Title: ELECTRIC PUMP
Abstract:
Disclosed is an electric pump (100), having a pump body (1) and an electric motor (2), wherein the electric motor (2) comprises a rotating shaft (21), a motor inner cavity (22), and a motor unit (23) contained in the motor inner cavity (22); the motor unit (23) comprises an inner stator (231) and an outer rotor (232), the outer rotor (232) comprises a magnetic steel (2321) and a support (2322), the support (2322) is of a cylinder (2322a) which is provided with a centre hole, and the centre hole of the cylinder (2322a) protrudes upward to form a convex ring (2322b); the cylinder (2322a) is sheathed on the inner stator (231), the magnetic steel (2321) is arranged between an inner ring wall of the cylinder (2322a) and an outer side wall of the inner stator (231), and the magnetic steel (2321) is fixedly connected to the inner ring wall of the cylinder (2322a); and the convex ring (2322b) is tightly sheathed on the rotating shaft (21). The technical solution of the invention adopts the structure of an outer rotor and an inner stator, and has the advantages of small volume, light weight and high efficiency, thereby greatly reducing material costs and the volume of the electric pump.
