China Neodymium And Ferrite Magnets Manufacturer & Supplier 
The 130 DC motor is a very common small motor model widely used in products such as toys, fans, car models, electric toothbrushes, and small appliances. This type of motor typically employs two curved magnets (also known as motor magnets or pole pieces) to form the stator magnetic field. Below is a detailed introduction to the magnet dimensions and commonly used materials.
130 DC Motor Magnet Dimensions Overview;
While these magnets are primarily used in 130 DC motors, their dimensions may vary slightly. Common arc magnet specifications include: R9.6 × r6.9 × W14 × H13, R9.6 × r6.9 × W14 × H12 × t2.8, and (R10 - r8) × 14 × 13, where 14 represents the chord length and 13 denotes the height.
Regarding magnet materials, there are primarily two types: sintered neodymium-iron-boron magnets and sintered ferrite magnets. For high-performance applications, choose neodymium-iron-boron magnets, which offer high rotational speeds and enhanced torque. For cost-effective solutions, opt for ferrite magnets.

Regarding magnetization methods, the 130 motor magnets predominantly employ radial magnetization, with N and S poles distributed along the curved surface. Alternatively, two curved magnets can be assembled before magnetization to ensure magnetic field symmetry.
The above covers the specifications, dimensions, and materials of 130 DC motor magnets. For custom orders—including small magnets, large-sized magnets, or specialized magnets—please contact us for quotations and sample processing.
