Abstract:
1. An electric variable inertia apparatus comprising: a housing assembly having a cover assembly mounted securely on the open front of the housing and having a servo drive device to provide a variable rotatory driving force, being an external motor mounted in the housing between the base and the cover and having a planetary gear mechanism mounted in the housing between the external motor and the cover and having a load assembly being a flywheel connected securely to the rear end of the rotated shaft of the sun gear assembly and rotating simultaneously with the rotated shaft to generate rotational inertia; whereby, by controlling the servo drive device connected with the ring gear at a specific rotational velocity according to the rotational velocity of the planetary frame connected to the external input device, the load assembly is rotated to generate a widely ranging rotational inertia to react to the external input device.
