摘要： A stator of an electric motor includes coil cores, bobbins and coils. The coil cores include six coil cores, which are arranged at equal angular intervals in a circumferential direction. The bobbins respectively cover outer peripheral surfaces of the coil cores, and the coils are respectively wound around outer peripheral surfaces of the bobbins. Among the six coils, each diametrically opposed two coils are electrically connected to each other through the corresponding connection line. Positioning members displace positions of the connection lines from one another, so that interference between the connection lines and interference between the connection line and the coils are limited.

摘要： A fluid pump includes a motor portion that has a stationary part and a rotator. The inner circumferential periphery of the stationary part and the outer circumferential periphery of the rotator define a fuel passage therebetween. The rotator is rotatable around the inner circumferential periphery of the stationary part. The motor portion drives a pump portion for pumping fuel through the fuel passage. The rotator includes a permanent magnet that is formed by injection molding a composite material containing a magnetic material and resin. The permanent magnet has one end with respect to the axial direction of the permanent magnet. The one end defines an axial end surface. The axial end surface has an injection port mark.

摘要： A fluid pump includes a stationary part. A rotator is rotatable around the inner circumferential periphery of the stationary part. One of the stationary part and the rotator includes at least one coil that generates magnetic force between the stationary part and the rotator for rotating the rotator when being supplied with electricity. A pump portion is provided to one axial end of the rotation axis of the rotator. A cover covers the other axial end of the rotation axis of the rotator and the stationary part. The cover defines an outlet passage through which fluid is discharged from the pump portion. The cover has a bearing hole that rotatably supports the other axial end of the rotation axis. The bearing hole has a closed bottom. The cover has a communication passage that communicates the outlet passage with the bearing hole.

摘要： A fluid pump includes coils that generate magnetic poles in the inner circumferential periphery of the stator core when being supplied with electricity. The magnetic poles are switched by controlling electricity supplied to the coils. The outer circumferential periphery of the rotator defines magnetic poles different from each other with respect to the rotative direction. The outer circumferential periphery of the rotator is opposed to the inner circumferential periphery of the stator core. A pump portion has a rotor member, which is rotated by the rotor member for pumping fuel. A housing has a pump housing portion and a motor housing portion. The pump housing portion surrounds the outer circumferential periphery of the pump portion. The motor housing portion defines an accommodating portion that surrounds the outer circumferential periphery of the stator core. The motor housing portion is dented radially inwardly with respect to the pump housing portion.

摘要： A fuel pump includes a stator core that has teeth being circumferentially arranged. Coils are formed by concentrically winding a wire around each of the teeth. The coils circumferentially generate magnetic poles in inner circumferential peripheries of the teeth when being supplied with electricity. The magnetic poles being switched by controlling electricity supplied to the plurality of coils. A rotator has an outer circumferential periphery opposed to the inner circumferential peripheries. The outer circumferential periphery defines magnetic poles different from each other with respect to a rotative direction thereof. A pump portion that has a rotor member rotated by the rotator for pumping fuel. An electrically insulative resin material is charged between the teeth, which are circumferentially adjacent to each other, thereby being molded such that the electrically insulative resin material covers the plurality of coils.
