Fan motor magnets are magnets used inside fan motors, predominantly in arc shapes. Common types of fan motors utilizing hard magnets include industrial fan motors, DC fan motors, bladeless fan motors, automotive fan motors, and axial-flow fan motors. The primary magnet materials used are ceramic ferrite and neodymium iron boron, such as irregular wet-pressed ferrite magnets, sintered irregular ferrite multi-pole rings, sintered neodymium iron boron magnets, and bonded neodymium iron boron multi-pole rings.
Below is the mold dimension table for curved ferrite magnets used in our company's fan motors.
