Abstract
A rotor structure, a permanent magnet auxiliary synchronous reluctance motor and an electric vehicle are provided. The rotor structure includes a rotor body. A permanent magnet groove group is provided on the rotor body, the permanent magnet groove group includes an outer layer permanent magnet groove and an inner layer permanent magnet groove, and a magnetic conduction channel is formed between the outer permanent magnet groove and the inner layer permanent magnet groove which are adjacent. A deflection segment is formed on at least one end of the magnetic conduction channel, and a distance from the deflection segment to a quadrature-axis of the rotor body is decreased gradually outward in a radial direction, so that an end of the magnetic conduction channel is disposed near the quadrature-axis.
