Permanent bonded neodymium ring magnets

We now offers high efficiency Permanent bonded neodymium ring magnets.

Isotropic bonded NdFeB materials can be magnetized in any direction, or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple pole magnetization. isotropic resin bonded Neodymium-Iron-Boron material offers a high energy product with an exceptional resistance to demagnetisation. Capable of operating up to 120ºC. Ring magnets may be machined from discs.

Being isotropic, most shapes can be magnetised in any direction. bonded neodymium ring magnets may have either axial or diametric poles. Minimum field strength to magnetise to saturation is 3000kA/m (37500 0e). Such multipole fixtures may cost several thousands of dollars depending on design complexity and production rate requirements.

Brushless dc motors and encoders are highly suited applications for bonded neodymium ring magnets, thanks largely to their ability to press and multi-pole magnetise single component magnet rings. These are not the only applications they can be used for though, with latching solenoids (used in position sensors) and actuators (used in door and window locking and lift motors) also finding a use for these magnets. Electrical powered assisted steering systems also make good use of the multi-pole, skewered magnetisation bonded neodymium ring magnets, offering excellent control feedback. In fact, a good range of industries benefit from this particular magnet type, including the manufacture of domestic appliances, aerospace and the automotive industry.
