<P>PROBLEM TO BE SOLVED: To provide a motor improving cooling performance with respect to a control substrate without occurrence of deformation and bend in the control substrate and to provide a pump with the motor. <P>SOLUTION: The motor is provided with a stator 3, a rotor 2, the control substrate 4 controlling conduction of the motor, a frame 12 having a storage chamber 16 storing the stator 3 and the control substrate 4, projections 5 projected into the storage chamber 16 and a heat conducting member with which the storage chamber 16 is filled as a filler 6. The control substrate 4 is provided with a semiconductor device 41. A radiating face of the semiconductor device 41 is confronted with the projection 5 by faces, and a gap between the two confronted faces is filled with the filler 6. The control substrate 4 is not directly brought into contact with the frame 12 and the projection 5, thereby applying stress to the control substrate 4 and preventing the occurrence of deformation and the bend. Also, cooling performance can be improved by the projection 5. Further, the motor is arranged in the pump 1, thereby preventing the deformation and the bend of the control substrate 4 and also improving the cooling performance. <P>COPYRIGHT: (C)2011,JPO&INPIT |
