The automotive armature is one of the core components of an automotive motor, playing a crucial role in the entire automotive electric system. As a company providing manufacturing services for a variety of automotive motor armatures, we are committed to providing high-quality armature solutions for automotive and motor manufacturers.

In automotive motors, the armature is the key component that converts electrical energy into mechanical energy. It consists of many windings that, through interaction with a magnetic field, generate force and motion. Therefore, the design and manufacturing quality of the armature directly affect the performance and efficiency of the motor.

Our company possesses advanced manufacturing equipment and a technical team capable of customizing various types and specifications of automotive armature products according to customer requirements and needs. Whether it's a DC motor or an AC motor, we can provide high-performance armature solutions. Our products are widely used in various vehicle types, including automobiles, motorcycles, and electric bicycles.

In the manufacturing process of automotive armatures, we strictly control each link to ensure product quality and reliability. We use high-quality materials and advanced production processes to ensure that the armatures have good thermal stability, wear resistance, and corrosion resistance. At the same time, we also conduct rigorous quality inspections and testing to ensure that each armature meets industry standards and customer requirements.

In addition to providing high-quality armature products, we also provide technical support and after-sales service. Our professional team can provide armature design consulting, technical training, and troubleshooting services to help customers solve various armature-related problems.

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 function of a DC motor armature

The armature is a crucial component in an electric motor, playing a central role in the conversion between mechanical and electromagnetic energy. In a generator, it is the component that generates the electromotive force, such as the rotor in a DC motor and the stator in a DC motor. In a motor, it is the component that produces the magnetic force, such as the rotor in a DC motor. The armature is the component in an electric motor that contains the coils, which move relative to the electromagnetic field. In a generator, the rotation of the coils generates an induced current, producing electricity. In a motor, the energized coils are subjected to Ampere's force in the magnetic field, causing rotation. A DC motor or related equipment can be described from either a mechanical or electrical perspective. Although distinctly separate, these two terminologies are often used interchangeably or in combination. This can lead to confusion when using hybrid devices such as brushless DC motors or when communicating between personnel accustomed to different equipment configurations. In most generators, the field magnet rotates and is part of the rotor, while the armature is stationary and part of the stator.

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...
