The Application of Ferrite Permanent Magnets in Automobile Industry

Sichuan Xinheng Magnetic Materials Co., Ltd. produces ferrite permanent magnets for different applications, among which sintered ferrite arc segment for automobile motors have become the main products.

Ceramic ferrite permanent magnets play a crucial role in the automotive industry, particularly in various electrical and electronic components of modern vehicles. Here's a brief introduction to the role of permanent magnets in automobiles:

1. Electric Vehicle (EV) Propulsion Systems: Permanent magnet ferrites are widely used in electric vehicle propulsion systems. They are employed in the permanent magnet motors that drive the wheels of electric and hybrid vehicles. These motors require high-performance magnets to generate the necessary torque and power. Ferrite magnets offer excellent magnetic properties, high coercivity, and good thermal stability, making them suitable for these demanding applications.

• Electric Power Steering (EPS): Permanent magnet ferrites find application in electric power steering systems, which have become increasingly common in modern vehicles. These systems use a motor to assist steering, and ferrite magnets provide the required magnetic field strength for the motor's operation. Ferrite magnets offer cost-effectiveness, reliable performance, and good temperature stability, making them a popular choice for EPS applications.

• Starter Motors: Permanent magnet ferrites are utilized in starter motors, which are responsible for initiating the engine's combustion process in internal combustion engine vehicles. The magnets in the starter motor provide the necessary torque to crank the engine and start the vehicle. Ferrite magnets offer a balance of performance and cost-effectiveness, making them suitable for starter motor applications.

• Electric Window Regulators: Permanent magnet ferrites are used in electric window regulator systems found in modern automobiles. These systems allow for automatic or manual control of the vehicle's windows. Ferrite magnets provide the required magnetic force to move the window regulator mechanism, enabling smooth and reliable window operation.

• Electric Door Locks: Permanent magnet ferrites find application in electric door lock systems. These systems enable centralized locking and unlocking of the vehicle's doors. Ferrite magnets offer the necessary magnetic force to actuate the locking mechanisms, ensuring secure and convenient access to the vehicle.

6.Brake Systems: Permanent magnet ferrites are also used in certain types of brake systems, such as regenerative braking systems found in hybrid and electric vehicles. These magnets assist in generating the necessary magnetic fields to enable energy recovery and provide braking force.

The role of permanent magnet ferrites in automobiles is essential for various electrical and electronic components, ranging from propulsion systems in electric vehicles to power steering, window regulators, door locks, and braking systems. Their reliable performance, cost-effectiveness, and magnetic properties make them suitable for these demanding automotive applications.
