Why Ferrite Magnets Are Widely Adopted in Global Industrial Production

Arc segment magnets are also known as curved magnets, segmented permanent magnets, motor ferrite segments, with different names used by different customers, yet they refer to the same product. They are mainly applied in motors, bonded to the inner surface of motor housings with adhesive. Many customers have raised the question: Which sides are the N pole and S pole of arc segment magnets? We will explain this in detail below. The N and S pole surfaces of arc segment magnets depend mainly on the magnetizing method customized by customers. Most motor clients require paired magnetization for arc segment magnets: two magnets form a pair. One magnet has the N pole on its outer arc surface and the S pole on the inner arc surface, while the other one features the S pole on the outer arc surface and the N pole on the inner arc surface. Manufacturers usually mark lines on the magnets with white marker pens to help customers quickly distinguish N poles from S poles and avoid assembly mistakes.

We produce magnets through one-step forming followed by precision grinding. The main custom machining processes for special-shaped ferrite magnets include edge cutting, corner chamfering, slotting and multi-hole drilling. Common special-shaped ferrite magnets include triangular, U-shaped, beveled, slotted round, slotted square, semicircular, racetrack and so on.

The axial flux motor sector is booming across automotive systems, home appliances and light electric vehicles. A hot debate among motor R&D engineers right now: Can anisotropic ferrite magnets substitute rare-earth NdFeB for flat axial flux rotors? The answer is clear: Absolutely viable for nearly all medium & low-speed mass-volume axial flux projects. Why fan-shaped ferrite segments are a perfect match for disc-type axial flux rotors Eliminate rare-earth supply risks & cut material costs drastically Volatile rare-earth pricing and unstable global supply chains have long plagued motor OEMs. Anisotropic ferrite slashes magnet material expenditure by over 60% while securing steady raw material supply, making it the cost-effective pick for mass-manufactured auxiliary drives. Fan-shaped segment geometry optimizes disc rotor magnetic circuits Our fan-shaped segmented tiles deliver uniform magnetic flux distribution across flat rotors. Backed by our mature wet-pressing forming process, ferrite segments effectively resist cracking during high-volume manufacturing. The slim profile also reduces overall rotor weight, maximizing the core strengths of axial flux motors: compact footprint and lightweight structure. Compliant with mainstream commercial application standards Our rare-earth-free ferrite axial flux solutions reach IE4/IE5 high-efficiency grades, fully satisfying the performance demands of: ▫️ Automotive auxiliary axial flux water pumps & cooling fans ▫️ Flat BLDC motors for household appliances ▫️ Industrial circulation pumps and HVAC fan drive units ▫️ In-wheel axial flux motors for light two-wheelers Open discussion for all motor engineers What is your most challenging technical hurdle when designing rare-earth-free axial flux motors? Is it magnet breakage, magnetic flux tuning, or tight rotor assembly tolerances?
