1. A laminated busbar assembly of a motor controller, comprising:
a circular main circuit board;
a circular positive electrode connection plate, an outer edge thereof being circumferentially provided with multiple positive electrode pins;
a circular negative electrode connection plate, an outer edge thereof being circumferentially provided with multiple negative electrode pins; and
a three-phase connection plate assembly, comprising three single-phase connection plates, which are fan-shaped or arcuate, and an outer edge of each of the three single-phase connection plates is provided with multiple single-phase pins in a circumferential direction of the each of the three single-phase connection plates; and
wherein, the main circuit board, the three-phase connection plate assembly, the negative electrode connection plate, and the positive electrode connection plate are laminated along a direction perpendicular to a plane of the positive electrode connection plate; the three single-phase connection plates are coplanar; and the multiple positive electrode pins, the multiple negative electrode pins, and the multiple single-phase pins pass through the main circuit board and are electrically connected with the main circuit board.
