Abstract
An engine mount actuator having an upper casing open at one end, and connected at an opposite end to an engine mounting bolt. The engine mounting bolt extends within the casing and is supported by a bushing which is in turn laterally supported by an elastomeric isolator disk within the upper casing. A lower casing including a frame mounting bolt at one end, and opened at another end faces the opened end of the upper casing. A mounting flange is supported between the upper and lower casing open ends supports a stator, having first and second toroidal windings which define a circumferential space. A circumferential magnet assembly includes a permanent magnet means supported within the circumferential space, and is coupled to the engine mounting bolt through a spherical bearing. The magnet assembly produces a force against the engine mounting bolt in response to a current through the first and second toroidal windings. Counter vibratory forces may therefore be applied to the engine mounting bolt for suppressing vibrations from being transferred to the frame.
