Permanent magnet cores are widely used in industrial automation, automotive, medical, and electronic devices. In the automotive sector, permanent magnet cores are used in the drive motors of new energy vehicles to improve motor efficiency and reduce energy consumption. In the medical field, they are essential components of MRI equipment, providing critical support for medical diagnostics. Additionally, permanent magnet cores are used in various sensors and actuators to provide precise control for automated equipment.
Advantages of Permanent magnet motor cores
High efficiency: Precision laminations help reduce core loss and improve motor performance.
Compact design: Supports high torque and power density within limited installation space.
High accuracy: Consistent dimensions help maintain a stable stator-rotor air gap.
Custom structures: Available for PMSM, IPM and SPM motor designs.
Low noise and vibration: Controlled stamping and stacking improve operating stability.
Flexible assembly: Loose, interlocked, welded, bonded and interlock-free cores are available.
Prototype to mass production: Supports sample development, tooling, precision stamping and volume manufacturing.
