The use of high speed motor magnetic tile
May 04, 2018

High speed motor magnetic tiles are one kind of magnets that are mainly used in high-speed permanent magnet motors. At the Curie temperature, there are many small regions within the ferromagnetic or ferrimagnetic material that each have their own spontaneous magnetic moments and whose magnetic moments are paired. The direction in which they are arranged is very turbulent. If no magnetic field is used for magnetization, the magnetic moment is zero as a whole. These small areas will also be called high-speed motor tiles.

 

Below the Curie temperature, there are many small regions within the ferromagnetic or ferrimagnetic material that each have a spontaneous magnetic moment and a pair of magnetic moments. The direction in which they are arranged is very turbulent. If no magnetic field is used for magnetization, the magnetic moment is zero as a whole. In ferromagnetic materials that have not been magnetized, although each magnetic tile has a definite spontaneous magnetization direction and a large amount of magnetism inside, a large number of magnetization magnets have different magnetization directions and the entire ferromagnetic material is not magnetic.

 

When the high speed motor magnetic tile is used, it should be noted that when the magnetic field of the ferrite is in the external magnetic field, the volume of the magnetic tile whose self-magnetization direction and the direction of the external magnetic field is at a small angle increases with the applied magnetic field. Expand and turn the magnetization direction of the tile further toward the direction of the external magnetic field.

 

High-speed motor magnetic tiles are mainly used in permanent magnet DC motors, and electromagnetic motors generate magnetic potential sources different from the excitation coils. Permanent magnet motors use permanent magnetic materials to generate a constant magnetic potential source. This high-speed motor magnetic shoe 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, less in copper, low in copper consumption, and low in energy consumption.

 

High-speed motor magnetic tile in the installation will generally be divided into two kinds, one is a low speed, with AB glue for bonding; one is a high speed adhesive with AB glue and then fixed with a stainless steel sleeve; will only use AB A lot of adhesive bonding adds a layer of silicone rubber on the outside, so that it can not be used for fixing, it can also prevent the iron material from adsorbing to the surface of the magnetic steel, or removing the electrophoretic layer of the magnetic steel when it is removed! With regard to the use of high-speed motor magnetic tiles, bonding with AB glue with diameters of up to 3000 RPM and less than 55 is not a big problem!
