Abstract
A rotor sheet includes a sheet body. The sheet body includes a plurality of magnetic poles symmetrically distributed in a circumferential direction of the sheet body. Each magnetic pole includes one first magnet groove symmetrical about a D-axis center line, two second magnet grooves symmetrically distributed in an approximate V shape about the D-axis center line, two first air grooves symmetrically distributed on the outer sides of two ends of the first magnet groove, and one second air groove positioned between the ends of the two second magnet grooves near the side of the center of the sheet body. First magnetic bridges are formed between the first air grooves and an excircle of the sheet body, and second magnetic bridges are formed between the first magnet groove and the first air grooves; and third magnetic bridges are formed between the excircle of the sheet body.
