Magnetic drive motor assembly and associated method of use
An input cam having a recessed track for establishing a desired dwell time for a plurality of rotatable permanent magnets and an output cam having a recessed track for maximizing the harnessing of linear motion energy and to apply the harnessed energy to a rotary output are provided to improve the efficiency of a magnetic transmission.
1. A camshaft arrangement for establishing a dwell time of a plurality of rotatable permanent magnets of a magnetic drive train, the camshaft arrangement comprising:
an input cam comprising a recessed track to engage a cam roller of a crank arm and further comprising one or more supports to attach the input cam to a reciprocating shaft, the reciprocating shaft to rotate a plurality of rotatable permanent magnets in response to a rotation of the crank arm that results in a reciprocating stroke of a shuttle comprising a plurality of fixed permanent magnets; and
wherein the recessed track of the input cam is dimensioned to establish a dwell time of the plurality of rotatable permanent magnets during the reciprocating stroke of the shuttle.
2. The camshaft arrangement of claim 1 , wherein the dwell time established by the recessed track of the input cam is sufficient to allow the shuttle to complete its reciprocating stroke.
3. The camshaft arrangement of claim 1 , wherein the dwell time established by the recessed track of the input cam provides for maximum magnetic alignment between the plurality of rotatable permanent magnets and the plurality of fixed permanent magnets of the shuttle during the reciprocating stroke of the shuttle.
4. The camshaft arrangement of claim 1 , wherein the plurality of rotatable permanent magnets are rotated 180° during each rotation of the crank arm.
5. The camshaft arrangement of claim 1 , wherein a velocity of the rotation of the plurality of rotatable permanent magnets is sinusoidal and the recessed track of the input cam provides for minimal movement of the cam roller at 90° and 270° positions of the recessed track.
6. The camshaft arrangement of claim 1 , wherein a width at 0° and 180° positions of the recessed track is substantially equal to a diameter of the cam roller, and wherein a width at 90° and 270° positions of the recessed track is substantially equal to a swing of the crank arm.
7. The camshaft arrangement of claim 1 , further comprising:
a crank shaft coupled to the crank arm; and
a continuous drive motor coupled to the crank shaft to provide the rotation of the crank arm.
8. The camshaft arrangement of claim 5 , wherein a width at 90° and 270° positions of the recessed track is substantially equal to a distance from a center of the crank shaft to an outside diameter of the cam roller.
