SYNCHRONOUS ELECTRIC MOTOR WITH PERMANENT MAGNETS AND ELECTRIC COMPRESSOR COMPRISING SUCH AN ELECTRIC MOTOR

摘要

Synchronous electric motor with permanent magnets comprising a wound stator (1) comprising stator teeth extending axially formed in a frame and a rotor (5) comprising a plurality of the magnets extending axially into a cylinder head (6), being embedded according to a flux concentration construction of the rotor (5) in which a first length (Ls1) of the rotor (5) is greater than a second length (Ls1) of the stator teeth and in which a ratio of the first length (Ls1) to the second length (Ls2) is lower than 1.3. The compressor comprises such an electric motor.
