The present disclosure provides an axial engagement-controlled variable damper comprising a rotor assembly coupled to a rotor shaft and disposed about an axis of rotation and a stator, coaxially aligned with the rotor assembly. The axial engagement-controlled variable damper may further comprise a flux sleeve, axially movable relative to the rotor assembly between at least a first position and a second position. The flux sleeve may comprise a circumferential flange portion disposed radially between the rotor assembly and the stator, and may be configured to alter magnetic coupling between the stator and the rotor assembly in response being moved axially. The axial-engagement controlled variable damper may be configured to generate a first drag torque in response to the flux sleeve being in the first position and a second drag torque in response to the flux sleeve being in the second position.

A resonant motor system having a resonant circuit that includes magnetic coils and of capacitors, for generating an electric power when the resonant lot is rotated by an engine, a regenerating portion for the resonant motor, a motor driving portion, a motor control portion, and a capacitor portion for storing therein the electric power generated by the resonant motor when the resonant motor is regenerated, the resonant rotor being driven by the electric power stored in the capacitor portion when the engine is assisted by the resonant motor.

A moving body and a transport body are decelerated in a deceleration section by a deceleration mechanism. The deceleration mechanism includes a moving body that has moving body magnets and that moves on an air flow path while receiving an air flow, a transport body that has a magnetic material (transport body magnets or a transport body magnetic material repelling or attracting the moving body magnets and that is transported on a transport path in conjunction with the moving body on the basis of a magnetic force acting between the moving body magnets and the magnetic material, and braking means that is arranged in a deceleration section on the air flow path and that decelerates the moving body. The braking means includes an electric conductor in which an eddy current is generated due to movement of the moving body magnets.
