  • Patent number: 5144176
    Abstract: An electromagnetic vibrating motor requires certain criteria to perform its functions. Such criteria include: achieving high amplitudes from the driven motor when compared with the relatively restricted active gap of a simple electromagnet, the amplitude of the driven member should be unaffected by weight variations or changes in resiliently constraining forces, it should have a stationary member for suspending the system without imparting substantial vibrations to the vicinity, and it should be easily connected to driven member of the system. The present invention includes three masses. The first mass is a driven mass, the second mass is an electromagnetic member and the third mass is a magnetic member. These masses are connected together through springs in order to perform its necessary functions while meeting the required criteria.
