PURPOSE:To simplify the mounting of a magnet holder in a pump, by integrally forming the magnet holder with a rotor secondary conductor through die casting. CONSTITUTION:A driving magnet 8 is supported by a magnet holde 28. The magnet holder 28 is arranged so as to be integrally rotated with a rotor 4 at a load side of the rotor 4. The magnet holder 28, being integrally formed with a secondary conductor 12 by aluminum die casting, eliminates the necessity for a washer, nut, etc. required for fixing a conventional magnet holder. Further a rotor shaft 27, if supported by bearings 5, 6 in a cantilever state, is not protruded to the load side from the rotor 4, then its length can be reduced. |
