Abstract

A magnetic motor comprises a rotary shaft and a rotating disc coupled to rotate with the shaft. The rotating disc includes first, second and third magnets positioned at 120° intervals about the face of the disc. A pivotally mounted bracket is symmetrically positioned about the shaft and includes fourth and fifth magnets which are aligned to repel the first, second and third magnets when the magnet on the bracket is positioned adjacent to a magnet on the rotating disc. The bracket has a first position in which the fourth magnet is positioned close to the disc and the fifth magnet is positioned away from the disc. The bracket also has a second position in which the fourth magnet is positioned away from the disc and the fifth magnet is positioned close to the disc. An electrical solenoid is coupled by linkage to the pivotally mounted bracket and works in combination with a timing cam and an electrical switch to forecfully displace the bracket into the first position as one of the rotating magnets is passing the top dead center position and to forcefully displace the bracket into the second position as one of the rotating magnets is passing the bottom dead center position. The relative movement of the pivoting bracket with respect to the rotating disc impart a rotational force to the shaft.

Claims

1. A magnetic motor comprising:

(a) a rotary shaft;

(b) a rotating disc coupled to said shaft and having first, second and third magnets positioned at 120°

intervals about the face of said disc;

(c) a pivotally mounted bracket symmetrically positioned about said shaft and having fourth and fifth magnets aligned to repel said first, second and third magnets when positioned adjacent thereto, said bracket having a first position in which said fourth magnet is positioned close to said disc and said fifth magnet is positioned away from said disc, and a second position in which said fourth magnet is positioned away from said disc and said fifth magnet is positioned close to said disc; and

(d) means coupled to said bracket for forcefully displacing said bracket into the first position as one of said rotating magnets is passing the top dead center position and for forcefully displacing said bracket into the second position as one of said rotating magnets is passing the bottom dead center position, whereby a rotational force is imposed on said shaft.

2. The magnetic motor of claim 1 further including timing means coupled to said shaft for determining the rotational position of said magnets on said disc.

3. The magnetic motor of claim 2 wherein said displacing means further includes actuator means coupled to said timing means and to said bracket for displacing said bracket between the first position and the second position.

4. The magnetic motor of claim 3 wherein said timing means includes a cam coupled to said shaft.

5. The magnetic motor of claim 3 wherein said actuator means includes:

(a) an electrical solenoid coupled to said bracket and displaceable between first and second position;

(b) a source of electrical power;

(c) means coupled to said solenoid, to said source of electrical power and to said timing means for energizing said solenoid when the magnets on said disc and said bracket are properly aligned.

6. The magnetic motor of claim 5 wherein said energizing means includes a switch actuated by said timing means.

7. The magnetic motor of claim 5 wherein said solenoid includes:

(a) a shaft;

(b) a body; and

(c) means for extending and retracting said shaft with respect to said body.

8. The magnetic motor of claim 7 wherein said extending and retracting means includes an electromagnet.

9. The magnetic motor of claim 7 wherein said extending and retracting means includes:

(a) an electromagnet for retracting said shaft with respect to said body;

(b) a spring for biasing said shaft to the extended position.

10. The magnetic motor of claim 5 wherein said source of electrical power includes a battery.
