Custom Neodymium Arc Magnet

Neodymium arc magnets, or neodymium segment magnets, can be seen as a part of neodymium ring magnets or neodymium disc magnets. They are made of high-quality neodymium magnets containing the elements neodymium, iron, and boron. NdFeB magnets are permanent magnets and the most widely used type of rare earth magnets. Neodymium arc magnets are mostly used in voice coil motor, permanent magnet motors, generators, wind turbines, torque couplings, and other applications.

Neodymium arc magnets are mainly used in permanent magnet DC motors. Unlike electromagnetic motors that generate magnetic potential sources through excitation coils, PM motors use permanent magnet materials to generate constant magnetic potential sources. Instead of electric excitation, permanent arc magnets have many advantages, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, and low in energy consumption.

We are specialized in manufacturing and supplying neodymium arc magnets applied in various industrial applications. We have advanced technology, rich experience, and professional engineering technicians in this field. If you require a specific size, please contact us for a custom magnet quote.
