Abstract

The invention discloses an underwater propeller, which comprises a stator, a rotor and a propeller. The rotor surrounds the stator, and the propeller is arranged on the outer wall of the rotor. The stator comprises a casing and a three-phase electric wire winding arranged in the casing, wherein an anti-corrosion material is injected into the casing; A permanent magnet is embedded in the inner wallof the rotor. By adopting the structure, the invention can simplify the structure of the underwater propeller, reduce the volume of the underwater propeller, and solve the problem of poor heat dissipation effect of the underwater propeller on the premise of guaranteeing the waterproof effect.

Description

technical field [0001] The invention relates to the technical field of power devices, in particular to an underwater propeller. Background technique [0002] The underwater propeller in the prior art is to put the motor in the sealed casing to achieve the effect of waterproofing. The propeller is fixed outside the sealed casing through the gear arranged on the motor drive shaft and exposed to water. The drive shaft of the motor passes through the sealing device. Realize the connection with the external propeller drive mechanism; when the motor is working, the motor transmission shaft rotates, and the propeller is driven to rotate through the gear to achieve the purpose of forward driving. [0003] However, since the motor device in the prior art needs to be waterproofed through the sealed casing and the sealing device, the structure of the entire underwater propeller is complicated and the volume is also large. The heat generated by the motor needs to be transferred through ...
