  I believe everyone knows that in the process of converting mechanical energy and electrical energy in a fuel pump, this component plays a key and pivotal role. For a generator, it is the component that generates electromotive force. Let me explain below. Fuel pump armature What are the advantages?

  The fuel pump armature is now the part of the motor that houses the coil, and the relative movement of the coil and the magnetic field. Actually, it is mainly a coil group, wound and connected according to certain rules. It is one of the main components in the electric motor that realizes the conversion of electromechanical energy. The fuel pump armature is composed of single-turn or multi-turn coils, and each turn can also be wound with multiple parallel wires. It shows a coil placed in the slot. In particular, it should be able to generate sufficient induced electromotive force and allow a certain armature current to pass through, thereby generating the required electromagnetic torque and electromagnetic power. In addition, it should save non-ferrous metals and insulating materials. Of course, its structure is simple and reliable. Moreover, the fuel pump armature is composed of many coils (hereinafter referred to as components) connected according to certain rules. It is wound with high-strength enamelled wire or glass fiber-wrapped flat copper wire. It should be known that the coil sides of some different coils are embedded in the armature in two layers. Proper insulation must be provided between the iron core and the upper and lower coil sides in the slot. In order to prevent the centrifugal force from throwing the coil edges out of the slot, the slot is fixed with a slot wedge.

  The fuel pump armature is a component in the motor with a coil. If it moves relative to the magnetic field during use, it generates an induced electromotive force, and then it will generate electricity by rotating under force. In an electric motor, when energized, it can also be subjected to Ampere force in the magnetic field, causing it to rotate in the middle. Some more important points are that it exists relative to the magnetic pole. The fuel pump armature and the magnetic pole are two main components of synchronous motors and DC motors, so this is also the part generated at this time. The armature is the induced electromotive force. The part that passes current and generates electromagnetic torque is composed of an iron core and corresponding windings. As a manufacturer, we specialize in the design, manufacturing, and operation of automotive motor armatures and stators and rotors. Our main products are automotive starter armatures, fuel pump armatures, P-gear armatures, and hydraulic lifting DC motor armatures.

Methods for winding the armature of a DC brushless automotive motor

The method for winding the armature winding of a DC brushless car motor is to leave a section of the cable end free and tie it tightly to the shaft. Hold the car armature with one hand, and wind the coil inductance clockwise with the other hand. Taking a five-slot armature as an example, the first coil is 1-5, the second coil is 2-6, then 3-7..., and so on. The sides of many components are on the next layer. The 5-9 components have one side on the next layer and the other side on the top layer. The sides of many components are on the top layer. In order to ensure the insulation between the top layer and the next layer components, it is advisable to place 0.1-0.15mm thick insulating paper pads in between. When the coil inductance in the slot reaches a certain level, a crossbar is needed to make it reach the bottom of the slot. When winding the coil inductance, the wire should be tightened first. Whether in the slot or the wire connection part, it is necessary to prevent the occurrence of crossed turns to prevent excessive space occupation and short circuit between turns due to partial stress of the wire. After all the windings are wound, the wire ends of the same winding component are bundled together, then the insulation layer of the wire connector is removed, different color waterproof sleeves are used, and they are embedded in the corresponding commutator segments. The important role of the armature in a DC brushless motor: DC motor,

Design rules for automotive armatures

Automotive armature manufacturers indicate that single-layer windings are not suitable for large-capacity motors, and small-capacity motors should not be double-layered. The magnetic flux density of the motor core should not be too high or too low. When the frequency and thickness of the silicon steel sheet core material are constant, the iron loss depends on the magnetic flux density. If the magnetic flux density is too high, the iron loss increases, and the motor efficiency decreases. The increased heat from the iron core increases the motor temperature, and the increased excitation power increases the motor power factor, so the magnetic flux density of the core should not be too high. Try to avoid excessive saturation of the magnetization curve. If the magnetic density is too low, it will increase the amount of motor material used, increasing the cost. The rotor teeth are narrow, the magnetic density is high, the slot entry wire is large, that is, the automotive armature slots are large. Automotive armature manufacturers indicate that due to poor air conduction, there are many gaps in the slots, affecting the coils and easily damaging the heat dissipation of the insulation material, accelerating the increase in motor temperature. The slot fill factor of the motor slots cannot be too high or too low. Usually, the slot fill factor for low-speed motors is 75% to 85%, which can effectively prevent the enamelled wire from loosening in the slots. The design of the motor rotor slot shape should use parallel trapezoidal recesses as much as possible, and the edges of the recesses should not have sharp corners. Try to use a circular bottom recess, because the circular slot is filled with aluminum, which is easy to injection mold and the stator chip is easy to insert. The coil current density should not be...
