Join the Movement for Energy Efficiency in India - Choose BLDC Ceiling Fan Magnets
Switch to Energy-Efficient BLDC Ceiling Fan Magnets for a Sustainable Future in India
Background of Switching to Permanent Magnet Motor
As India strives to improve energy efficiency and reduce its carbon footprint, many are turning to high-efficiency BLDC fan magnets as a smart and sustainable choice. These advanced motors use multipole ring magnet technology to deliver powerful and reliable performance while consuming less energy than traditional motor systems.
Introduction of Ceiling Fan Magnets
BLDC fan magnets can be bonded ferrite magnets with multipole (e.g. 16 poles inside) or sintered ferrite magnets in segment shape injected molded with plastic. Bonded ferrite magnets in ring shape are characterized by its good mechanical strength and easiness for installation and have gained popularity in many developing countries.
Magnetization Pattern of Ceiling Fan Magnets
These bonded multipole ring magnets are typically made from bonded ferrite magnet materials and are magnetized in multiple poles. The flux density in the inner diameter is directly related to both the number of poles and the thickness of the wall. Generally speaking, the more poles a fan magnet has, the higher its flux density will be. Similarly, increasing the wall thickness of the magnet will also lead to a higher flux density.
At Tengye Magnetic, we have the capability to manufacture bonded multipole ring magnets with skew magnetization. This type of magnetization can result in a smoother motion and reduced noise during motor operation, which can enhance the overall user experience.
Size and Dimension of Ceiling Fan Magnets
The most common size of these magnets is around OD152.4 x ID133.5 x H24. Any differences in the outer diameter (OD) and inner diameter (ID) of the magnets can cause installation problems. At Tengye Magnetic, we take the confidentiality of our customers’ molds very seriously, and we only use them for the specific customer’s project. To produce ceiling fan magnets, our customers are required to invest in molds, which can cost between 3500 and 6000 USD.
