Title (EN) MOTOR PUMP WITH IMPELLER ROTOR
(FR) POMPE MOTRICE AVEC ROTOR A IMPULSEUR
Abstract:
(EN) A motor equipment for various pumps, blowers, compressors, dust collectors, cleaners, etc. in which the fluid is sucked and/or discharged through an impeller. Since the conventional motor equipment of this kind consists of a combination of an equipment and a motor for driving the equipment in such a manner that the equipment obtains its power from the motor coupled with the equipment, it has such disadvantages as a large size, and difficulties in its airtight sealing particularly for the equipment necessary for high pressure in sucking or discharging fluid. This invention generally consists of a non-magnetic cylindrical tube (3) which is used as a part of a fluid conduit, a motor stator (4) attached onto the outer periphery of the tube (3), and a motor rotor (2) mounted within the tube (3), said motor rotor being provided with an impeller (1) at the center thereof, and said rotor (2) rotating by means of revolving magnetic field applied from the energized stator (4) within the tube (3) to thereby suck or discharge the fluid by means of the impeller (1) integral with the revolving rotor (2).
(FR) Equipement moteur pour pompes, souffleuses, compresseurs, collecteurs de poussieres, nettoyeuses, etc., dans lequel le fluide est aspire et/ou refoule a travers un impulseur. L"equipement moteur conventionnel de ce genre, consistant en une combinaison d"un equipement et d"un moteur qui entraine i"equipement de telle maniere qu"il obtienne sa puissance du moteur accouple a l"equipement, presente des inconvenients tels que les grandes dimensions, et les difficultes d"etancheite.
