Abstract
A process for magnetizing the permanent magnets of an electric motor rotor and a process for assembling a hermetic compressor motor, whose stator ( ) carries a plurality of coils ( ), said rotor being operationally positioned with a determined relative angular position in relation to the stator ( ) prior to the energization, from an external current source, of a determined number of coils ( ) of said stator ( ) with a current pulse having a required intensity to generate a magnetic field which produces a homogeneous magnetization transversely oriented in at least one magnetic sector, said current pulse being maintained during a shorter time than that which impairs the coils of said stator ( ).
