Document Type and Number:
WIPO Patent Application WO/2019/105633
Kind Code:
A1
Abstract:
The present invention relates to a rotor (1) suitable for use in a permanent magnet synchronous electric motor (19) of a hermetic compressor (20), rotating in a stator (15) about a rotary axis (E) formed by a shaft (17) mounted in a shaft hole (16) in its center, having an air gap (18) in between itself and the inner surface of the stator (15), comprising a core (2) made of ferromagnetic laminations or ferromagnetic metal powders, a plurality of magnets (3) placed circumferentially adjacent with equal space in between on the core (2), whose transversal section vertical to the rotary axis (E) is shaped as an arc segment curved in radial direction from the circumference of the core (2) towards its center, having a convex lower surface (4) contacting the core (2) and a concave upper surface (5) not contacting the core (2).
