  1. Coreless Motor Ring Magnet Superiority: Sintered NdFeB permanent magnets, known for their high remanence, high coercivity, and high energy products, are the optimal choice for coreless motors. Their properties align perfectly with the demands of coreless motor applications.
  2. Market-Leading Magnet Material: As the most suitable permanent magnet material available, sintered NdFeB magnets are the gold standard for coreless motors. They outperform other materials in meeting the specific needs of these motors.
  3. Magnet Strength and Motor Speed: The strength of the magnets used in coreless motors directly impacts the motor’s speed. Therefore, selecting the right magnet is crucial for achieving the desired motor performance.
  4. Common Neodymium Magnet Profiles: Ring-shaped neodymium magnets, such as N45SH and N48SH grades, are commonly used in coreless motors due to their excellent performance characteristics and temperature resistance of approximately 150°C.
  5. Micro ring magnets: the minimum diameter of the coreless motor magnetic ring is 2.5mm and the maximum is 50mm, the minimum height is 1.5mm, and the maximum height is 50mm.

Coreless motors are categorized into two variants: brushed and brushless. Brushless coreless motors lack an iron core in the rotor, while brushless coreless motors do not have an iron core in the stator. Commonly available coreless motors in the market come in various diameters, such as Φ4, Φ6, Φ7, Φ8, Φ10, Φ12, Φ15, Φ16, Φ17, Φ18, Φ19, Φ20, etc.

The Applications of Coreless Motors

Following their entry into the industrial and civilian sectors from military and high-tech domains over a decade ago, coreless motors have seen rapid application growth. This is especially prevalent in industrially developed nations, where they have become integral to most industries and a multitude of products.
1. Coreless motors are adept at fulfilling the technical demands of rapid-response systems, such as the prompt adjustment of missile flight paths, the precise follow-up control in high-magnification optical drives, swift automatic focusing, highly sensitive recording and detection devices, industrial robotics, bionic prosthetics, and more.
2. They are ideal for applications requiring stable and enduring drive components, such as various portable instruments, personal devices, and field operation equipment, as well as electric vehicles. Using coreless motors can extend battery life by over twice as much with the same power supply.
3. Coreless motors are used in a variety of aircraft, including those for aviation, aerospace, and modeling. Due to their lightweight, compact size, and low energy consumption, they maximize weight reduction. Moreover, they are utilized in a spectrum of civil electrical appliances and industrial products, enhancing product quality and performance when used as actuators.
4. Due to their compact size, coreless motors are the power component of choice for many products with size constraints, such as toys (e.g., toy cars, model airplanes), massage products (e.g., washing brushes, induction instruments, facial massagers), and daily necessities (e.g., electric toothbrushes, shampoo brushes, hair straighteners).
