Ferrite segment magnets provide moderate magnetic force and are extremely stable under thermal and chemical stress. Their shape is specifically designed for radial magnetic applications, offering efficient flux distribution in motor assemblies.
Why choose Ferrite Segment Magnet
● Motor-optimized design: The arc shape fits perfectly into circular stator structures, maximizing magnetic efficiency.
● Durability: Highly resistant to demagnetization and corrosion without the need for coating.
● Thermal stability: Operates effectively under high-temperature conditions.
● Cost-efficient production: Ideal for mass production due to low raw material and processing costs.
● Reliable for long-term use: Ferrite material ensures performance longevity with minimal degradation.
Application:
Ferrite segment magnets are mainly used in permanent magnet DC motors, washing machine motors, ceiling fans, and motorcycle starter motors. Their arc structure allows them to form a consistent magnetic field inside circular motor housings, making them an essential component in motor-driven systems with moderate power requirements.
