Major Difference Between Permanent Magnet & Electromagnet

Major Difference Between Permanent Magnet & Electromagnet The major difference between an permanent magnet and electromagnet is that the former can have a magnetic field when electric current flows through it and disappears when the flow of the current stops. On the other hand, a permanent magnets are made up of magnetic material that is [...]

  • The difference between electromagnet and permanent magnet

The difference between electromagnet and permanent magnet

The difference between electromagnet and permanent magnet Electromagnets (solenoids) is a kind of electromagnetic equipment, which transforms electric energy into magnetic energy, and then transforms magnetic energy into kinetic energy (electric energy → magnetic energy → kinetic energy). First of all, the core is wound with a conductive winding matching its power. Such a coil [...]

Magnets Technical Information

Magnets technical information The determining of magnetic properties is often not given its proper place along the development path of a product. These basic but important considerations are commonly considered as features which will adapt themselves into the required format at a later date. This may be true for applications using low coercive materials such [...]

Brief Introduction to Neodymium Magnet Materials

Brief Introduction to Neodymium Magnet Materials The third generation of rare earth permanent magnet, Neodymium Iron Boron (Neodymium magnets), is the most powerful permanent magnet in modern magnets. Neodymium Magnet Materials The highest Remanence (Br) of Neodymium magnet1 is 3.8 times that of ferrite magnet, 1.1 times of that of Aluminum Nickel cobalt [...]

How to Control the Quality of Neodymium Magnets?

How to Control the Quality of Neodymium Magnets? Permanent Neodymium magnet, chemically known as NdFeB, is known as the most significant magnet material with high performance and are widely applied in many industrial fields. To manufacture the highest quality magnet products, we need to assure the accuracy of: magnetic property, physical dimensions and surface plating. [...]

  • Wind Power Magnets

Wind Power Magnets

Wind Power Magnets To that end we have developed a line of permanent magnets exclusively for direct drive, wind power turbine generators. We have produced this grade of material for use in DD PMG's (Direct Drive Permanent Magnet Generators) for small and large size wind turbines from 25 kW to 2.3 MW. DD PMG’s used [...]

How a Magnetic Drive Pump Works

How a Magnetic Drive Pump Works A magnetic drive pump is a pump that is powered through the use of the science of magnetism rather than electricity from an outside source. Magnetic drive pumps are energy efficient and require no seals or lubricants for operation. Magnetic drive pumps circulate a variety of fluids including acids, [...]

  • Wind Turbine Module Magnetic Assembly

Wind Turbine Module Magnetic Assembly

Wind Turbine Module Magnetic Assembly During the mounting process of MW-grade Motor/Generator’s magnetic rotor, the NdFeB magnets can be easily damaged during assembly. In this circumstance, the magnet fragment and dust are easily stick and attached to the contact surface between magnet and yoke, which would increase the gap distance and even more, lead to [...]
