Abstract
An alternating-current permanent magnet drainage pump includes a pump cover, a pump body, a magnetic core, a rotating shaft, a stator core and coils. The coils are wound around a coil former, and the stator core is assembled to the coils. The pump body is a shell formed by surrounding a contour of the coils, the coil former, and the stator core which have been assembled to perform an integrated injection molding. The shell defines a magnetic core accommodating space used for accommodating the magnetic core and having an opening at a top portion. The magnetic core accommodating space extends from the opening to a center of the pump body. A supporting member is arranged in the opening at the top portion of the magnetic core accommodating space for supporting a bearing of the rotating shaft.
