High Performance Permanent Magnet Ferrite In Convenient Living
Assistant Microwave Ovens
The role of permanent magnet ferrite in microwave oven:
Shielding and interference suppression: Inside the microwave oven,
it is very important for the management of electromagnetic waves.
Permanent magnet ferrite can be used as a shielding material to
reduce electromagnetic interference, thereby improving the
efficiency and safety of microwave ovens.
Energy conversion and regulation: In some high-end microwave ovens,
permanent magnet ferrite may be used to regulate the distribution
of energy to help achieve more precise heating effects.
Cost and performance: Compared with other materials, permanent
magnet ferrite is usually cheaper and stable, so it has a certain
application value in consumer electronics such as microwave ovens.
The role of permanent magnet ferrite in Household Appliances motor:
Permanent magnet ferrite plays an important role in household
appliances. It is commonly used as a magnet for motors and
generators, for example in vacuum cleaners, refrigerators, fans,
air conditioners and washing machines. These permanent magnet
ferrite magnets can produce a constant and stable magnetic field,
so that the motor can effectively rotate, so as to achieve the work
of household appliances. Compared with other magnets, permanent
magnet ferrite has higher magnetic energy products and stable
magnetic properties, so it has been widely used in household
appliances.
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.
