POSITIONING STRUCTURE OF ROTOR IN CANNED PUMP AND MAGNETIZING METHOD FOR PERMANENT MAGNET

摘要

PROBLEM TO BE SOLVED: To enable to magnetize a permanent magnet 5 of a canned pump after mounting a rotor 4 in a can 2. SOLUTION: A positioning groove 4b is so formed at the rotor 4 as to be observed through a suction inlet 14a arranged on a bracket 14 that shuts a can opening. A positioning jig 15 inserted through the suction inlet 14a is connected to the positioning groove 4b and formed in one piece, and the positioning of the rotor 4 is conducted by rotating the positioning jig 15.
