Description

A kind of electro-motor of underwater operation

Technical field

The utility model is related to field of ocean engineering, and in particular to a kind of electro-motor of underwater operation.

Background technology

Underwater motor on the market is all brushless motor at present, and shell, protecgulum and rear cover all use common metal, stator Got up with epoxy resin encapsulated, rotor also uses epoxy resin encapsulated, can there are problems that following 3 in this way：

1. the hard impurity such as silt easily enters inside motor, accelerate the abrasion of bearing, reduce bearing uses the longevity Life；Simultaneously because rotor and stator effective clearance are small, the relatively thin therefore sharp sand meeting of the embedding glue-line between rotor and stator This two layers of glue-line is ground away quickly, once glue-line destroys, stator core, rotor core, enameled wire and squirrel-cage bar all can be quickly It is corroded, motor performance is just substantially reduced or even run out of steam；

2. metal is exposed for a long time slowly to occur corrosion in water or in wet air, is rubbed or installed by silt When collision etc. cause the bare metals parts such as damaged shell, protecgulum, rear cover, axis, bearing and screw all can inevitably occur Corrosion phenomena will influence normal operation and the service life of motor once there is some part that corrosion occurs；

3. since the effective clearance between rotor and stator is small, the glue-line of two adjacent surfaces of rotor and stator is very thin, due to Winding high temperature or silt enter scratching and glue-line can be caused to fall behind glue-line gap, these glue-lines fallen can scratch other Glue-line, serious meeting directly stuck rotor, damages motor.
