NdFeB arc shape magnets are widely used in applications that require a strong magnetic field along a curved or circular surface. Their shape allows them to fit precisely into round assemblies, making them essential components in various mechanical and electronic systems.
Motors and Generators
One of the primary applications of NdFeB arc shape magnets is in motors and generators. They are commonly arranged in a circular pattern within rotors or stators to generate a uniform magnetic field. This configuration improves efficiency and performance in devices such as brushless DC motors, wind turbines, and electric vehicle motors. The arc shape allows the magnet to follow the curvature of the rotor, optimizing magnetic flux distribution.
Magnetic Couplings and Bearings
Arc magnets are also used in magnetic couplings and bearings. In these applications, they transmit torque or support rotational motion without direct mechanical contact. The curved design ensures consistent magnetic interaction around the circumference, reducing wear and allowing smooth operation in pumps, mixers, and other rotating machinery.
Sensors and Actuators
NdFeB arc shape magnets are applied in sensors and actuators where precise magnetic positioning is required. Their shape helps create a strong and stable magnetic field over a defined angular segment, enabling accurate measurement of rotational movement. These magnets are used in robotics, industrial automation, and precision instrumentation.
Other Industrial Applications
Additional uses include magnetic separators, loudspeakers, and magnetic clutches. Their high strength and curved design allow efficient magnetic performance in systems where a circular magnetic arrangement is needed.
