ABSTRACT:
A method for obtaining, in a quick way, a strong, compact and waterproof permanent-magnet rotor (3), intended for a synchronous motor (1), particularly for pumps of washing machines for industrial and domestic use and the like, of the external stator (2) type, comprising a cylindrical hollow core (6) surrounded by a plurality of permanent magnets (10) comprising the steps of arranging a cup-like body (7) with a base end (8a), a free end (8b) and a side wall (9) exhibiting a plurality of passing longitudinal recesses (12) which define, between the same, a plurality of positioning seats (13) for the magnets (10), providing to insert the core (6) into the cup-like body (7) and arrange the magnets (10) in said seats (13) and injecting a plastic material with obtainment of a cage-like structure (50) having opposite bottoms (27, 28) abutting at the ends (8a,8b) of the cup-like body (7) as well as columns (29) extended between the opposite bottoms (27, 28) housed in the recesses (12).The invention also relates to a rotor (3) obtained by means of the present method.
