8 Pole Neodymium Magnet Ring For Spinder Motor +/-0.05mm Tolerance
Product Description:
Bonded neodymium magnet is a kind of permanent magnetic material
which is made from neodymium iron boron alloy powder and adhesive.
It has excellent magnetic properties and is widely used in spinder
motor, stepping motor, synchronous motor, DC motor, brushless
motor, etc. It can be magnetized in axial, radial, multi-poles
direction and is available in various shapes like disc, block,
cylinder, ring, etc. It can withstand the maximum operating
temperature up to 120°C without losing its magnetic properties.
Bonded neodymium magnet offers many advantages such as high
coercivity, low cost, and wide working temperature range. It is
widely used in various applications such as electric motors,
loudspeakers, magnetic separators, sensors, pumps, and medical
equipment.
Our bonded neodymium magnet has excellent magnetic properties and
is highly resistant to demagnetization. It has strong adhesive
force and can be easily bonded to other materials. Our bonded
neodymium magnet is available in various sizes, shapes, and
thickness. It is also available in a wide range of colors,
finishes, and coatings. Whether you need a bonded neodymium magnet
ring 8 pole or other special shape, we can meet your requirements.
