The main purpose of Motor magnet tile and the direction of magnetic field
Oct 09, 2017

Motor magnet tile is a kind of magnet used in the permanent magnet motor on the tile-like magnet, in the Curie temperature below the ferromagnetic or ferromagnetic material there are many spontaneous magnetic moments, and magnetic The small area of the pair. They arranged in the direction of disorder, such as magnetic field without magnetization, from the whole point of view, the magnetic moment is zero. These small areas are called magnetic tiles.

The Motor magnet tiles are below the Curie temperature, and there are many small areas in the ferromagnetic or ferrimagnetic material with spontaneous magnetic moments and magnetic moments. They arranged in the direction of disorder, such as magnetic field without magnetization, from the whole point of view, the magnetic moment is zero.

There is a strong exchange coupling between the adjacent electrons in the ferromagnetic magnet of the Motor magnet tile. In the absence of an external magnetic field, their spin magnetic moments can be "spontaneously" in a tiny area "Neatly arranged to form a spontaneous magnetization of small areas, known as magnetic tile. In the unmagnetized ferromagnetic material, although each magnetic tile internal have a certain direction of spontaneous magnetization, there is a large magnetic, but a large number of magnetic tile magnetization direction is different and thus the entire ferromagnetic is not significant magnetic.

When the ferroelectric magnet is in the external magnetic field, the volume of the Motor magnet tile whose spontaneous magnetization direction and the external magnetic field direction are small angle increases with the increase of the external magnetic field and the direction of magnetization of the magnetic tile is further turned to the direction of the external magnetic field.

The Motor magnet tile is mainly used in the permanent magnet DC motor, and the electromagnetic motor through the excitation coil to produce different magnetic potential, permanent magnet motor is a permanent magnetic material to produce a constant magnetic potential. Permanent magnetic magnetic tile instead of electric excitation has many advantages, can make the motor structure is simple, easy maintenance, light weight, small size, the use of reliable, with less copper, low copper consumption, low energy consumption.
