||Opposing Piston Magnet Motor
In the case of the Opposing Piston Motor, the
force upon the rotor (crankshaft) is in large part supplied by the attraction
force of permanent magnets. These permanent magnets and their holders make up
the pistons which are attracted to each other and to the coil core.
coil is placed between each set of magnetic pistons. The core of the coil is ferric
material to which the pistons are attracted. These pistons are oriented so that
the North and South poles are facing each other. As the magnetic pistons are
attracted and drawn towards each other they become closer to the coil between
In a conventional motor, the magnetic fields are at register only at one point in the rotation of the armature. The axial force between two magnets is much greater than the tangential force. The Opposing Piston Motor takes advantage of this axial force by facing the magnets to each other at register moving through a common axis. This applies to the attraction of the two pistons as well as the repulsion. The Opposing Piston Motor uses the coil to repel two magnets and uses two magnets to simultaneously attract to the core of the coil and to each other.
When the magnetic pistons are at their closest proximity to the coil core, the timing circuit is closed and a current pulse is
delivered to the coil. The coil is wired such that the current flow creates an
opposing magnetic field to that of the magnetic pistons. This works to offset
the magnetization induced in the core. The coil reduces the field induced in
the core, and can even overcome it and provide repulsion at sufficient voltage.
The magnetic pistons gain kinetic energy while being attracted to the stator
core and the next set of pistons are attracted towards the coil. Consequently,
the current applied to the coil cancels out the drag back of the pistons to the
coil core and the pistons are free to move away from the coil using the
remaining inertia gained in the attraction stage and the momentum of the
crankshaft and flywheel. The next set of pistons is attracted toward the coil
and the process is repeated.
The two cylinder motor is comparable to a simple two-pole motor that is used primarily for instructional purposes. Since the motor has only two cylinders, it operates rather roughly and does not provide too much torque. Additional coils and pistons must be added to the motor for it to become useful for industry.
As the magnets move toward the coil they induce a current in the coil which is opposite that of the current which repels the magnets.
