Title:
A PERMANENT MAGNET SYNCHRONOUS MOTOR FOR A DISCHARGE PUMP
Document Type and Number:
WIPO Patent Application WO/2009/018707
Kind Code:
A1
Abstract:
A permanent magnet synchronous motor for a discharge pump is provided, which
comprises a permanent magnet rotor (2) driving an impeller (1) to rotate, a pump
body (3) supporting the permanent magnet rotor (2), a stator core (5) and a stator
coil (4) which winding is aluminum enameled wire winding that is sealed in a container
(10). The stator coil (4) winding and especially a leading-out welding part (9)
in the permanent magnet synchronous motor for a discharge pump are sealed by plastics
or epoxy resin, thereby the stator coil winding and the leading-out welding part
(9) are separated from the ambient air and especially the wet air, and theproblems
of the oxidization and corrosion of the aluminum enameled wire winding and welding
part (9) are solved and the application of the aluminum enameled wire to the permanent
magnet synchronous motor for a discharge pump is realized.
