Strong powerful radial ring magnet for motor
Radial Sintered NdFeB Ring Magnet is developed to meet different requirements of permanent magnet servo motor, using the new shaping method by multipole polymerization radial orientation.
Compared with segments jointed ring, radial ring magnet can improve the output characteristics and significantly reduce the loss of motor; it has excellent temperature stability, corrosion resistance and temporal stability, and so on, especially applying for high precision micro & special motor drive.
Features of GME radial ring magnet:
(1) The cylindrical shape enables higher precision in external dimensions.
(2)Can achieve uniform magnetic density flux distribution
(3) Fastening the magnet is simple, enabling assembly-related cost reductions
(4) Highly reliability due to enabling rotor construction from a single magnet
(5)Optional magnetization, including free multiple magnetizations, skew-type magnetization possible (Radial anisotropic magnet)
(6) Can obtain sine surface inductive flux distribution (multi-pole oriented magnet)
Advantages of GME radial ring magnet:
• Precision of geometry
• Variety of magnetic configuration
• Homogeneous distribution of magnetic field
• Design and assembly simplification
• Precision of motor performances
• Cost efficiency
• Huge marketing potential
Sizes and shapes of magnets can be customized:
• Maximum outside diameter is 60 mm
• Minimum inside diameter is 25 mm
• Maximum wall thickness is 7 mm
• Minimum wall thickness is 2 mm
• Maximum length is 25mm (for small thickness – 15)
• Tolerances: +/- 0.05 mm

Introduction of Great Magtech:
Advantages of GMEradial ring magnet
1. High Grade / High performance of radial ring magnet:
GME highest grade: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.
2. High Consistency of radial ring magnet:
The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67.
The consistency of the surface magnetic field and magnetic flux can be controlled at +/-1%.
3. High Working Temperature of radial ring magnet:
GME magnets can satisfy the working temperature requirements with excellent temperature resistance.
The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications.
