Bonded Ring NdFeB Magnet Description
Bonded NdFeB magnets, i.e. bonded neodymium iron boron magnets, are those permanent magnetic materials made of rapidly quenched NdFeB magnetic powders combined with resin binders (epoxy, Nylon/polyamide (PA), polyphenylene sulfide (PPS), etc). They are manufactured through a bonded process (compression, injection, extrusion or calendaring molding), so it is possible to obtain complex geometries with high dimensional precision. Controlling the performance and proportion of NdFeB magnetic powders, it can adjust the magnets' magnetic properties in a continuous range. Due to their complex geometries availability, high dimensional precision, uniform magnetic properties, diverse magnetization patterns, good corrosion resistance and mechanic properties, bonded NdFeB magnets are widely applied in spindle motors, micro-motors, direct current (DC) motors, synchronous motors, power tools, magnetic rollers, Hall effect sensors, etc.

Bonded Ring NdFeB Magnet Application
This specification product is used in floor scrubber motors. Floor scrubber motors mainly use the magnetic field and magnetic force generated by the current to drive the motor to rotate. By using transmission devices such as belts, gears, and chains, the motor's speed and torque are transmitted to equipment such as brushes or vacuum heads to achieve cleaning functions such as floor scrubbing or vacuuming. NdFeB magnets can also drive the motor to rotate by controlling the current to form a speed-regulating device. Users can adjust the motor speed according to specific cleaning requirements to meet different cleaning needs.

Safety Notes for the Application and Storage of Bonded Magnets
Do not place magnets near a person wearing electrical medical equipment, such as a pacemaker, because the magnet may result in a malfunction of the equipment and endanger a person's life.
Keep magnets away from magnetic memory media or other magnetic field-sensitive devices such as magnetic cards, tapes, floppy disks, hard disk drivers, and watches. Otherwise, information stored in the media or the devices may be damaged.
Big blocks of magnet will strongly attract each other or attract iron steel pieces, which may cause serious injuries to a person.
Relatively weak in strength, bonded magnets may break into pieces when collide with other materials. Be careful in assembling magnets and prevent fine fragments from entering into the eyes or causing other injuries.
Keep magnets in good condition and avoid the following environment in case the magnets become rust or weaken in mechanical or magnetic strength< With acid, alkali, organic solvent, or electrolytes.
