Cold Rolled Non-Grain Oriented Silicon Steel for new energy automobile motor(CRNGO for NEV)
Non-Oriented Silicon Steel (NOSS), also referred to as Cold Rolled Non-Grain Oriented silicon steel, plays a critical role in the performance and efficiency of electric motors used in new energy automobiles.
1. Electric Motor Stators and Rotors
The heart of any electric vehicle is its motor, where CRNGO plays a crucial role. The stator and rotor components of these motors require materials with excellent magnetic properties to ensure high efficiency and performance. CRNGO sheets are ideal due to their isotropic magnetic properties, which allow for uniform magnetic flux distribution, reducing core losses and enhancing motor efficiency.
2. Transformers
Onboard chargers and power electronics within NEVs often include transformers that convert electrical energy from one voltage level to another. CRNGO is utilized in transformer cores because it can handle high-frequency operations while minimizing hysteresis and eddy current losses, thus improving the overall efficiency of the charging system and power conversion units.
3. Inductors and Chokes
CRNGO is also applied in the construction of inductors and chokes, which are essential for filtering and stabilizing the electric currents in power electronic circuits. Its low core loss characteristics make it suitable for maintaining efficient operation at varying frequencies and load conditions.
4. Electromagnetic Compatibility (EMC) Shielding
In the compact environment of an NEV, electromagnetic interference (EMI) can be a significant issue. CRNGO can be used for shielding purposes around sensitive electronic components, protecting them from EMI while also confining the magnetic fields generated by the electric drive system within desired limits.
5. Battery Management Systems (BMS)
While not directly part of the propulsion system, BMSs play a critical role in monitoring and controlling the battery pack's performance. Components within BMSs may use CRNGO for certain magnetic elements or sensors that help monitor current flow, temperature, and other parameters vital to battery health and safety.
6. Auxiliary Motors and Actuators
Beyond the main propulsion motor, NEVs contain numerous auxiliary motors and actuators for functions such as air conditioning, window mechanisms, and steering systems. CRNGO can be found in the cores of these smaller motors, ensuring they operate efficiently and reliably over the vehicle's lifespan.
7. Wireless Charging Systems
As wireless charging technology advances, CRNGO finds application in the magnetic components of both the vehicle-mounted receiver and the ground-based transmitter. Its material properties support efficient wireless power transfer with minimal losses.
