The invention discloses a permanent magnet rotor of an axial flow pump, which is fixed on a rotating shaft, and the two ends of the rotating shaft are respectively connected with the housing and the cover through bearings; one end of the rotating shaft near the outlet port is fixedly connected with an axial flow water wheel; the axial flow water wheel includes a fixed ring fixed with the rotating shaft, a movable ring sliding with the rotating shaft, and a movable ring connected with the rotating shaft. Multiple elastic blades between the fixed ring and the movable ring; There are also many U-shaped memory alloy sheets connected between the fixed ring and the movable ring; When the temperature in the shell is lower than the first set temperature, the memory alloy sheets are in the state of two ends close to each other, at least the outer end of each elastic blade is perpendicular to the axis of the rotating shaft; When the stator coil and the heating coil are electrified, the temperature in the shell is high. When the second setting temperature is set, the memory alloy sheet is in the state of being far away from each other at both ends. The memory alloy sheet is used to control whether the axial flow turbine is in working state or not according to the temperature, thus simplifying the structure of the control circuit.
