase, thereby damaging the armature or causing high armature temperature.

  Overuse or prolonged operation of the starter armature will cause the armature to overheat. If the armature is found to be overheating, stop using it and check whether the armature's current load exceeds the standard range.

Starter motor armature manufacturer: What are the characteristics of the armature?

Starter armature manufacturer introduction: Whether it is a DC motor or an AC motor, and regardless of whether the winding is placed on the rotor or stator, it belongs to the armature winding placed in the iron core slot. It is only because of the different connection methods of the winding that different types and characteristics are obtained. In order to strengthen the mechanical fixation of the winding, its effective (straight) part is placed in the slot. But the ending is still an invalid part, only playing a connecting role. The starter armature manufacturer believes that the winding embedded in the slot also brings some problems. First of all, in order to prevent tooth saturation, the air gap magnetic density has to be limited, which limits the utilization coefficient of the motor. Second, the voltage of the motor cannot be too high. Third, the inductance of the coil becomes larger, which is related to the saturation of the iron core. In this way, for electric drive and servo systems, the response speed of the motor becomes slower, and the nonlinearity of the inductance complicates the control system. Therefore, in the development of large steam turbine generators, especially the emergence of superconducting motors, as well as DC motors and control motors, slotless motors have appeared. The starter armature manufacturer believes that slotless DC motors are mainly used for the control of DC traction motors and small DC motors. The iron core of the slotless motor is a cylindrical yoke, which is wound with an insulating layer or fitted with a prefabricated insulating tube. Then, the winding elements are evenly distributed on its surface.

Starter armature manufacturer: Common sense of armature

The starter armature manufacturer indicates that the winding is the heart of the motor. Different motors, different manufacturers, and different processing technologies will correspond to different winding types. Different winding types are selected according to the specific characteristics to be achieved, requiring simple structure, convenient manufacturing and maintenance, and safe and reliable operation. The armature winding of a DC motor is the same as that of an AC motor. The relationship between the coils should be such that a certain number of conductors produce a large potential difference, saving as much non-ferrous metal and insulating material as possible. However, it also has its unique features: the coils are connected by a commutator, and the connection relationship must ensure good commutation. The starter armature manufacturer indicates that the armature windings of DC motors can be divided into five types: single winding, lap winding, single wave winding, multiple wave winding, and frog winding, i.e., a mixed winding of lap winding and wave winding. In a single lap winding, adjacent elements under the same magnetic pole are connected in series, and the pitch y=yk=1 or -1. When winding this type of winding, any two series-connected elements directly overlap each other, so it is called a lap winding. If y=yk=1, the winding moves to the right, which is called a "right-hand" winding; if y=yk=-1, the winding moves to the left, which is called a "left-hand" winding. Each element of the left-hand winding is connected to two short lines of the commutator, using copper.

Overview of Automotive Armature

In the process of electromechanical energy conversion in a motor, the automotive armature plays a key and pivotal role. For a generator, it is the component that generates electromotive force. Let's take a detailed look at the automotive armature. The automotive armature is the component in the motor that carries the coil, and the relative movement of the coil and the magnetic field. In a generator, the induced electromotive force is generated in the coil, and the coil rotates under force to generate electricity. In a motor, the energized coil is subjected to Ampere force in the magnetic field, causing it to rotate in the magnetic field. Since the automotive armature plays a very important role, you should know that in fact, part of an AC generator or related equipment can be represented in mechanical or electrical terms. Although clearly separate, note that these two sets of terms are often used interchangeably, or include a combination of mechanical and electrical terms. This can lead to confusion when using composite machines such as brushless AC generators, or when talking between people accustomed to using differently configured machines. Therefore, in most generators, the excitation magnet rotates and is part of the rotor, while the automotive armature is stationary and part of the stator. Motors and generators can be constructed with a stationary armature and rotating magnetic force or a rotating armature and stationary magnetic force. The demagnetization effect of the automotive armature can be...
