Involute Jet Pump

Abstract

An involute jet pump includes a spiral blade, a permanent magnet cylinder rotor having a plurality of magnetic poles and a stator armature. The rotor is a hollow ring body and fastened at an outside of the spiral blade. Magnetic fields of adjoined magnetic poles are different. The stator armature is disposed at an outside of the rotor. The stator coil has rotating magnetic field after electrifying, and the magnetic field of the stator can be electrically modulated. The rotor drives the spiral blade for rotating due to modulated rotating magnetic field of the stator. The rotor embedded with the spiral blade is placed inside the stator armature. The whole volume of the involute jet pump can be effectively reduced. A magnetic field induction generated between the rotor and the stator drives the rotor embedded with the spiral blade for rotating.
