Multipolar ring magnets are a type of magnet that consist of multiple poles arranged around the circumference of a ring-shaped magnet. These magnets are incredibly versatile and are used in a range of industries for a variety of purposes.
One of the key advantages of multipolar ring magnets is their ability to create a strong, uniform magnetic field. This means that they can be used in applications where a consistent magnetic field is required, such as in electric motors, generators, and sensors.
Another advantage of these magnets is their high magnetic strength. They are capable of producing a stronger magnetic field than many other types of magnets, which makes them ideal for use in high-powered applications.
Multipolar ring magnets are also highly customizable. They can be manufactured in a range of sizes, shapes, and magnetic strengths to meet the specific needs of different applications. They can also be coated with various materials to protect them from corrosion and damage, such as epoxy, nickel, or gold plating.
These magnets are commonly used in the automotive industry, where they are used in electric power steering systems, throttle control systems, and brake systems. They are also used in the aerospace industry, where they are used in navigation and control systems, as well as in medical devices, such as MRI machines.
In addition to their industrial applications, multipolar ring magnets have a range of uses in the home and office. They are commonly used to hold notes and pictures on refrigerators or whiteboards, as well as in jewelry and other decorative items.
Overall, multipolar ring magnets are a versatile and powerful magnet that can be used in a range of applications. With their ability to create strong, uniform magnetic fields, their high magnetic strength, and their customizability, they are an ideal choice for many industries and applications.
If you are looking to purchase multipolar ring magnets for your business, be sure to work with a reputable manufacturer that can provide you with high-quality magnets that meet your specific needs. With the right magnets, you can improve the efficiency and effectiveness of your applications, and ultimately, boost your bottom line.
Multi-pole magnetized magnetic rings are more common on bonded NdFeB magnets. This bonded NdFeB magnet is an isotropic permanent magnet material that can be magnetized in any direction. Depending on the design of the motor, the bonded NdFeB magnetic ring may be used as the inner rotor or the outer rotor of the motor.
When bonded NdFeB magnets are used as inner and outer rotors, they are mainly different in the following aspects.
1. The transmission mode is different: In the inner rotor motor, the rotor magnetic ring rotates with the main shaft, the motor frame is fixed, the outer shell is used as the stator, and the magnetic ring and the main shaft are used as the rotor. In the outer rotor motor, the rotor magnetic ring rotates with the motor casing, the motor shaft is fixed, the casing and the magnetic ring are the rotor, and the inner and main shaft are the stator.
2. Difference in number of poles: The magnetic ring of the inner rotor generally has fewer poles, high speed, and small torque; the magnetic ring of the outer rotor generally has more poles, low speed, and large torque.
3. Size and volume difference: The magnetic ring of the outer rotor permanent magnet motor is relatively small, especially the overall length of the motor is small and the center of gravity is low, which ensures the stability of the stirring system. The magnetic ring of the inner rotor motor is larger, especially the length of the motor is longer, the center of gravity is higher, and the running stability is poor. Due to the shorter length of the outer rotor motor, its space applicability is wider, and it is less constrained by the installation longitudinal space.
4. In terms of heat dissipation, the heat dissipation effect of the inner rotor permanent magnet motor is usually better than that of the outer rotor permanent magnet motor. According to design requirements, some motors require the magnetic ring to have a certain magnetization angle to reduce running yaw and high-speed noise.
Multi-pole magnetic rings are mostly used in permanent magnet sensors and driven stepper or brushless motors. If you have strict requirements on the number of magnetized poles, pole width, and pole difference, it is recommended to discuss with our engineers.
