Segment magnets are available in different shapes, such as curved and fan-shaped neodymium magnets, and are commonly used in magnetic rotor systems for advanced motors or generators. Arc magnets, also known as segment magnets or curved magnets, are a specialized form of neodymium or ferrite magnet that possesses a curved or arc-shaped profile. These magnets are commonly used in applications where a specific magnetic field shape or configuration is required, such as in electric motors, generators, sensors, and magnetic assemblies. The arc shape allows for the creation of a radial magnetic field, which is essential for many rotary applications like motors and generators. Neodymium Arc Magnets are typically produced by cutting a larger cylindrical magnet into smaller segments, resulting in curved pieces that can be arranged to form complete circles or arcs. These magnets come in various sizes, strengths, and configurations to suit the specific needs of different applications, offering excellent performance and efficiency in delivering precise magnetic forces in a compact and tailored manner.

Improved corrosion resistance – The HAST protocol used on uncoated Neodymium magnets can qualitatively reflect the service life of the magnet. This test exposes the magnet to 130°C, 95% RH, at 2 ATM for 20 days. The magnet weight is measured before and after the test. Our magnets measure a weight loss of less than 3 mg/cm2. Competitors’ magnets can lose over 10 times more.
Batch-to-batch uniformity – The BHmax of our magnets has a Cpk value greater than 1.6.
High Maximum Working Temperature – Our AH series of NdFeB magnets have working temperatures up to 230°C.
Excellent adhesion of plating to the magnet – Our Rare Earth Neodymium Arc & Wedge Magnets develop up to 2,175 psi attractive force between the plating and the magnet.

Generally, the segment requires grinding and EDM cutting from the big block. Sometimes, the approximate final shape achieved after the EDM cutting needs processing with a shaped diamond grinding wheel which provides the precise dimensions and speeds up the machining process. Prior to coating, the small segment needs vibration tumbling and the big segment needs manual chamfering.
