Title:
MAGNETIC FORCE DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2001/001551
Kind Code:
A1
Abstract:
A magnetic force drive device capable of providing a drive force such as a rotating movement or an axial movement using a magnetic force without depending on an external energy, comprising a main arm (1) and an auxiliary arm (2) respectively turnably supported on respective rotating shafts (10, 20), magnets (11, 12) being attached to the main arm (1), and magnets (21, 22) to the auxiliary arm (2). The magnets (11, 12, 21) have the same magnetic force of 1f, and the magnet (22) has 2f twice the above magnetic force. The rotation circumference of the magnet (11) circumscribes that of the magnet (22), and that of the magnet (12) circumscribes that of the magnet (21). When a magnet (M) compresses a magnetic force down to a magnetic force of 1f and then releases the compression, the magnet (12) pushes the magnet (21) with a force of about 1.7f to rotate the auxiliary arm (2) a half-turn, and then the magnet (22) pushes the magnet (11) with a force of 2f.
