The most promising application of motor magnets in the automotive industry（二）
Motor magnet tiles have various promising applications in the automotive industry, and some of the common ones include:
Fuel pump motor magnet
In traditional fuel vehicles, motor magnet tiles are the core component of the fuel pump motor, responsible for establishing a stable magnetic field to drive the pump core. These motors need to operate long-term in fuel media, so corrosion-resistant and stable magnet tiles are commonly used. With the development of new energy vehicles, the application of such magnet tiles is gradually shifting to electric coolant pumps, transmission oil pumps, etc., where requirements for high-temperature resistance and chemical corrosion resistance remain essential.
Heater motor magnet
In the heating systems of new energy vehicles, motor magnet tiles are crucial for reducing heating energy consumption. The motors driving blowers in PTC or heat pump systems are rapidly adopting high-efficiency BLDC motors, whose core relies on high-performance NdFeB magnet tiles. These magnet tiles ensure efficient motor operation in low-temperature environments, maximizing the conversion of electrical energy into warm air output. They play a vital role in minimizing winter range attenuation and improving energy efficiency.
Throttle motor magnet
Motor magnet tiles are used in electronic throttle valve motors to achieve precise control of engine air intake. This system demands extremely fast response and accurate positioning, making high-performance NdFeB magnet tiles the standard choice. The performance of the magnet tiles directly determines the throttle valve's opening/closing speed and control linearity, which is essential for improving engine combustion efficiency and meeting stringent emission regulations.
Exhaust valve motor magnet
In turbocharging systems, motor magnet tiles are used to drive wastegate actuators for precise boost pressure control. This application operates in extremely harsh conditions (high temperature, high-frequency vibration), requiring ultra-high temperature resistance and high coercivity NdFeB magnet tiles. These premium magnet tiles ensure stable actuator performance across all engine operating conditions, preventing demagnetization, and are key to achieving high engine performance and efficiency.
Electronic handbrake motor magnet
Motor magnet tiles are the core of the electronic parking brake (EPB) actuator motor, directly related to parking safety. This system requires the motor to provide substantial static holding torque and extremely high reliability, often utilizing highly stable, high magnetic energy product NdFeB magnet tiles. High-quality magnet tiles ensure instant locking and stable parking on extreme slopes and under varying temperatures, forming the foundation for advanced driver-assistance features like Auto Hold.
