Description

High waterproof motor for underwater Technical Field The utility model relates to the technical field of motors, in particular to a high waterproof motor for underwater use. Background The hydrofoil driving motor is in long-term contact with water and even is submerged in water, and when the hydrofoil driving motor works, the motor needs to continuously output power in the water, so that the requirement on water resistance is extremely high. The sealing scheme of the hydrofoil driving motor needs to integrate material performance, structural design and working condition adaptability, and has the technical difficulty of balancing sealing reliability, cost, maintenance complexity and environmental adaptability. With the development of deep sea exploration and marine equipment, a high-reliability sealing technology is one of the core research directions of an underwater power system.
