Benefits of Segment Neodymium Iron Boron Magnets in Motor Applications
At present, most motor manufacturers apply “Magnetic King” NdFeB magnets to motors. Permanent magnet of motor magnetic steel produced by neodymium iron boron magnet: small size, light weight, high torque-inertia ratio, high response of servo system, high power and speed/weight ratio, high starting torque and energy saving.
A few motor manufacturers also use samarium-cobalt magnets and permanent magnets as motor magnets. The shapes of motor magnet are mostly tile-shaped, ring or trapezoidal, and can be used in different motors, such as permanent magnet motors, AC motors, DC motors, linear motors, brushless motors, and the like.
People usually use the attractive force and repulsive force of the magnet to drive. Generally, a radial symmetrically magnetized tile-shaped magnet is selected to form a ring. The sintered NdFeB magnet is an anisotropic material and cannot be molded at one time to make the customer think. A slightly more complicated magnetization direction. At present, magnet manufacturers can also do radial magnetization of sintered NdFeB magnets, but there are many restrictions on the size of the grades, and the magnetic properties are extremely unstable, the consistency is not good, and there are both mold coils and magnetizing fixtures. Expensive, so very few manufacturers will choose it.
Whether domestic or foreign, the demand for motor magnets is very large, and magnets are the core components. Many of the micro-motors, small and medium-sized motors and large generators use NdFeB permanent magnet materials. The NdFeB permanent magnet motor has no excitation coil and iron core. In order to achieve the same air gap magnetic field, the NdFeB magnet has a smaller volume than the original magnetic pole, and there is no loss and no heat. Therefore, in order to obtain the same output characteristics, the volume and weight of the whole machine can be reduced a lot; or the same volume, weight, and output power can be increased a lot.
