Abstract
A rotor, including: a rotor core and a plurality of permanent magnets. The rotor core includes an axle hole, four slots equally distributed at the outer side of the axle hole, first magnetic isolating slots, and second magnetic isolating slots. The first magnetic isolating slots are disposed at each side of each of two adjacent slots, and the second magnetic isolating slots are disposed at each side of each of the other two adjacent slots. Both the first magnetic isolating slots and the second magnetic isolating slots communicate with corresponding slots. Two lines connecting a center of the axle hole and two first magnetic isolating slots respectively at both sides of one slot form a first angle at the center, and two lines connecting the center of the axle hole and two second magnetic isolating slots respectively at both sides of one slot form a second angle at the center.
