| PROBLEM TO BE SOLVED: To provide an electric pump and an electric pump mounting structure, which reduce the size in the radial direction and the space of a mounting face by dispensing with flanges for installation, reduce the number of components and simplify the installation by dispensing with bolts for the installation. SOLUTION: The electric pump 10 includes: a second housing 60 and a first housing 62 separated from each other in an axial direction; a stator part 20 accommodating an annular coil part 22; an outer rotor part 30 driven rotatively based on the magnetic field of the coil part 22 inside the housings; and an inner rotor 40 rotatably supported by a support shaft part 50 eccentric to the outer rotor part 30 and having an outer peripheral face engaged with the inner peripheral surface of the outer rotor part 30. The second housing 60 is press-fitted onto the support shaft part 50, to which the first housing 62 is fixed, from one side in the axial direction and catches the outer rotor part 30 and the stator part 20 from both sides in the axial direction.

| <P>PROBLEM TO BE SOLVED: To provide an electric pump suppressing inclination of a shaft and reducing size in an axial direction. <P>SOLUTION: A stator 50 includes a magnetic material portion 51, and forms a magnetic field by energization to a winding. A rotor 60 is rotatably arranged radially inward of the stator 50, and rotated by receiving the magnetic field formed by the stator 50 when energizing the winding. A shaft 70 is rotated integrally with the rotor 60. Bearing portions 35, 75 rotatably support the shaft 70. By rotation of the shaft, a pump section 12 sucks fluid from a suction port and delivers the fluid from a delivery port. Since the axial center of the first bearing portion 75 is positioned inside an internal area defined by both the axial ends of the magnetic material portion 51 of the stator 50, the inclination of the shaft 70 due to rotation can be suppressed. Also, the size in the axial direction can be reduced in comparison with the case of bearing by both the ends of the rotor 60. <P>COPYRIGHT: (C)2011,JPO&INPIT | ||||||

| PROBLEM TO BE SOLVED: To solve a problem that an electric element core is deformed, and the efficiency is lowered caused by the increase of iron loss, when the electric element manufactured by annularly bending a stator core obtained by laminating an iron core piece and joining the same, is shrinkage-fitted to a restriction shell. SOLUTION: The electric element manufactured by annularly bending the stator core obtained by laminating the iron core piece, is fixed to a rolled shell manufactured by rolling and joining a plate-shaped metal having the rigidity lower than that of the restriction shell, by the shrinkage-fitting or the press- fitting. The deformation of the electric element is prevented by fitting a joint part of the stator core to a joint part of the rolled shell, whereby the lowering of the efficiency can be inhibited.

| PURPOSE: To prevent a compressor from being cooled excessively and restrain generation of a drain and extend the life of lubricating oil and achieve energy saving and noise reduction by providing temperature sensors in a package and an oil separator portion, and stopping a ventilating fan or controlling the number of revolution of the fan below a specified temperature so as to control the amount of cooling wind. CONSTITUTION: A reference temperature is set in advance by a temperature sensor 11 for detecting the temperature of the discharge portion of a compressor 3 and ambient temperature or a relay, and when e.g. the temperature of the discharge opening is less than 70 to 75°C and the ambient temperature is less than 40 to 45°C a ventilating fan 10 is stopped or the number of revolution of the fan 10 is controlled. The amount of ventilation is thus controlled in order to prevent temperature lowering and realize efficient operation of the fan 10. In this case the ambient temperature of the compressor 3 takes precedence over the temperature of the discharge opening; when the ambient temperature is less than the reference temperature operation of the ventilating fan 10 is maintained even with the temperature of the discharge opening being less than the reference temperature and reliability of electric parts is thus maintained and the main body of the compressor 3 is prevented from being cooled excessively and generation of a drain is restrained and noise reduction is achieved.
