电驱动产品12.jpg
A key assembly component. It utilizes the interference fit between the ring and the shaft to compress the rotor laminations, thereby ensuring the stability and reliability of the rotor structure. This design not only helps to enhance the overall performance of the motor but also improves the durability of the motor to a certain extent, making it an indispensable part of the electric drive system in new energy vehicles.

Product advantages

  • Structural stability: The rotor interference pressure ring compresses the rotor laminations through interference fit, ensuring the stability of the rotor structure. Under high-speed rotation and complex working conditions, the rotor can maintain a stable shape, making it less prone to deformation or loosening, thereby improving the operational reliability and durability of the motor.
  • Improving transmission efficiency: Interference fit can reduce the gaps between rotor laminations, decreasing friction and energy loss caused by these gaps. This helps to enhance the transmission efficiency of the motor, allowing the electric drive system to convert electrical energy into mechanical energy more efficiently, thus improving the range and power performance of new energy vehicles.
  • Simplifying assembly process: The design of the rotor interference pressure ring simplifies the assembly process of the rotor. Compared to other connection methods, interference fit does not require additional fasteners or adhesives, reducing assembly difficulty and costs. At the same time, this integrated design also helps to minimize performance issues caused by assembly errors.
  • Strong adaptability: The rotor interference pressure ring is suitable for various types of electric drive systems in new energy vehicles, including permanent magnet synchronous motors, AC asynchronous motors, etc. Its compact structure and high reliability can meet the needs of different vehicle models and working conditions.
  • Enhancing safety: In new energy vehicles, the safety of the electric drive system is crucial. The rotor interference pressure ring reduces safety risks caused by rotor failures by ensuring the stability of the rotor structure. Additionally, its integrated design helps to minimize safety hazards due to loosening or detachment.
