Abstract
An electromagnetic vibratory exciter for use in vibratory equipment incorporates a free mass housed in an elongate housing having electromagnets mounted inboard at each end of the housing. The free mass is totally enclosed and carries a pair of armatures for cooperation with the electromagnets. An air gap is maintained during operation between the electromagnets and the armatures through the use of compression elements interposed between the electromagnet housing and the armatures of the free mass.
