Magnetization direction and angle of high speed motor magnetic tile
Jan 11, 2019

High-speed motor magnetic tiles have a strong exchange coupling between adjacent electrons in the ferromagnetic material. In the absence of an external magnetic field, their spin magnetic moments can “spontaneously” in a small area. "Linearly arranged to form 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 high-speed motor magnetic tile is in use, when the electric ferromagnetic material is in an external magnetic field, the volume of the magnetic tile whose self-generating 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 the magnetic tile The direction of magnetization is further turned to the direction of the external magnetic field.

High-speed motor magnetic tile is widely used in the manufacture of high-efficiency and lightweight DC motors such as industrial electrical equipment and automotive electrical systems, such as geared motors, servo DC motors, automobile and motorcycle starter motors, automotive door and window lift motors, wiper motors, seat motors, Cold and warm wind motor, oil pump motor, motorcycle magneto, treadmill motor, car ABS system, door lock motor and power tools.
