Preparation method for sintering permanent magnetic ferrite ring of brushless motor
The invention discloses a preparation method for a sintering permanent magnetic ferrite ring of a brushless motor, and an objective is to provide a preparation method for a sintering permanent magnetic ferrite bead of a brushless motor, and the method improves magnetic flux density and solves a problem that cracking is easy to occur in a sintering process. The main technology comprises pre-magnetizing blank, breaking and preparing materials, drying and sintering, grinding, and magnetizing, so as to prepare and produce a multipolar magnetic ring whose peak value is 2000 Gs after magnetizing, and solve problems that the inner and outer circles of the magnetic crack caused by the difference value of shrinking percentages in a sintering process of a multipolar molded workblank body. Beneficial effects of the method are that the problems that the inner and outer circles of the magnetic crack caused by the difference value of shrinking percentages in a sintering process of the multipolar molded workblank body is solved, the method ensures the hardness of a mold cavity and service life of moulds, greatly restrains magnetic ring products from cracking in sintering, and improves magnetic flux density of a multipolar radiation magnetic ring.
