CEILING FAN MAGNETS
High Performance Bonded Ferrite Ring Magnets
The ceiling fan magnet is a high-performance magnet specially designed for fans. It is mainly utilized to improve the efficiency and stability of the fan. It maximizes the motor’s performance, raising the fan blade rotational torque and enabling the fan to maintain excellent airflow with reduced power consumption. It fits household and business environments.
Ceiling fan Magnets in Standard Sizes & Custom Options
The magnetic ring’s performance and stability depend significantly on its size, which directly influences a ceiling fan’s running efficiency, stability, and service lifetime. This is shown in the following:
Inner Diameter: The correct installation of the magnetic ring on the motor shaft depends on its inner diameter. An insecure fit between the magnetic ring and the motor shaft resulting from either too big or too small an inner diameter might produce looseness or unequal pressure, therefore influencing the magnetic field distribution. The outcomes are unstable fan speed, more motor load, and more energy use and noise.
Tolerance Precision: The magnetic ring’s fit to the motor shaft is directly influenced by its tolerance accuracy. Small tolerances guarantee a tight fit, reducing vibration and noise and improving stability. Greater tolerances cause the magnetic ring to move, producing an unequal magnetic force that could compromise the ceiling fan’s smooth running.
- The outer diameter (OD) typically ranges from 52.00 mm to 181.00 mm (2.05″ to 7.13″).
- The inner diameter (ID) ranges from 12.00 mm to 133.60 mm (0.47″ to 5.26″).
- The height (H) ranges from 12.00 mm to 25.00 mm (0.47″ to 0.98″).
- Magnetic properties range from 1650 GS to 2250 GS
TOPMAG covers all expenses connected with existing moulds and offers ready-made solutions to help decrease the initial investment in product development. We have over 100 standard ceiling fan magnet moulds, covering most of the market’s usual criteria. You will not incur additional mould costs if your ceiling fan magnet specification matches our current mould. This significantly lowers further product development costs and increases time to market.
*More significantly, we place a high value on the secrecy of client moulds, with each unique mould serving just the customer’s specific project to secure the exclusivity of ideas and products.
Grade of Ceiling Fan Magnets
From performance to cost, the choice of polymer matrix is crucial in manufacturing a BLDC fan motor. Typical forms of magnetic powders include FA11, FA15, FA19, FA20T, and FA22T. We usually advise using at least FA19-grade magnetic powder for such uses as it has the required thermal stability and can withstand high temperatures for significant times. FA20T or FA22T-grade magnetic rings, which offer outstanding thermal stability and improved magnetic performance and coercivity, are advised for applications demanding more. A more thorough specification table is below.

The Types of Ceiling Fan Magnets
Our latest magnet design features plastic injection-molded rings. In this process, ferrite magnetic powder is blended with thermoplastic binders at high temperatures and then molded into rings with pre-set magnetic poles. This embedded design simplifies the motor assembly and enables an integrated rotor design.
Additionally, we offer sintered ferrite rings assembled from precisely sized sintered ferrite segments using adhesives to form a complete ring with a continuous magnetic circuit. These sintered ferrite rings provide superior performance, with higher operating temperatures and magnetic properties than injection-molded rings.
