Ferrite magnetBig Secret manufacturers it! For the uninitiated, the ferrite tile is in the minds of consumers has been wrapped in a layer of mystery, people can not figure it? Do not worry, today small will take you into the world of ferrite tile!
Magnetic ferrite magnetic tile can have a high performance magnetic permeability at high frequencies. Thus, a wide range of high-frequency ferrite has become weak areas of use of non-metallic material. Since the ferrite magnetic energy accumulated per unit volume low saturation magnetization lower (usually only iron 1 / 3-1 / 5), which limits its application in demanding low frequency magnetic energy density and high power electric field strength.
Ferrite magnetic tile mainly used in permanent magnet DC motor with electromagnetic motors have different magnetic potential source through the excitation coil, permanent magnet motor is a permanent magnet material to produce a constant magnetic potential sources. Tile instead of permanent magnet excitation power has many advantages, make simple motor structure, easy maintenance, light weight, small size, reliable, use less copper, low copper consumption, energy consumption and small.
Influence of magnetic-watt motor performance
(1) a high residual magnetic flux density Br. Br high to ensure that the motor because there is a high speed, high torque and high output power. The motor will have high efficiency.
(2) high Hcb. Because Hcb high, in order to ensure the required motor output electromotive force, the motor operating point close to the maximum energy product, the ability to take full advantage of the magnet.
(3) high Hcj. Hcj high can ensure that the motor has a strong resistance to demagnetization overload and anti-aging, anti-low temperature.
(4) a high (BH) max. (BH) max higher scores indicating better permanent ferrite in the motor duty factor actually running.
(5) magnetic energy Φ better, which will greatly improve the efficiency of the motor.
Squareness (6) of the demagnetization curve, the better, the smaller the dynamic losses of the motor.
(7) Ferrite higher resistivity, the smaller the eddy current losses.
(8) permanent ferrite temperature coefficient is small, at high temperatures it has a good temperature stability
