The innovation of injection molded ferrite magnetic rings in the field of ceiling fans is mainly reflected in the improvement of motor efficiency, energy saving and noise reduction, and the enhancement of system reliability. The following are the key innovation points it brings:
1. Efficient and energy-saving motor system
-Injection molded ferrite magnetic rings are widely used in brushless DC motors (BLDC), which replace traditional AC induction motors in ceiling fans and significantly improve energy efficiency. For example,
Midea Industrial Technology’s “Ultra Efficient Ferrite Fan Motor System” achieves efficient operation across the entire area and significantly reduces energy consumption through the optimization of ferrite materials.
-The “Innovative Low Carbon Ceiling Fan” from the Industrial Technology Research Institute uses a permanent magnet brushless motor combined with ferrite technology, which consumes less than half of the power of traditional ceiling fans while maintaining high energy efficiency at low speeds,
Assist in achieving global energy conservation and carbon reduction goals.
2. Noise reduction and stability improvement
-The high-frequency impedance characteristics of ferrite magnetic rings can effectively suppress electromagnetic interference (EMI), reduce electromagnetic noise during motor operation, and make the ceiling fan run quieter.
-The injection molded ferrite rotor can improve the stability of the motor, reduce vibration and noise by optimizing the magnetic circuit design,
Suitable for high-end silent ceiling fans.
3. Lightweight and compact design
-The injection molding process makes the ferrite magnetic ring lighter and thinner, suitable for the compact design of ceiling fan motors. For example, the FT-170 series ferrite magnetic beads use surface mount technology to optimize
Space utilization rate, suitable for miniaturized ceiling fan motors.
-This design not only reduces the overall weight of the ceiling fan, but also lowers the inertia loss of the motor, further improving energy efficiency.
4. Long lifespan and low maintenance
-Ferrite materials are resistant to high temperatures and corrosion, and the injection molding process enhances the structural strength of the magnetic ring, allowing it to maintain stable performance even under long-term high-speed operation and reducing maintenance requirements.
-DC brushless motor paired with ferrite magnetic ring eliminates the problem of brush wear and has a much longer lifespan than traditional motors, making it particularly suitable for long-term use in commercial and household ceiling fans.
5. Intelligence and frequency conversion control
-The high-frequency characteristics of ferrite magnetic rings make them more suitable for variable frequency drive, and ceiling fans can achieve forward and reverse rotation functions through intelligent speed regulation (such as summer cooling and winter balanced heating), improving comfort.
-Midea Industrial Technology’s “high-efficiency hybrid magnetic circuit motor for compressors” technology also demonstrates the potential of ferrite in the field of frequency conversion, which can be applied to ceiling fan motors to achieve more accurate results
Speed control.
The injection molded ferrite magnetic ring has promoted the development of ceiling fans towards high efficiency, quietness, lightweight, and intelligence through material optimization and process innovation. In the future, with further breakthroughs in ferrite technology
The energy efficiency and user experience of ceiling fans will continue to improve, such as higher magnetic permeability and lower losses.
