Methods for winding the armature of a DC brushless automotive motor

　　Coil inductance DC brushless Automotive armature The method of winding is to leave a section of the cable end free and tie it tightly to the shaft. Hold the automotive armature with one hand, and with the other hand, wind the coil inductance clockwise. Taking a five-slot armature as an example, the first electromagnetic coil is 1-5, the second electromagnetic coil is 2-6, then 3-7... Gradually, the two 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, and the two sides of many components are on the top layer.

　　In order to ensure the insulation layer between the top layer and the next layer components, it is advisable to place 0.1-0.15mm thick insulating paperboard shims in between.

　　When the slot winding coil inductance reaches a certain level, a wire board is needed to make it reach the bottom of the deep 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 time. The wire may short-circuit due to partial stress. 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 automotive armature in DC brushless motors:

　　In a DC motor, when a DC regulated power supply is input, the armature winding is subjected to Ampere force in the magnetic field, generating a driving torque that drags the load to move, converting the input DC power into output mechanical energy. In a DC motor, under the drag of the transmission device, the armature winding cuts the magnetic lines of force in the magnetic field, generating an induced current. Under the action of the carbon brush rectifier, the input mechanical energy is converted into output DC power.

　　As we all know, the operation of the engine requires strong support from external forces, and the automotive starter plays this role. The automotive starter uses a DC motor to generate driving force, which is transmitted to the ring gear through the starter drive gear, driving the crankshaft and transmission shaft to rotate and start the engine. The armature of the automotive starter is the main component of the automotive starter. The armature plays an important and core role in the process of mutual conversion between mechanical energy and electromagnetic energy in the motor. For a generator set, this is the component that generates the induced electromotive force, such as the motor rotor in a DC motor, the motor stator in a DC motor. For a motor, this is the component that generates the magnetic force, such as the motor rotor in a DC motor. The armature is a component with wires in an electric motor, because the wires generate magnetically induced current in the wires due to the relative motion of the electromagnetic field between the magnetic pole pieces, or because the current passing through the wires generates an induced coil, making it rotate in this magnetic field. The armature is composed of electromagnetic coils wound according to a certain law and interconnected to achieve electromechanical energy conversion.

　　In the existing automotive armature assembly process, it is easy to cause poor coaxiality due to the long shaft, resulting in low matching accuracy between the gear and the load turbine, increased electromagnetic noise, shortened armature service life, and reduced motor operation stability. Some armature wire coil noses are small in size, resulting in heat accumulation, high temperature, and easy failure. Armature overheating and expansion can also lead to penetration, which cannot meet the current requirements for this product.
