摘要： An electric pump for use with an engine in a vehicle is provided. The electric pump has an impeller having a plurality of blades for moving coolant. A working surface of each blade is formed to be a flat plane which extends generally straight in both an axial direction and a radial direction. The electric pump is formed by a centrifugal pump. When the electric pump is not operating and is used as a portion of a coolant passage, flowing resistance can be reduced as compared with a case where the working surface of each blade is curved.

摘要： A recording disk drive motor is disclosed which is employed in a recording disk drive that retains a removable recording disk that has a diameter of 30 mm or less, as well as a method of manufacturing a stator core used in the same. The core back of the stator core in the motor has an arc shaped inner circumferential surface therein that is offset from the center thereof. The stator core is produced from a laminated body having a stator core, a chuck frame that is integral with and surrounds the stator core, and connector arms that connect the stator core and the chuck frame and integral therewith. After the windings are wound around the stator teeth, the stator core is cut from each connecting arm and the stator core is removed from the chuck frame.

In the stator core stack, the linking portion is folded and deformed the linking portion so as to join an end surfaces of the straight core, and a core back outer peripheral portion is formed at the back side of the core back, and the diameter of the core back outer peripheral portion is formed same as or shorter than the diameter of the inner peripheral surface of the housing, and is disposed in the housing. A bar-like member is press-fitted in the axial direction between both the end surfaces of the straight core. In other example of motor, an engaging portion extending in the axial direction and projecting in the radial inward direction is formed in the inner peripheral surface of the housing, and the end surfaces of the straight core are engaged or fitted with the engaging portion.
