Magnet manufacturer introduce three elements of magnetic materials
Magnet manufacturer introduces general magnetic material performance can be represented by the four parameters, namely the residual magnetic induction intensity,
Unit Gs or fine long hair gauss (mT), 1 mT = 10 Gs)
The coercive force of Hcb (
Unit oster Oe)
The intrinsic coercive force Hcj (
Unit oster Oe)
, the maximum magnetic energy product (
High unit mega Mr MGOe)
, Br, Hcj, (
Max three parameters is the most direct means.
Br, Hcj, (
The mutual relations between Max Br generally think that the size of the magnetic parts after magnetization of the surface of the magnetic field of high and low;
Hcj can show the size of the magnetic resistance to demagnetization after magnetization and heat resistance of high and low ability;
Max is a maximum value of the product of Br and Hcj, it directly shows the size of the magnet performance.
At present we haven't detected bonded NdFeB (
Max can more than 11.
5 the magnets.
In general, (
High Max similar magnet, Br, Hcj is low;
Hcj is high, the Br is low.
We can't just to (
The Max height to determine the quality of the products it remains to be seen whether the Br and Hcj height is suitable for the products we need.
The three size whether to show the stand or fall of material we can't to Br, Hcj,
Max to determine the stand or fall of on any account, magnet manufacturers in product features needed for the purpose, to determine the three high and low;
Even in the same (
Max value under the condition of, also want to see, the magnetization of requirements to determine the purpose of the product using high Br value, low Hcj, or vice versa.
Three size on the effect of magnetization is well known, under the same conditions, which are the same size, the number of the same and the same magnetizing voltage, high magnetic energy product of magnetic table for magnetic is high also, but in the same (
Max value, Br and Hcj of magnetization has the following effects: the Br is high, low Hcj: under the same magnetizing voltage, can get higher magnetic table;
Br is low, high Hcj: to get the same table, the magnetization voltage needed higher;
For a multi-polar magnetization, to adopt high Br Hcj low magnetic powder, and for magnetic tile, magnet manufacturers generally adopt the Hcj high Br low magnetic powder, this is due to the magnetic tile used for motor in use to bear larger demagnetization current and overload.
