Rare earth neodymium arc magnets
Arc Magnets are primary used as motor magnets and generator magnets; however, their uses are also as pump magnets, sensor magnets, and automotive magnets. When used as a motor magnet, arc magnets can be arranged is a circular pattern with alternating north and south poles.
What's arc motor magnets？
Below the Curie temperature, there are many small areas within the ferromagnetic or ferrimagnetic material that each have a spontaneous magnetic moment and the magnetic moments are paired. They are arranged in a disordered direction, such as magnetization without a magnetic field, and the magnetic moment is zero as a whole. Magnetic tile
There is a strong "exchange coupling" between adjacent electrons in the ferromagnetic material. In the absence of an external magnetic field, their spin magnetic moments can be "spontaneously" aligned in a small area. It forms a small area of spontaneous magnetization called a magnetic tile. In the unmagnetized ferromagnetic material, although each magnetic tile has a certain spontaneous magnetization direction inside, and has a large magnetic property, the magnetization directions of a large number of magnetic tiles are different, and the entire ferromagnetic material is not magnetic.
When the ferromagnetic material is in an external magnetic field, the volume of the magnetic tile whose spontaneous magnetization direction and the direction of the external magnetic field are at a small angle expands with the increase of the applied magnetic field and further turns the magnetization direction of the magnetic tile to the direction of the external magnetic field.
Features of arc motor magnets
It is mainly used in permanent magnet DC motors. Unlike electromagnetic motors, which generate magnetic potential sources through excitation coils, permanent magnet motors use permanent magnet materials to generate a constant magnetic potential source. The permanent magnet magnetic tile has many advantages instead of electric excitation, which can make the motor simple in structure, convenient in maintenance, light in weight, small in size, reliable in use, low in copper consumption, low in copper consumption, and low in energy consumption.
