He magnets are used in a variety of industries, industrialequipments and products. They can be produced by different magnetic materials such as NdFeB, ferrite, SmCo and Alnico material. Furthermore, industrialmagnets can be? magnetic assemblies?which consist of magnet and some other partslike metal, plastic, nylon and etc. The main applications are all kind ofmotors, stators, rotors, generators, engines, couplings, lifters, separators,filters, tools, electric vehicles and so on.
Typical Application Case
The four kinds of permanentmagnets can all be used as industrial magnets. Owing to their differentfeatures and performance, they are applied in different industrial products.For example, neodymium iron boron magnets and ferrite magnets are mostly usedfor motors and generators. The maximum operating temperature of Alnico magnetsis up to 550~600℃, they are universally used in various kinds of industrialinstruments and meters. Compared to NdFeB magnets, SmCo magnets are moresuitable working in high temperature environment. Besides, SmCo permanent magnets are very strong inresistance of corrosion and oxidation. Therefore they are widely used innational defense industry, military industry, microwave devices, sensor,magnetic gear, magnetic processor and electrical machine.
Permanent magnet AC servo motor, alsoknown as permanent magnet synchronous servo motor, uses high energyNeodymium-Iron-Boron permanent magnets to provide air gap magnetic field. Thismotor embodies the patented surface magnet assembly technology, whichendows the motors with the highest torque density and compact size.
Servo motor as a rotor is apermanent magnet, the drive control of the U / V / W three-phase power, anelectromagnetic field, the rotor is rotated under the action of this magneticfield, and the motor comes encoder feedback signal to the drive, the driveaccording to the feedback value and the target value, adjusting the angle ofrotation of the rotor. It depends on the precision of the servo motor encoderaccuracy (number of lines).
AC servo brushless motor is alsodivided into synchronous and asynchronous motors, motion control in general arecurrently using synchronous motors, large power range it can do a lot of power.Large inertia, the maximum rotational speed is low, and with the powerincreases rapidly decreased. Thus suitable for low speed applications runningsmoothly.
Linear Motors are mostly used inautomatic control system, long time-running driving motors and machines thatrequire large linear power in a short time and within shortdistance. Permanent magnetic linear motor magnet track, whichreplaces traditional secondary coil, can generate smooth and stablemagnetic force although applied voltage fluctuation. It hasmerits of simple structure, non-contacting, non-wearing, low noise,quick speed, high positioning precision and flexible assembly。
Some of its applications are:

--- Automatic monitoring and feedingsystem
--- Battery sorting system
