Abstract:
A method for assembling an electric motor of the type comprising a stator unit (5) and a rotary unit (6) housed in a containment compartment (2a) delimited by a casing (2), comprises the step of exposing the compartment (2a) to a different pressure relative to the outside environment and the step of checking for the passage of fluid between the outside environment and the compartment (2a) in order to test the motor (1) hermetic seal.
