A tracked external rotor magnetic motor utilizing axial closed-circuit and open-circuit magnetic fields is disclosed. An axially magnetized annular planetary permanent
magnet attracts the inner edge of a pressure-bearing elliptical steel track, creating two radial
magnetic potential angles on the upper and lower sides of the track's inner edge. At the lower angle, the side poles of the annular permanent
magnet are attracted by opposite-pole permanent magnets, resulting in a closed
magnetic field that eliminates the magnetic force on the track, causing it to follow the
magnet's movement. At the upper angle, the side poles of the annular permanent magnet have an open
magnetic field, causing the permanent magnet roller to rotate under the radial
magnetic potential, driving the output gear ring wheel. This closed-circuit
magnetic effect forms the rotational cycle. This device not only increases the output
power density but also compensates for the high friction,
power loss, and
noise associated with planetary rotation mechanisms. It can be widely applied in transportation, energy construction,
energy conservation, and
environmental protection. Its simple mechanical structure and manufacturing process make it valuable for broad industrial and commercial applications.
