Other AbstractBased on traditional DC brushless motor, the disclosed structure integrates pressure compensation device with main body of electrical motor. The pressure compensation device is composed of up capping, spring, piston, contact switch, and body case of electrical motor. Being installed inside of the body case, the piston and the case form clearance fit. Spring is installed between the piston and the up capping. Being inside the motor, the contact switch is under the piston. The structure is capable of detecting and controlling running state of electrical motor, and ensuring sealing performance of electrical motor underwater operational environment. Advantages are: almost no limited depth of underwater operation, reliable performance of underwater electrical motor, compact structure, low failure rate, and good security. The invention is applicable to underwater robot, underwater operation tools and relevant industries of aquatic product.
