Performance of Cableless Magnetic In-Piping Actuator Capable of High-Speed Movement by Means of Inertial Force

الملخص EN

The present paper proposes a novel cableless magnetic actuator with a new propulsion module that exhibits a very high thrusting force.

This actuator contains an electrical inverter that directly transforms DC from button batteries into AC.

The electrical DC-AC inverter incorporates a mass-spring system, a reed switch, and a curved permanent magnet that switches under an electromagnetic force.

The actuator is moved by the inertial force of the mass-spring system due to mechanical resonance energy.

The experimental results show that the actuator is able to move upward at a speed of 19.7 mm/s when using 10 button batteries when pulling a 20 g load mass.

This cableless magnetic actuator has several possible applications, including narrow pipe inspection and maintenance.
