Company profile
The company boasts the first domestically developed servo
fully-automatic wet press oil press machine and the first
dual-track roller kiln in the nation. It also possesses the
capability for independent design, development, and processing of
various types of molds.
The primary business of the company focuses on sintered ferrite
permanent magnet components, encompassing automotive motors,
motorcycle motors, general machinery motors, household appliance
motors, household fan motors, variable frequency motors, water pump
motors, and more. These products are widely used in the automotive,
motorcycle, office equipment, power tools, household appliances,
and fitness equipment industries.
What is universal motor?
General purpose motor is a type of motor widely used in household
appliances, industrial equipment, automobiles and aerospace. It has
the characteristics of simple structure, wide application range and
stable performance, so it has a wide range of applications in
various fields.
The general purpose motor is usually composed of two parts: a
stator and a rotor. The stator is composed of an iron core and a
coil, the coil is energized to produce a magnetic field, and the
rotor is powered by a power supply and subjected to the
electromagnetic force to produce rotation. General motors can be
divided into DC motors and AC motors according to different power
supplies and working principles.
What is permanent magnet ferrite?
Permanent magnet ferrite has a very high magnetic energy product
and coercivity, it can produce a large magnetic field and magnetic
force under a small size and weight, while having a high magnetic
temperature coefficient and thermal stability, can maintain stable
magnetic properties at higher temperatures. This makes the
permanent magnet ferrite still able to work normally in a high
temperature environment and is not easy to lose magnetism. Good
corrosion resistance and wear resistance, so that it is not easily
affected by the external environment and damage.
