(5 4)#H0) 9i--I&Y E /; := 
(57) Abstract: This rotary device is provided with: a first 
disk-shaped rotor that can rotate about a first rotation axis; 
a plurality of first permanent magnets that are aligned on an 
w4/ outer circumferential section of the first disk-shaped rotor 
such that the N and S poles alternate; at least one pair of elec
40A 30 tromagnets that are arranged with a predetermined gap from 
i 40A a static position near the plurality of first permanent magnets; 
40B and a pair of sensor switches that each sense the rotating po
sitions of the N and S poles of the first permanent magnets 
0 and cause the at least one pair of electromagnets to be ener
N/, gized. The present invention is configured to rotate the first 
10 disk-shaped rotor in such a manner that one of the pair of 
I"N electromagnets is energized on the basis of the sensing results 
of the pair of sensor switches, and each of the first permanent 
magnetsare moved in a predetermined direction due to the 
6A attractive force and the repulsive force to/from the first per
S(G) /Amanent magnet near the energized electromagnet.
