Description
Technical Field
The invention relates to a deepwater propulsion motor, in particular to a water pressure resistant structure of the deepwater propulsion motor.
Background
Electric motors for propulsion in deep water are often required to have resistance to water pressure and water penetration. At present, two conventional structural modes adopted by the motor with the functions are as follows: one is to encapsulate special resin into the deep water propulsion stator to fill the cavities and gaps inside the stator winding, between the end and the machine base, so as to achieve the effect of sealing the stator, and make the motor stator become a solid entity to balance the water pressure outside the motor; the second is to directly charge the motor with oil with pressure, and balance the water pressure of deep water outside the motor by adjusting the compensation oil pressure. For the first structural form, special equipment and special resin are needed for filling, the filling is compact, no fine air holes exist, the current filling process is not mature, and a good filling effect cannot be achieved; for the second structural form, the sealing of the motor rotating part is difficult, the sealing is easy to wear, the phenomenon of oil leakage easily occurs under high pressure in the deep sea, the environment protection requirement is not met, the service life of the sealing element is limited, and the sealing element needs to be replaced periodically to supplement pressure oil. When the rotor rotates at a high speed, the uneven winding end face forms larger oil resistance, and the motor efficiency is affected. The existing sealing structure is not scientific and reasonable, and cannot meet the working requirements of the deepwater motor.
