TH175816A - Electric pump - Google Patents

Abstract

It has revealed electric pumps (100) with pump bodies (1) and electric motors (2) where the electric motor (2) consists of a rotating shaft (21), a cavity inside the motor (22) and a motor unit (23). ) Contained in the cavity inside the motor (22); The motor unit (23) consists of an internal stator (231) and an external rotor (232) .The external rotator (232) consists of magnetic steel (2321) and a support (2322) .The support (2322) is. The cylinder (1779a) is provided with a center hole and the center hole of the cylinder (1779a) extends outward to form a concave ring (2322b); The cylinder (2322a) is encased on the inner stator (231). Magnetic steel (1778) has been arranged between the walls. The inner ring of the cylinder (2322a) to the outer wall of the inner stator (231) and magnetic steel (2321) is firmly connected to the inner ring wall of the cylinder (2322a) and the concave ring ( 2322b) is tightly encased at the rotating shaft (21), and the technical solution of This invention adopts the structure of the external rotor and the internal stator and has the advantages of small size, light weight and high efficiency. This reduces the raw material cost and the size of the electric pump.
