Pump, refrigeration cycle device, and method for producing pump

The objective of the present invention is to provide a pump that can reduce the distance between a magnet and a stator and that can increase pump performance. In a rotor section (60a), a thermoplastic resin is used to integrally assemble: a magnet (402) formed in a cylinder; a first magnet holder (4...

More Information
Summary:The objective of the present invention is to provide a pump that can reduce the distance between a magnet and a stator and that can increase pump performance. In a rotor section (60a), a thermoplastic resin is used to integrally assemble: a magnet (402) formed in a cylinder; a first magnet holder (400) that holds end of the magnet (402) on a bladed wheel attachment section (67a) side; a second magnet holder (401) that holds the end of the magnet (402) on a magnetic position detection element (58b) side; a back yoke (403) disposed on the inside of the magnet (402); a sleeve bearing (66) disposed on the inside of the back yoke (403); and a position detection magnet (401) that is provided to the surface of the second magnet holder (401) at the reverse side from the magnet attachment side and that detects magnetic flux by means of the magnetic position detection element (58b). Simultaneously, the bladed wheel attachment section (67a) is formed from a thermoplastic resin.
