Problems solved by technology

[0002] The magnet and the impeller of the brushless DC magnetic drive pump are injected into one body to form the rotor of the motor. There is a sleeve in the middle of the rotor, which is fixed in the housing through a high-performance ceramic shaft. The stator and the circuit board of the motor are potted with epoxy resin glue. In the pump body, the original water pump has the defect of medium leakage, and the waterproof effect is not good, which affects the use of the motor

Abstract

The invention discloses a brushless direct-current magnetic isolation type water pump which comprises a motor body, a pump head and a pump base. The pump head is installed on the pump base. The pump base and an outer magnet rotor are arranged on the motor body. The outer magnet rotor is installed between the motor body and the pump base and completely sealed in the pump base. A plurality of pieces of outer rotor magnetic steel are pasted in the outer magnet rotor in the N-S sequence. An impeller is installed on the pump base and provided with inner rotor magnetic steel with the polarity distributed in the N-S sequence. The number of the pieces of the outer rotor magnetic steel is eight. The brushless direct-current magnetic isolation type water pump is simple in structure, reasonable in manufacturing, amphibious and high in effect, and the leakage problem can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a brushless DC magnetic isolation water pump. Background technique [0002] The magnet and the impeller of the brushless DC magnetic drive pump are injected into one body to form the rotor of the motor. There is a sleeve in the middle of the rotor, which is fixed in the housing through a high-performance ceramic shaft. The stator and the circuit board of the motor are potted with epoxy resin glue. In the pump body, the original water pump has the defect of medium leakage, and the waterproof effect is not good, which affects the use of the motor. Contents of the invention [0003] In order to solve the above problems, the present invention provides a brushless DC magnetic drive pump with simple structure, reasonable design, safe and reliable use. [0004] In order to achieve the above object, the present invention is achieved through the following technical ...
