Described fish line conductor hole be shaped as circular, square, trapezoidal or other geometry.
The processing method of slant multiple magnetic pole radial magnetizing clamp may further comprise the steps:
(1) selected shape, size is identical, thickness is 0.1mm ~ 1mm 10-500 sheet cylindrical shape or columniform solid thin-sheet material;
(2) on the same position of the excircle of above-mentioned each sheet solid thin-sheet material or internal and external circumference, process and face cylindrical permanent-magnet body direction opening and quantity, the on all four hole of size are arranged;
(3) obtain every layer of angle value that should rotate according to the final oblique angle that requires divided by total number of plies;
(4) solid thin-sheet is stacked up from top to down, with the solid thin-sheet of a slice below every with respect to a slice solid thin-sheet of next-door neighbour on it, center with solid thin-sheet is a benchmark, rotation angle value according to aforementioned calculation, clockwise direction or counter clockwise direction are rotated vertically, are formed with the fish line conductor hole of opening after the stack;
(5) in the fish line conductor hole around on the lead that magnetizes.
The present invention has realized external circumference of cylindrical permanent-magnet or inner periphery are carried out slant multiple magnetic pole radial magnetizing; And process simple, easy to manufacture, with low cost, wire guide precision height.
