Material and performance notes
Motor magnet selection balances torque density, temperature, demagnetization resistance, cost, and rotor construction. The best material depends on the motor duty cycle and available package space.
Sintered NdFeB supports high torque density and compact motors, while bonded or injection molded magnets can simplify ring shapes and multi-pole patterns.
Ferrite can be a good fit when cost stability matters and the motor design can accept a larger magnetic circuit.
Key performance inputs include air gap, rotor geometry, magnet temperature, reverse field exposure, retention method, and required efficiency.
