A machine includes a piston disposed in a housing and configured to reciprocate in the housing. At least one valve is coupled to the housing. A magnetically-geared valve actuation system is coupled to the at least one valve. A plurality of sensors is configured to detect a plurality of parameters related to the machine. A control system is coupled to the plurality of sensors and the magnetically-geared valve actuation system. The magnetically-geared valve actuation system is configured to actuate the at least one valve in response to reciprocation of the piston in the housing, signals originating from the sensors or control system, or combinations thereof.
