1. A magnetic pole module, installed on a rotor support of a permanent magnetic generator, wherein, the magnetic pole module comprises:
a base plate, having a first surface and a second surface arranged opposite to each other along a thickness direction of the base plate, wherein, the base plate has a first center line extending in a first direction and a second center line extending in a second direction, and the first direction is intersected with the second direction, the first center line is parallel to a central axis of the permanent magnet generator;
at least one pair of magnetic steel components, fixed on the base plate, wherein, each pair of magnetic steel components is symmetrically arranged on the first surface relative to the second center line, each magnetic steel component comprises a plurality of magnetic steels arranged side by side in a side of the first direction from the second center line and at a predetermined angle in the second direction,
wherein, a plurality of magnetic steels of each magnetic steel component is successively staggered in a same direction in the second direction, and a connecting line between a midpoint of a cross section of each magnetic steel includes a first line segment, a second line segment and a third line segment successively connected in a side of the first direction from the second central line,
a first included angle between the first line segment and the first center line is θ1, a second included angle between the second line segment and the first center line is θ2, and a third included angle between the third line segment and the first center line is θ3,
wherein, a cross section of the magnetic steel is of a rectangular shape, which comprises a pair of first sides arranged oppositely and a pair of second sides arranged oppositely, the pair of first sides is parallel to the first direction, the pair of second sides is parallel to the second direction or is arranged at the predetermined angle with the second direction,
wherein, the base plate further comprises a first side wall and a second side wall which are arranged opposite to each other in the second direction, the first side wall and the second side wall are connected with the first surface and the second surface and extend in the first direction, and the first side wall recesses inwards in the second direction to form a first tangent plane and a first bottom wall which are intersected with each other, the second side wall recesses inwards in the second direction to form a second tangent plane and a second bottom wall which are intersected with each other, the first surface is connected with the first bottom wall and the second bottom wall, and the first tangent plane and the second tangent plane are lower than the first surface.
