Hengdian Kim Dae-magnetic plant manufacturers _ ----- magnet magnet manufacturers talk about giant magnetostrictive material applied magnet manufacturers talk about giant magnetostrictive material applied magnet manufacturers tell you, when the external field changes , length and volume of the magnetic material should be small changes quality magnet dealer, this phenomenon is called magnetostriction. Wherein the change in length is called a linear magnetostriction, the volume change in volume is called magnetostriction. Magnetostrictive linear magnetostrictive volume is much weaker than the magnetic quality companies, generally refers to mention magnetostrictive linear magnetostrictive. Since magnetic materials with different magnetic state will produce scalable, so if they are using an alternating magnetic field magnet quality brand, they will produce mechanical vibration. Thus, the electromagnetic energy is converted into mechanical energy. Hengdian Kim factory ----- magnetic NdFeB magnet factory to talk about the role played in the motor NdFeB what quality NdFeB magnet factory tell you, a lot of high-performance NdFeB permanent magnet materials are By using the role in the motor, and the use of permanent magnet materials motor is often called permanent magnet motor. Permanent magnet motors are divided into ferrite and rare earth permanent magnet motor excitation motors. Motor is a magnetic field as a medium for electromagnetic mechanical energy and electrical energy conversion between. Performed to establish the air-gap magnetic field necessary for electromechanical energy conversion in the motor, there are two methods: in the motor windings through the current generator, which requires a dedicated windings and corresponding apparatus, the need to provide energy to maintain constant current flow, usually called electrical excitation motor, such as an ordinary DC motors and synchronous motors; with a permanent magnet to generate a magnetic field, can simplify the structure of the motor, but also save energy, which is a permanent magnet motor.
