Abstract: A drive controller that controls a drive of a motor. The drive controller performs a collision force moderation control during a motor start time, during which a collision force in a collision between a shaft outwall with an impeller hole inwall for a positioning is moderated, by changing a power supply at a stage transition time of transiting from a position detection to a position determination. The maximum value of a first output value during a position detection time is set to be greater than a first threshold that at least causes a rotation number of the motor to yield a detectable induction voltage. A second output value during a position determination time is set to be lower than a second threshold that causes a wear or a breakage of an impeller by the collision force.

Abstract: Relay terminals, which are formed integrally with a W-phase terminal, a V-phase terminal and a U-phase terminal provided radially outside bobbins, connect stator coils and the W-phase terminal, the V-phase terminal and the U-phase terminal. Second connection parts of the relay terminals connected to the coils are provided radially inside the W-phase terminal, the V-phase terminal and the U-phase terminal. Thus distances between the second connection part and the inner wall surface of a housing are increased to maintain insulation between the relay terminals and the housing. Thus the relay terminals are protected from breakage.

Abstract: A fuel pump has a motor portion and a pump portion, wherein fuel is sucked from an inlet port into the pump portion when an impeller is rotated and the pressurized fuel is discharged out of the fuel pump from an outlet port. A stator has multiple stator cores on which respective stator coils are wound to form a star-connection winding. A terminal sub-assembly is provided hi an axial side portion of the stator. The terminal sub-assembly has multiple conductive members and each end portion of the stator coils is respectively connected to connecting portions of the conductive members, which are arranged at equal intervals in a circumferential direction of the terminal sub-assembly.
