Detailed Multipolar Ring Magnet Description
Patent NO.: 90 2 23958.9
This sintered NdFeB multipolar ring magnet parts are the high - tech excellent products,
they are commonly used with Permanent Magnet DC Motor, Permanent Magnet
3 Phase AC Synchronous Servo Motors etc..
The advantages of our newly - developed sintered NdFeB multipolar ring magnet parts
are as follow:
a) The cubage is much smaller than that of tile magnet parts. The Motor has to use the tile
magnet parts before invention of our product.
b) The Max Working Temperature can be enhanceded up to 250 degree.
c) They can be a right substitute for bonded ring magnet parts with much
higher BH () and lower cost.
d) They are, therefore, bound to help greatly enhance the power of
Permanent Magnet 3 Phase AC Synchronous Servo Motors /DC Motors. As you see, we have got the Patent for them, so far we are the
only manufacturer in China.
We are sure the parts will be a revolution of Permanent Magnet DC / AC
Motors. Although the similar magnet parts are available
in Japan, the price is extremely high. The quality of our sintered NdFeB
multipolar ring magnet parts is as good as those of Japan, and the cost
is only one third of Japanese ones because of our unique processing.
