		HIRST’S RANGE OF MAGNETISERS

Introduction

Hirst Magnetic Instruments Ltd. design and manufactures magnetising systems capable of magnetising permanent magnets and assemblies containing permanent magnets.

Hirst’s range of easy to operate magnetising systems offers flexibility and control at both high and low production rates. They can be operated as  stand-alone systems, integrated with other Hirst Magnetic Instruments Ltd.  products or integrated with customer’s external equipment.

Models are available in each range suitable for magnetising any suitable material including:

• NdFeB - Neodymium Iron Boron
• Sm2Co17 -Samarium Cobalt 2-17
• SmCo5 - Samarium Cobalt 1-5
• Strontium Ferrite
• Barium Ferrite
• Alnico/Alcomax
• All other permanent magnet materials

Hirst Magnetic Instruments Ltd.  has developed a series of magnetisers that support a variety of applications, a selection of which is indicated below:

• Saturation of permanent magnet and magnet assemblies
• Magnetising sub assemblies containing the magnet which avoids contamination
• Laboratory work where magnet development is undertaken
• Multi-pole magnetising of rare earth magnets
• Manufacture of permanent magnet motors or voice coil motors
• Servicing areas such as motor repairs

MAGNET CHARACTERISATION

INTRODUCTION OPEN + CLOSE MAGNETIC CIRCUIT EDDY CURRENTS COMPARISON OF TECHNOLOGY USED IN MEASURING MAGNET CHARACTERISTICS

Introduction

The purpose of a magnetic characterising system is to determine the magnetic properties of a magnet or magnetic material.  This information can be used for testing batches of all magnets in production, quality issues and research purposes.

The principles behind the technologies can be described as:-
“By applying a known magnetic field to a magnetic specimen, the applied field strength is monitoring against the specimen’s own magnetism (total flux) with the resultant changes being recorded for analysis”.

The magnetic characteristic is obtained by analysing the applied magnetic field and the sample’s own magnetism.

Although the principles are simple, it is the method of generating the applied field and measuring the magnets “magnetism” that differentiate between the various methods of measurement available, along with the limits to data available and the range each system can operate over.

Magnet characterising technologies include:

• Pulsed Field Magnetometry (PFM)
• Vibrating Sample Magnetometry (VSM)
• Permeameter technology (Hysteresograph or permeagraph)

Before describing the above technologies in more depth, consideration needs to be given to two important factors in choosing a magnetic characterising technology namely, Open and Closed Magnetic Circuit Effect and Eddy Currents.

DEMAGNETISERS

INTRODUCTION PRINCIPLES OF DEMAGNETISATION TYPES OF DEMAGNETISING SYSTEMS MECHANICAL HANDLING

Introduction

Hirst Magnetic Instruments Ltd. design and manufacture demagnetising systems capable of reducing the existing flux in magnets, ferrous material, magnet housings and equipment.

Hirst’s range of easy to use demagnetising systems offers flexibility and control at both high and low production rates. They can be supplied for manual operation, with suitable PLC interface controls or integrated with other Hirst products.

Models are available in each range suitable for demagnetising permanent magnets or ferrous material.

Demagnetising materials, (or degaussing or deperming as it is also known), plays a vital role in the flow of work of many industrial processes around the world.

Components may become magnetised as part of the production process or are supplied magnetised (intentionally or otherwise). They often need to be demagnetised to avoid production problems, to make handling easier or to recycle components.

It is therefore necessary to remove, or greatly reduce this unwanted magnetism.
