permanent magnet materials have been extensively used in various fields,and their applications are expected to widen in the futher.permanent magnets mainly consist of AINiCo,Ferrite and rare-earth.Permanent magnets find their applications in automobile industry,acoustic instrument speakers,microphones,home electric appliances,magnetic sensor,small motors for business machines such as brushless motors and stepper motors in computers,scanners,CD-ROM,and DVD.

In order to establish the desired magnetic fields in a permanent material,it is necessary to build a magnetic field of a fixed intensity and magnetize the material up to the saturation point of the maximum magnetic flux density.To this purpose,a high-capacity power source for producing magnetic fileds,magnetizing coils,and fixtures are needed.

Harbin Xianda Electron Co.,Ltd.(DCD)has already done tremendous research and development in this field.Our products have been widely accepted and appreciated by customers both at home and abroad.Our magnetizer&demagnetizer and coils can provide the best performance in high coercive force magnets,axially and radially multi-pole magnetization and fast,constant magnetizing.The lately produced intelligent definedvalue magnetizer&demagnetizer can meet customers'requirements,such as high uniformity,magnetizing/demagnetizing/reducing magnetism with arbitrary field intensity.

Long-life oil capacitors are adopted in all magnetizer.For different products and magnetizing requirements,we have a dozen specifications for selection.

• This magnetizer is most suitable for magnetizing Ferrite magnets,small and medium size ALNiCo magnets,rubber magnets,small rareearth magnets,small motors,and loudspeakers.The output voltage of the magnetizer is adjustable and it is error proof even at output short circuit conditions.

• This type is featured by its extremely short magnetizing current pulse width,and little heat generation in the magnetizing fixture.lt is most suitable for magnetizing multi-pole rare-earth(annulus multi-pole and plane multi-pole),motors and brushless motors.The magnetizer is error proof even at output short circuit conditions.

This type can be used both in magnetizing and demagnetizing permanent magnets simply by switching.This series of magnetizer/demagnetizer is used phase modulation technology and constant current charging.They are favorably suitable for magnetizing and demagnetizing magnets with high coercive force materials,such as rare-earth,motors,large loudspeakers and all magnet materials available today.

The magnetizer is error proof even at output short circuit conditions

This magnetizer is treated computer control and measure.lt has function of precise magnetizing,demagnetizing,and reducing magnetism with closed loop control for magnetic pieces,even though magnetic properties are very dispersion,after magnetized,they would be achieved completely uniformity.The precise control of magnetizing field intensity would reach enough uniformity with opened control.The residual magnetism of magnetic pieces would be less than 0.002T with the precise demagnetizing;the magnetizer is adopted combination for the operation sequence of magnetizing.demagnetizing,and screening,it is suitable for kinds of assembly lines.

The intelligent defined-value magnetizer/demagnetizer can follow your inclinations for products.

• This system,composed of magnetizer,computer test system and magnetization device,can completely meet the demands of on line magnetization and test for motor production line.The magnetic field and flux distribution test of motor magnet is finished in the process of magnetization.Meanwhile,the wave-form of magnetic field, strength of surface magnetic field, the max flux,the min flux and the average of flux will be displayed on the screen.

This machine can complete the automatic feed,magnetization and classification test.lt makes labour's complex work easier and avoids the unstable factor.lt's evident that this of machine has superiority in magnetizing multi-pole magnet.

The total process includes feed,magnetization,classification test,siving of the qualified/unqualified and sepration of magnets,which can be completed sequentially.With the help of PLC contral and pneumatic device, the operation is quick,simple and highefficient,This machine is fit for magnetization in batch.
