The size,shape and grade of magnet can be produced according to your request.
Welcome to contact us for futher informations.
Available dimensions
Radial oriented neodymium ring magnets have advantages on assembly technique,the complete ring have less parts,can simplify and easily realize automatic assembly.
The Out diameter higher precision,better coaxiality and verticality.Have flexible way to choose different ways of magnetizing,include magnetizing poles and angles.Also have highly reliable,no risk of magnet peel off.The most important things is to improve the motor performance,as this ring have very small air gap,motor have smoother operating performance with less noise and vibration.
