Abstract

The invention discloses a magnetizing fixture for multi-pole magnetization of the outer circumference surface of an annular magnet. The magnetizing fixture comprises a tubular substrate with an upper open end and a lower open end and 2n magnetizing coils, wherein n is an integer more than or equal to 1; each magnetizing coil includes a spiral magnetizing pole head and a multi-turn lead winding on the spiral magnetizing pole head; the spiral magnetizing pole head takes the shape of a spiral which is formed by stretching along a cylindrical spiral from a horizontal reference plane; the spiral magnetizing pole head is provided with a left curved surface, a right curved surface, an upper end face, a lower end face, an internal cylindrical surface and an external cylindrical surface; one lead is formed into the multi-turn lead by uniformly winding on a closed ring surface formed by the left curved surface, the right curved surface, the upper end face and the lower end face of the spiral magnetizing pole head. The magnetizing fixture adopts the winding manner of winding the single lead, thus being simple in winding mode, uniform in winding displacement, high in magnetizing field energy and magnetizing consistency; and furthermore, due to the single lead, the potential safety hazard of electric leakage caused by damage is inexistent, and thereby the magnetizing fixture is high in safety.

Description

technical field [0001] The invention relates to a magnetizing fixture, in particular to a magnetizing fixture for multi-pole magnetization on the outer surface of a ring magnet. Background technique [0002] The principle of the magnetizing coil is to generate an induced magnetic field by an energized solenoid. The magnetic field strength is related to the energizing current and the number of coil turns. Under the same magnetizing current strength, the more coil turns, the greater the magnetic field strength. The direction of the magnetic field is according to the right-hand rule, the four fingers point to the direction of the current, and the thumb points to the direction of the N pole of the magnetic field. At present, when the magnetic ring is magnetized with multiple poles on the outer circular surface, it is usually necessary to install the magnetic ring in the magnetizing fixture connected to the magnetizing machine, and then turn on the magnetizing machine to magneti...
