<P>PROBLEM TO BE SOLVED: To provide a reliable brushless motor capable of precisely detecting magnetic pole of a hall element, along with a pump mounted with it, and manufacturing method thereof. <P>SOLUTION: A hall element holder 62a3 is integrally molded with an annular ring 62a2 of an insulator 62 of a stator 60. After a hall element 71 is stored in the hall element holder 62a3, a circuit board 70 is fixed to the lower case 10, so that the hall element 71 is connected to the circuit board 70. With this configuration, the position of the circuit board 70 can be adjusted in circumferential and radial direction not to apply a stress to the terminal of the hall element 71. <P>COPYRIGHT: (C)2008,JPO&INPIT |
