A rotary magnetic propeller

Abstract

The invention discloses a rotary magnetic thruster, which belongs to the field of electromagnetic technology. The invention includes a casing, a static magnetic pole, a moving magnetic pole, a push rod and a drive circuit. The static magnetic pole includes a magnetic circuit ring and a coil. The axial direction of the ring runs through, and a group of coils are arranged in two adjacent coil installation slots, and the same-named ends of the two sets of coils opposite to each other on the magnetic circuit ring are connected; the moving magnetic pole includes a permanent magnet ring, and the The direction of magnetic flux is the diameter direction of the permanent magnetic ring; the propulsion rod is provided with a spiral track that matches the ball at the mouth of the shell; every two groups of coils connected with the same end have an independent control of the current direction of the two groups of coils and Current on and off drive circuit. The invention can realize the continuous propulsion of the moving magnetic pole, the thrust is not limited by the distance, the propulsion process is reversible, the power consumption is low, the effect of the electromagnetic force is fully utilized, and a small current can generate a large force.

Description

technical field [0001] The present invention relates to a magnetic thruster, more particularly, to a rotary magnetic thruster. Background technique [0002] Common propellers include pneumatic propellers and electric propellers, and electric propellers are divided into motor drive and electromagnetic drive according to the driving mode. The motor-driven thruster generally needs to be decelerated by a gear reducer to push the propulsion rod to move, so that the rotational motion of the motor can be changed into a linear motion, and the forward and reverse rotation of the motor is used to complete the push rod action. It is suitable for long-distance and slow-moving occasion. Electromagnetically driven thrusters generally use the attraction and repulsion of magnetic poles to realize the movement of the propulsion rod. Since the thrust of existing electromagnetically driven thrusters is inversely proportional to the square of the distance, the thrust will be significantly redu...

Problems solved by technology

In this application, the magnitude of the thrust is inversely proportional to the square of the distance. When the stroke distance is long, the thrust will be significantly reduced, and it can only be applied to occasions where the propulsion distance is relatively short.
