MOTOR HAVING RECIPROCATING AND ROTATING PERMANENT MAGNETS
First Claim
Patent Images
1. A motor comprising:
- a rotor supported for rotation about an axis;
a first pair of rotor magnets supported on the rotor, including a first rotor magnet and a second rotor magnet spaced angularly about the axis in an opposite radial direction from the first rotor magnet such that the first pair of rotor magnets rotate about the axis along a path having an outermost circumferential perimeter;
a first reciprocating magnet supported for movement toward and away from the first and second rotor magnets, the first reciprocating magnet being axially disposed in a first space within a boundary defined by longitudinally extending the outermost circumferential perimeter of the first pair of rotor magnets; and
an actuator for moving the first reciprocating magnet cyclically toward and away from the first pair of rotor magnets without passing through a center of rotation of the first pair of rotor magnets so as to simultaneously create repulsion and attraction forces with the first pair of rotor magnets to cyclically rotate the first pair of rotor magnets relative to the first reciprocating magnet in one rotational direction.

Abstract
A motor includes a rotor supported for rotation about an axis, at least one pair of rotor magnets spaced angularly about the axis and supported on the rotor, at least one reciprocating magnet, and an actuator for moving the reciprocating magnet cyclically toward and away from the pair of rotor magnets, and consequently rotating the rotor magnets relative to the reciprocating magnet.

16. A motor comprising:
-
a rotor supported for rotation about an axis;
a first rotor magnet supported for rotation about the axis along a first circumferential path having an outermost perimeter and a center at the axis, the first rotor magnet having a first permanent reference pole facing laterally toward the axis and a first permanent opposite pole facing in an opposite lateral direction toward the first reference pole;
a pair of reciprocating magnets supported for movement toward and away from the rotor magnet, including a first reciprocating magnet and a second reciprocating magnet spaced axially from the first rotor magnet, each reciprocating magnet being at least partially disposed within a first axial space having a boundary defined by longitudinally extending the outermost perimeter of the first circumferential path of the first rotor magnet, wherein the rotor magnet is located axially between the first and second reciprocating magnets; and
an actuator for moving the pair of reciprocating magnets cyclically toward and away from the rotor magnet without passing through the center of the first circumferential path so as to simultaneously create repulsion and attraction forces with the first pair of rotor magnets to cyclically rotate the rotor magnet relative to the pair of reciprocating magnets in one rotational direction. - View Dependent Claims (17, 18)
