Permanent Magnetic Materials Test System
Permanent magnetic materials refer to materials with wide hysteresis loops, high coercive force, high remanence, and can maintain constant magnetic properties once magnetized, also known as hard magnetic materials.
Commonly used important permanent magnet materials mainly include:
1. Rare earth permanent magnet materials, such as NdFeB rare earth alloy permanent magnet materials.
2. Metal permanent magnet materials, such as AlNiCo and FeCrCo.
3. Ferrite permanent magnet materials, such as barium ferrite and strontium ferrite, etc.
4. Other permanent magnet materials, such as micro powder permanent magnet materials, nano permanent magnet materials, plastic permanent magnet materials, machinable permanent magnet materials, etc.
The magnetic performance measurement of permanent magnet materials mainly include:
Saturation magnetization field strength Hmax, remanence Br, coercive force Hcb, intrinsic coercive force Hcj, maximum energy product (BH)max, recovery permeability μrec, hysteresis loop and demagnetization curve.
DX series Permanent Magnetic Materials Test Systems
CE certificate of Permanent Magnet Measuring System
The DX-2012AM permanent magnet magnetic declination measuring instrument is composed of a three-dimensional Helmholtz coil connected to an independent three-component fluxmeter, which constitutes the hardware test part. The three-component test data is converted by a computer to form a complete set of permanent magnets Material quality testing system.
The heating pole head of the electromagnet is used to complete the heating of the magnetic steel (separate closed-circuit electromagnet heating and conduction heating through the fixture) and cooperate with the fluxmeter and the standard one-dimensional Helmholtz coil to measure the magnetic flux at different temperatures (or Magnetic moment) change to obtain the thermal magnetic flux density loss curve.
The DX-2012MQ rare earth permanent magnet material quality test device uses a fluxmeter to configure a one-dimensional Helmholtz coil, which is mainly used to measure the magnetic flux of the permanent magnet device under the condition of the coil, multiplying the coil constantly to obtain the magnetic moment of the device. For the size of the sample, the materials Br, Hcb, and BHmax can be derived.
DX-2012H DC Hysteresis Graph Test System is a BH Loop tracer to measure the remanence Br, coercive force Hcb, internal magnetism of various ferrites, alnico, neodymium iron boron and samarium cobalt and other permanent magnetic materials. Magnetic performance parameters such as coercive force Hcj and maximum magnetic energy product BHmax, and display BH hysteresis loop and demagnetization curve.
