Beschreibung
Zusammenfassung:	The invention discloses a self-driven type motor pump. Theself-driven type motor pump comprises a pump shell with a pump cavity inside; a fixed shaft which penetrates through the pump cavity of the pump shell and is fixedly arranged; a stator assembly which is fixed on the fixed shaft; and a rotor assembly which comprises a rotating body surrounding the periphery of the stator assembly and a permanent magnet arranged on an inner ring of the rotating body. Alternating current is introduced into the stator assembly, an alternating magnetic field is generated through excitation, the alternating magnetic field acts on the permanent magnet to drive the rotating body to rotate in the pump cavity, and a hydraulic medium is sucked into/pumped out of the pump cavity. According to the self-driven motor pump, the alternating current is introduced into the stator assembly, an alternating magnetic field is generated through excitation, the alternating magnetic field acts on the permanent magnet to drive the rotating body
