FIELD: electricity.
SUBSTANCE: synchronous motor with permanent magnets with a built-in pump housing comprises a rotor assembly, a stator assembly comprising a winding wound on the frame and a core installed in the winding that is sealed by the winding sealing part, and a pump housing part that is formed by performing die-casting process on the basis of the stator assembly. The pump housing part comprises a cylinder for the rotor formed by performing die-casting process on the basis of the core and having a cavity for positioning the rotor assembly and an insulating thin layer formed by performing die-casting process on the arched part of the core pole for core insulation from the cavity for the rotor.
EFFECT: improved heat dissipation and reduced vibration noise.
