N35 vs N42
Compare N35 and N42 at 20°C, then assess the actual material at the intended operating point.
N48 vs N52
N48 vs N52
Compare N48 and N52 at 20°C, then assess the actual material at the intended operating point.
N42 vs N42SH
N42 vs N42SH
Compare N42 and N42SH at 20°C, then assess the actual material at the intended operating point.
N45SH vs N48SH
N45SH vs N48SH
Compare N45SH and N48SH at 20°C, then assess the actual material at the intended operating point.
N42H vs N42SH
N42H vs N42SH
Compare N42H and N42SH at 20°C, then assess the actual material at the intended operating point.
Material Comparisons
Compare magnet materials: NdFeB, SmCo, and NdFeB variants (sintered, bonded).
NdFeB vs SmCo
NdFeB (Neodymium) vs SmCo (Samarium-Cobalt)
Compare the actual NdFeB and SmCo grades at operating temperature, including field, stability and corrosion requirements.
Sintered NdFeB vs Bonded NdFeB
Sintered NdFeB vs Bonded NdFeB
Sintered and polymer-bonded NdFeB use different production routes. Bonded properties depend on powder, alignment, binder and molding process.
NdFeB vs Ferrite
NdFeB (Neodymium) vs Ferrite (Ceramic)
Compare NdFeB and ferrite using field requirements, temperature and the available geometry.
GBD vs Bulk Alloyed NdFeB
Grain Boundary Diffusion (GBD) vs Bulk Alloyed NdFeB
GBD adds a diffusion treatment to a sintered magnet. Compare the measured properties, composition and process route for the actual geometry.
Coating Comparisons
Compare NdFeB coating systems on corrosion resistance, durability, and cost.
NiCuNi vs Epoxy
NiCuNi Coating vs Epoxy Coating
NiCuNi is a metal plating stack; epoxy is a polymer coating that may be applied over a specified base layer.
Epoxy vs Zinc
Epoxy Coating vs Zinc Coating
Compare the specified epoxy or zinc coating system against the environment, assembly process and finished dimensions.
Architecture Comparisons
Compare magnet architectures: radial multi-pole rings, arc segments, and alternatives.
Radial Multi-pole vs Arc Segment
Radial Multi-pole Ring vs Arc Segment Assembly
A radial ring has one magnetic body; a segmented rotor uses separate magnets. Compare the waveform and assembly in the actual motor.
Interior PM vs Surface PM
Interior PM (IPM) Rotor vs Surface PM (SPM) Rotor
IPM places magnets inside the rotor; SPM places them at its surface. The complete motor design determines torque, speed range and demagnetization margin.
Sourcing Comparisons
Compare supply-chain strategies: factory-direct vs trading, geographic sourcing options.
Factory Direct vs Trading Company
Factory Direct Supplier vs Trading Company
Compare the contracting route, access to production records and responsibility for the order.
China vs Japan NdFeB Suppliers
Chinese NdFeB Supplier vs Japanese NdFeB Supplier
Qualify the actual production site and part offer. Country alone cannot establish quality, price or delivery.
Certification Comparisons
Compare quality management system standards relevant to magnet supplier qualification.
