Bonded NdFeB Magnets and Assemblies

Bonded NdFeb is a kind of magnetic material which contains binder and takes NdFeB alloy as main component.Bonded Neodymium-Iron boron generally includes two types: molding (thermo-hardening resin binder) and injection molding (thermo-plastic resin binder).The company has been engaged in the production and manufacturing of rare earth permanent magnets since 1989, and has accumulated 30 years of experience to provide customers with reasonable magnetic field simulation and design suggestions, and cooperate with customers to participate in the troubleshooting of Brushless DC motor.

Features

High-quality raw material supply, high-precision equipment and automation equipment testing, combining the work of senior engineers in magnetic materials research, so that each magnet is in line with the specifications of the customer drawings.With many years of experience with? brushless DC, stepper motor professional manufacturers, in the solution of motor balance problems, static torque problems, motor ultra-high-speed applications and special environment applications have rich achievements, the magnet made by Highmag has the characteristics of high dimensional accuracy, stable performance and good one-time performance.

Typical Applications

Bonded NdFeb magnets are usually used as a micro-motor? stator or rotor it’s magnetized and interacts with the winding coil to form a driving unit.Digital cameras in consumer electronics, camcorders;TV, DVD player, computer, server;Office automation printing, duplicator;No-box refrigerators, air conditioners, microwave ovens, coffee machines, hair dryers, etc.Base station with 5G communication;A fascial gun for exercise and fitness;Dental washers, disinfectant sprays and surgical saws for medical equipment;Automobile seats, sunroof, steering system, tail box, rearview mirror storage and other aspects have been widely used, especially in the national promotion of energy saving, fast and efficient today, brushless DC motor and its core parts (bonded Neodymium iron boron magnet) more indispensable change.
