Permanent Magnet Ferrite For Continuous Stability In Variable
Frequency Motors For Air Conditioning
Our company manufactures an-isotropic ceramic strontium ferrite
magnet made by means of wet compression molding.
What is permanent magnet ferrite?
Permanent magnet ferrite is a hexagon structure compound with
uniaxial anisotropy, mainly barium, strontium, lead three kinds of
ferrite and their composite solid solution, there are the same
magnetic and opposite magnetic points, because this kind of ferrite
material in the external magnetization field disappeared, still can
retain a strong constant remanent magnetic property for a long
time, can be used to generate a stable magnetic field on the
external space.
What are the advantages of the permanent magnet ferrite we produce?
1,Stable magnetic properties: permanent magnet ferrite has high
coercivity and remanence, stable magnetic properties, and is not
easily affected by external influences.
2,High temperature resistance: permanent magnet ferrite has good
high temperature resistance and is suitable for use in high
temperature environment.
3,High temperature coefficient of resistance to saturated magnetic
field: The magnetic properties of permanent magnet ferrite decay
slowly at high temperatures, with a high temperature coefficient of
resistance to saturated magnetic field.
4,Low cost: The raw material price of permanent magnet ferrite is
low, the production process is simple, and the cost is relatively
low.
5,Long service life: permanent magnet ferrite has a long service
life, is not easy to demagnetize, low maintenance costs.
6,Good rare earth substitution: permanent magnet ferrite can
replace some rare earth magnets, reduce the dependence on rare
earth and reduce the consumption of rare earth resources.

what is the Variable frequency motor?
Variable frequency motor is a kind of motor that can adjust the speed and output power according to the need. It controls the frequency and voltage of the power supply through the frequency converter, so as to achieve variable speed operation. Such motors are commonly used in applications where speed needs to be adjusted according to load changes, such as fans, pumps, compressors, and conveyor equipment.
The advantages of variable frequency motor include high efficiency and energy saving, accurate speed regulation, smooth start and stop, and reduce mechanical wear. Because the speed can be adjusted according to the actual demand, it can effectively save energy and extend the life of the equipment.
In the industrial and commercial fields, variable frequency motors are widely used in various industries, such as manufacturing, petrochemical, water treatment, construction and transportation. With the improvement of energy conservation and environmental protection awareness, the application range of variable frequency motors will be further expanded.
