部の空冷構造。 The pump section and motor section are separated liquid-tightly by a partition wall,
In the motor part, a cylindrical drive magnet is attached to a support that is integral with the rotor shaft, and in the pump part, a cylindrical driven magnet equipped with an impeller is installed concentrically inside the cylindrical drive magnet. In a magnet-driven pump arranged in A fan structure is formed by disposing a partition plate extending from the peripheral surface toward the center of the rotor shaft, and an intake hole is formed in the rear end surface of the motor casing via the stator assembly and the rotor assembly. At the same time, an exhaust hole is formed in the circumferential surface of the motor casing facing the outer peripheral edge of the fan blade, and as the support body rotates, air flows into the motor casing through the intake hole and the stator assembly and An air-cooling structure for a motor section in a magnet-driven pump in which the flow flows near a rotor assembly and flows out from the exhaust hole.
