Document Type and Number:
WIPO Patent Application WO/2022/160781
Kind Code:
A1
Abstract:
The present application provides a rotor assembly and a self-starting permanent magnet synchronous reluctance motor. The rotor assembly comprises a rotor core (1); in a transverse cross section perpendicular to a central axis of the rotor core (1), each pole of the rotor core (1) comprises at least two layers of mounting grooves (2) which are arranged at intervals along the radial direction; and permanent magnets (3) are mounted within the mounting grooves (2), and q-axis squirrel cage grooves (4) are respectively provided at two ends of the mounting grooves (2). The width of the q-axis squirrel cage grooves (4) along a direction close to the q axis gradually reduces, and the length of the q-axis squirrel cage grooves (4) in the direction close to the q axis gradually increases.
