Claims

[Scope of utility model registration request]

A pump casing having a suction pipe and a discharge pipe, an impeller rotatably supported inside the pump casing, a magnet annularly provided on the impeller, and a yoke and a coil provided on the pump casing side. In the cascade pump with a built-in motor, the magnet is arranged so that the same polarity portion appears on the end face of the impeller, and the winding direction of the coil wound around the yoke is perpendicular to the direction of the magnetic field generated by the magnet. A cascade pump with a built-in motor, characterized in that the winding surface of the coil is arranged so that the lines of magnetic force are included in parallel.
