<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive canned motor which is efficient as a motor and is little in dispersion of performance. <P>SOLUTION: In this canned motor 50 which has a can 52 for isolating and sealing the stator core 60 of a DC brushless motor from a rotor magnet 68, the can 52 has a core positioning part 62 which positions the stator core 60 in the rotational direction of the rotor magnet 68 and a sensor positioning part 76 which positions the magnetic sensor 74 for detecting the magnetic pole of the rotor magnet 68, in the rotational direction of the rotor magnet 68. It is to be desired that the above core positioning part 62 should be recessed. Moreover, it is to be desired that the above sensor positioning part 76 should be recessed in parallel with the rotating shaft of the rotor magnet 68, or recessed in parallel with a sensor board for mounting a magnetic sensor 74. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
