An electromagnetic vibrating exciter for use in vibratory equipment incorporates a free non mass housed in an elongated 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 airgap is maintained during operation between the electromagnet and the armatures through the use of compression elements interposed between the electromagent housing and the armature of the free mass. |
