Products Details
Custom Inner Outer Rotor Magnets is a core motor component we have been producing in our factory for many years. We carefully select high-performance neodymium magnets and assemble them into precise inner or outer rotor structures according to customer drawings, helping motors achieve higher efficiency, smoother operation, and better torque output.
Our team focuses on accurate magnet positioning, consistent magnetic strength, and reliable bonding or mechanical fixing methods. Many motor manufacturers procure Custom Inner Outer Rotor Magnets from us because we can support both prototype development and mass production. When you order this product, we work closely with your engineering team to match the magnetic circuit, air gap, and operating temperature requirements of your specific motor design.

Magnetic Circuit Matching Experience
Through years of cooperation with motor producers, we have learned that the success of a rotor largely depends on how well the magnets match the stator and overall magnetic circuit. We use simulation feedback and real motor testing data to fine-tune magnet grade, thickness, and magnetization direction. This practical approach helps reduce demagnetization risk and improves the final motor performance under continuous load.
