Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a thin DC brushless motor which can secure the stability of the performance and vibration/noise level thereof, improve the efficiency thereof, and reduce the number of components and assembly man-hours, and to provide a seal-less pump using the DC brushless motor. SOLUTION: This DC brushless motor has a board 10 fixed to a center of a stator core 1. The board 10 has a center board 10a and an arm board 10b which extends from the center board 10a to a salient pole 2 and falls into a space between winding coils 4. A drive IC 9 is mounted on the center board 10a, and a pole position sensor 8 is mounted on the arm board 10b. COPYRIGHT: (C)2003,JPO
