It is an advantage of the invention that:
1. the configuration of the present invention is simple, handling ease, of low cost;
2. heat can quickly be conducted to shell by having insulating oil in integrated waterproof case and spill into water by the present invention
In, effective protection stator sleeve group is burnt out because of high temperature;
3. present invention sealing allows inside motor also water-filling by limbers, while also having insulating oil in seal cavity, in this way
Design break the mode that is fully sealed of tradition, allow rotor and stator independent work, rotor allowed to enter in water, allow motor energy in this way
The pressure for bearing bigger, into deeper waters.
4. present invention manufacture is easy, easy to assembly, stable structure is durable.
Other than objects, features and advantages described above, the present invention also has other objects, features and advantages.
Below with reference to figure, the present invention is described in further detail.
