A diaphragm pump configuration may include an eccentric drive assembly that is configured to be actuated by a motor shaft of a motor including an external magnetic rotor and an inner electrical stator that is contained in the external magnetic rotor. Two bearings may rotatably support the motor's drive shaft such that one bearing is positioned on one side of the eccentric drive assembly, and the other bearing is positioned on the other side of the eccentric drive assembly. The diaphragm pump configuration decreases considerably the workload on the bearing nearest to eccentric drive assembly, and significantly increases the operation time of the diaphragm pump.

A electromagnetic motor enhancement system includes an internal combustion engine that has a plurality of pistons, at least one cylinder head and an ignition control module. Each of the pistons is selectively urged in an upstroke and a downstroke. A plurality of magnets is provided and each of the magnets is coupled to an associated one of the pistons. An electromagnetic unit is coupled to the internal combustion engine. The electromagnetic unit is electrically charged in a first polarity when the pistons are urged in the upstroke. Thus, the magnet corresponding to each of the pistons is attracted to the electromagnet unit. The electromagnetic unit is electrically charged in a second polarity when the pistons are urged in the downstroke. Thus, the magnet corresponding to each of the pistons is repelled from the electromagnetic unit.

Multiple arrays of linear motors and generators are combined in a radial configuration to provide high mechanical efficiency to deliver power in a single plane of motion to a common crankshaft. Magnet core assemblies for the motors and generators use powerful rare earth magnets positioned within an outer flux containment shell comprising a highly-magnetically-permeable ferrous-alloy to provide high power density. The motor magnet stack is attached directly to a link rod that connects to the crankshaft. Pulsed power is provided to electromagnetic coils coils by microcomputer control, and coil energy is recovered at the ends of the linear stroke. A controller energizes the coils in certain combinations of coil location and polarity in order to produce bi-directional mechanical motion. Energy that is released when coils are switched off is harvested as voltage pulses returned to standby batteries or capacitors, or the electrochemical cells.
