   Automotive Armature As a new type of energy-saving, CNC integrated motor, it shoulders the important task of revolutionizing the existing motor structure to achieve the goal of more energy-saving and longer-life motor innovation. Below, we will discuss the precautions for using automotive armatures?

  There are also some precautions when using an automotive armature. For example, before disassembly, use compressed air to blow away dust from the surface of the motor and wipe off surface dirt. Choose a suitable location for disassembling the motor and clean the surrounding environment. It is also necessary to be familiar with the structural characteristics and maintenance technical requirements of the automotive armature. Only in this way can the necessary tools and equipment for disassembly be prepared. To further understand the defects in the operation of the automotive armature, if possible, an inspection test can be carried out before disassembly. For this purpose, the automotive armature is placed under load for a trial run, and the temperature, sound, vibration, etc. of each part of the motor are carefully checked, and the voltage, current, and speed are tested. Then, the load is disconnected, and a no-load test is performed separately to measure the no-load current and no-load loss, and records are made. After all these are completed, the power can be cut off, the external wiring of the motor can be removed, and records should be made.

  When using an automotive armature, a megohmmeter with a suitable voltage must be used to test the insulation resistance of the motor. In order to compare the insulation resistance value measured during the last inspection and judge the change trend and insulation state of the automotive armature, the insulation resistance values measured at different temperatures should be converted to the same temperature, generally 75℃. Next, the absorption ratio K needs to be tested. When the absorption ratio is greater than 1.33, it indicates that the automotive armature insulation has never been damp or the degree of dampness is not serious. In order to compare with previous data, the absorption ratio measured at any temperature also needs to be converted to the same temperature. Regularly check whether the sound of the automotive armature during operation is normal. If there is an abnormal sound, the machine must be stopped immediately for inspection, because the most worn part in the entire brushless motor is the bearing part. If there is an abnormal sound, it is very likely that the bearing is worn. If the wear is excessive, the bearing can be replaced and continued to be used. However, if the bearing is not replaced and continued to be used, the friction during the swinging and rotating process will accelerate the wear of other parts of the brushless motor, which will definitely accelerate the wear of the entire automotive armature.

  After the introduction of the above content, we have a further understanding of the precautions for using automotive armatures. We will no longer feel unfamiliar when we see it again, and problems will not occur frequently during use. Okay, that's all for today's content. I believe there will be more exciting knowledge points to come.

P-gear armature: What is an armature

The armature manufacturer states that motors play a key and crucial role in the process of realizing the mutual conversion of mechanical energy and electrical energy. For generators, it is the component that generates electromotive force, such as the rotor in a DC generator and the stator in an AC generator; for motors, it is a component that generates electromagnetic force, such as the rotor in a DC motor. The armature manufacturer states that the armature is the relative motion of the coil relative to the magnetic field of the coil-carrying component in the motor. In a generator, an induced electromotive force is generated in the forced rotating coil to generate electricity. In a motor, the energized coil is subjected to the Ampere force in the magnetic field, causing it to rotate in the magnetic field. In the mid-19th century, the term "armature" was early used for inductors, i.e., holders of magnets. Part of an alternator or related equipment can be represented by any mechanical or electrical aspect. Although these two sets of terms are clearly separated, they are often used interchangeably, or a combination of mechanical and electrical terms is included. This can cause confusion when using composite motors such as brushless alternators, or when talking to people accustomed to using different configurations of motors. In most generators, the field magnet is rotating and is part of the rotor, while the armature is stationary and is part of the stator. Motors and

What is the function of the fuel pump armature?

The fuel pump armature is a device that continuously draws fuel from the fuel tank and delivers it at a specified and specified flow rate. Based on the function of the fuel pump armature, its performance directly affects the performance of the engine. The fuel pump armature is the "heart" of the electronic fuel injection engine. There are two ways for the fuel pump armature to supply fuel. One is external, where the fuel pump is connected in series on the pipeline outside the fuel tank. The other is built-in, where the fuel pump is installed in the fuel tank and immersed in gasoline, so the fuel pump is easy to heat up, has low noise, and has a long service life, so it is widely used. In the fuel, the electric fuel pump is responsible for supplying a certain amount of fuel, and its unit fuel consumption is more than 8 times between the rated power operating conditions of the engine. A large amount of fuel continuously returns to the fuel tank through the fuel pressure regulator, which controls the fuel pressure and cools the fuel line to avoid air blockage. Functions of the fuel pump armature: 1. The main components of the fuel pump armature motor include a permanent magnet fixed on the body and an armature reaction that generates an electromagnetic torque, as well as a brush device installed on the body. The brush contacts the armature on the commutator; Connect the wires to the outside of the terminal, wind the armature of the pressure-controlled fuel pump armature, rivet the coil on the outside of the fuel pump armature, and assemble the components into a non-dismountable unit.
