The importance of brushless motor stators and rotors in automotive parts manufacturing

In automotive parts manufacturing, the brushless motor stator and rotor are a very important component. It has many advantages, such as high efficiency, low noise, and long life. This article will discuss the importance of brushless motor stators and rotors in automotive parts manufacturing and explain why it is widely used in the automotive industry.

First, let's understand what a brushless motor stator and rotor are. The brushless motor stator and rotor are the core components of a brushless motor, consisting of a stator and a rotor. The stator is the stationary part, while the rotor is the rotating part. The brushless motor converts electrical energy into mechanical energy through the action of a magnetic field, thereby driving the operation of various parts of the vehicle.

An important advantage of the brushless motor stator and rotor is its high efficiency. Compared to traditional brushed motors, brushless motors are more efficient. This is because brushless motors do not have brushes and commutators on the rotor, reducing energy loss. Due to its high efficiency, the brushless motor can provide more powerful power output, making the vehicle more stable and faster during driving.

Secondly, the brushless motor stator and rotor are characterized by low noise. Because brushless motors do not have the friction and noise of brushes and commutators, their operation is very quiet. This is very important for improving driving comfort and passenger experience. In the case of urban traffic congestion, passengers can enjoy a quieter riding environment.

In addition, the brushless motor stator and rotor also has a long lifespan. Traditional brushed motors have a shorter lifespan due to brush wear and the need for brush replacement. Brushless motors, however, have a longer lifespan due to the absence of these wear parts. This makes brushless motors very popular in automotive manufacturing because they can reduce maintenance costs and the frequency of parts replacement.

In summary, the importance of brushless motor stators and rotors in automotive parts manufacturing cannot be ignored. Their advantages of high efficiency, low noise, and long life make them an indispensable key component of the automotive industry. By using brushless motor stators and rotors, automakers can produce higher quality, more reliable, and more competitive automotive products.

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.

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...
