PURPOSE: A generator of alternating field and vibration is provided to maximize the vibration of stationary magnet in alternation by increasing the intensity of the alternating field and to solve the problem that the magnetic field in one part weakens when the phase rotates reversely due to alternation, by winding coils in the order of N-S-S-N-S-N. CONSTITUTION: A generator of alternating field and vibration is composed as follows: coils(2,12,22) which are reeled in the central area of a first rectangular bobbin(1), a second rectangular bobbin(11) and a third rectangular bobbin(21) in the longitudinal direction in order to form magnetic field parts(3,13,23) on both ends of each bobbin; NDF stationary magnets(31,32,33,34) which are arranged between each end of the first, second and third rectangular bobbins where magnetic fields are formed; and multiple cores which are inserted into the internal space of the first, second and third rectangular bobbins. |
