The invention relates to the technical field of underwater power propellers, and particularly relates to an electromagnet and permanent magnet combined vector magnetic coupling propeller. As the types and operation types of underwater robots, ships and the like are more and more, the performance requirements of the underwater propellers are higher and higher, underwater equipment is soaked in water for a relatively long time, if the sealing performance of an underwater propeller is not good, equipment faults can be caused, underwater equipment cannot work normally, the service life of the underwater equipment is shortened, and the underwater permanent magnet coupling propeller for converting dynamic sealing into static sealing has the problems of low transmission efficiency, insufficient transmission power, single transmission power direction and the like due to the fact that a gap between inner and outer rotors is too large. In order to overcome the defects in the prior art, the electromagnet and permanent magnet combined vector magnetic coupling propeller suitable for underwater power vector propulsion is provided, magnetic coupling vector propulsion is achieved through the steering engine, and a gap energy loss generated during magnetic coupling vector propulsion is compensated through the electromagnets.
Description
technical field [0001] The present application relates to the technical field of underwater power propellers, in particular to a vector magnetic coupling propeller with electromagnetic permanent magnet combination. Background technique [0002] The underwater power unit is generally driven by a motor to generate propellers to generate thrust so that underwater equipment can be powered. One of the important technologies of underwater thrusters is sealing technology. Although the dynamic sealing method is simple in structure, there are problems such as unreliable sealing and the need to replace the sealing ring regularly. Therefore, underwater thrusters generally do not use this method to solve the problem of dynamic sealing. A good way is magnetic coupling. The magnetically coupled thruster is generally composed of a motor, a motor driver, an inner rotor, an isolation sleeve and an outer rotor, which can realize the conversion of dynamic seal transmission power to static sea...
