The electric pump comprises a stationary body (11) which defines a chamber (12) for the liquid and in which is mounted to rotate an impeller body (16) provided with a series of blades (17). The inductor (23) and the armature (24) of a brushless electric motor are formed by two inserts which are embedded in the material of the two bodies (11, 16) during the corresponding moulding thereof. The armature (24) is formed by a series of permanent magnets (31) joined by a ring (32) of ferromagnetic material and it can be disposed in alignment with the blades (17) of the impeller body (16). In this case the ring (32) is provided with a series of projections (33), each of which carries one of said magnets (31) and is adapted to form a core for the corresponding blade (17). <IMAGE> |
