Rotor Assembly

In today’s rapidly – developing automotive industry, the power system of a vehicle is like its heart, and the Rotor Assembly is an indispensable and crucial component within this heart.

Ingenious Structure, Shouldering the Mission of Power Transmission

The automotive Rotor Assembly is mainly composed of key parts such as the iron core, winding, commutator, and shaft. The iron core is made by laminating high – permeability premium silicon steel sheets. This structural design effectively reduces hysteresis and eddy – current losses, enabling efficient conduction and concentration of the magnetic field, thus laying a solid foundation for the energy conversion of the motor. The winding is tightly wound around the iron core. When current passes through it, a powerful electromagnetic force is generated to drive the rotor to rotate. The commutator is connected to the winding. Through cooperation with the brushes, it accurately changes the direction of the current, ensuring that the rotor can rotate continuously and stably, thereby efficiently converting electrical energy into mechanical energy and providing strong power for the vehicle’s movement. The shaft is the supporting and power – output component of the entire Rotor Assembly. It has high strength and precision and can stably transmit torque to drive the vehicle’s transmission system.

High – quality Material Selection, Laying the Foundation for Excellent Performance

The quality of materials directly determines the performance and reliability of the Rotor Assembly. We carefully select high – quality raw materials and strictly control every production process. The silicon steel sheets used for the iron core have the characteristics of low iron loss and high magnetic flux density. While ensuring efficient magnetic – field conduction, they can effectively reduce energy losses and improve the efficiency of the motor. The winding uses high – purity copper wires. Their good electrical conductivity and flexibility ensure smooth current transmission, reduce resistance heating, and enhance the stability and durability of the Rotor Assembly. The commutator is made of materials with excellent wear – resistance and electrical conductivity, which can maintain good contact performance during frequent current commutation, reduce wear, and extend the service life. The shaft is made of high – strength alloy steel. Through special processing and heat – treatment processes, it has excellent strength, toughness, and fatigue – resistance, and can withstand various stresses under high – speed rotation and complex operating conditions, ensuring stable and reliable power transmission.

Precision Manufacturing, Ensuring Efficient and Stable Operation

The precision of the manufacturing process is an important criterion for measuring the quality of the Rotor Assembly. We use advanced automated production equipment and high – precision processing techniques to strictly control the entire production process of the Rotor Assembly. From the punching and laminating of silicon steel sheets, to the winding and welding of the winding, and then to the processing and assembly of the commutator and shaft, every step follows strict process standards and quality – control systems. By precisely controlling dimensional accuracy, geometric tolerances, and assembly clearances, we ensure that all components of the Rotor Assembly fit closely and operate smoothly. The produced Rotor Assembly features low vibration, low noise, and high efficiency, and can operate stably under various operating conditions of the vehicle, providing continuous and reliable power output for the vehicle.
