Method for assembling electric power supply cables on a stator

Method for assembling electric power supply cables (10) on a stator (12) of an electric motor, in particular a rotary electric motor for hermetic compressors of refrigerators, which stator (12) is formed by a pack (14) of magnetic laminations and at least one winding of bundles of electrically conductive wires (16), which is housed inside cavities (18) formed in the pack (14) and has at least one head (20) projecting from the pack (14), said method comprising the steps of:

• electrically connecting an end (22) of each cable (10) to an end (23) of at least one respective wire (16) of the winding,
• inserting each pair of connected ends (22, 23) into a respective small tube (28) of a protection and positioning element (24) made of insulating plastic and having a strip (26) from which a number of small tubes (28) at least corresponding to the number of electric power supply cables (10) transversally protrudes,
• clamping each of the small tubes (28) so as to fix it-each of the small tubes to the pair of ends (22, 23) inserted inside each of the small tubes,
• inserting an end of said strip (26) inside a cavity (18) of the pack (14), so that said small tubes (28) are located within said head (20) of the winding, and
• tying said winding in the region of the head (20) so as to enclose said small tubes (28), three parallel and superimposed small tubes (28), which have an end closed along the strip (26) and the opposite end open, transversally protruding from the end of the strip (26) opposite to the end inserted into the cavity (18).
