Abstract

The invention discloses a motor working underwater, comprising a non-metallic waterproof shell and an end cover fixedly connected with the shell. A sealed cylinder is formed in the center of the shell. A positioning column is formed on the inner bottom of the sealed cylinder. A motor stator is fixedly installed on the positioning column. The sealed cylinder is internally equipped with a driving circuit. A package body of hard waterproof sealant is formed at the mouth of the sealed cylinder. The motor stator and the driving circuit are sealed in the sealed cylinder by the package body of hard waterproof sealant. The coil lead of the motor stator passes through the package body of hard waterproof sealant and extends to the outside of the sealed cylinder. The end cover is provided with a motor rotor support hole. A motor rotor matching the motor stator is supported on the outer circle of the motor rotor support hole and the sealed cylinder. The motor rotor is provided with a power output connection part of the motor. The motor of the invention has the advantages of simple structure, high resistance to high pressure, and easy use.
