| Summary: | Aiming at the water tightness problem of underwater robot thrusters, it is proposed that permanent magnetic thrusters convert dynamic seals into static seals to solve the leakage problem The electromagnetic finite element method was used to study the influence of the torque, slip, and material of the isolation sleeve on the transmission performance of the disc and barrel permanent magnet thrusters, and an experimental platform was built to verify the performance The transmission capacity is 57N·m, while the disc structure is only 148N·m; when the internal and external magnetic sleeve angles are 0°, 15° and 45°, and the slip is 800r/min, the eddy current loss of the aluminum alloy isolation sleeve can reach the titanium alloy isolation 46~47 times of the sleeve; when the experiment proves that the rated slip is 800r/min, the maximum torque transmission of the cylindrical structure is 463 N·m, which meets the torque demand of the working condition, that is, the cylindrical synchronous permanent magnet thruster with a titanium alloy isolation sleeve It has strong torque transmission ability and does not lose rotation It is more suitable for underwater robot applications |
