Summary:PROBLEM TO BE SOLVED: To make size reduction in the radial direction, without causing magnetic characteristics to deteriorate. SOLUTION: The end sections of windings 27 are led out in the axial direction via groove sections 28a and 28b formed to a peripheral section, in the axial direction of a coil bobbin 21, and are connected to a control board 11 for controlling an electric conduction through the windings 27 via the notched section 26 of a core member 23a. Accordingly, since the windings 27 are led out in the axial direction of a motor, the sizes in the radial directions of the motor and a pump can be reduced. The deterioration of the magnetic characteristics of a stator is prevented by increasing a magneto-resistance, and the motor having high performance can be obtained. COPYRIGHT: (C)2010,JPO&INPIT
