Abstract
The present invention relates to motors and, more specifically to rotary motors which can supply output motive power about an output axis in response to input rotary power about a different axis. A motor (1) comprises a wheel (2) mounted on a shaft (3) for rotation about a first axis (4). The shaft (3) is additionally mounted for rotation about both an inclination axis (16) and the output axis (11) of the motor (1).
Claims48
A method of generating rotation about an output axis (11), the method comprising:
- A) mounting a body (2) for rotation about first (4), second (11) and third (16) axes, the first axis (4) being oriented with respect to the second axis (11) at an inclination angle (θ), the second axis (11) constituting an output axis (11) of a motor (1), wherein rotating the body (2) about the third axis (16) gives rise to a change in the inclination angle (θ);
- B) rotation the body (2) about the first axis (4) at a rotational speed in excess of a predetermined value;
- C) applying a torque to the body (2) about the third axis (16) in a direction to increase inclination angle (θ) when the first axis (4) is at a selected inclination angle (θ) with respect to the second axis (11) which is greater than 0 degrees and less than 90 degrees, thereby to generate a counter-torque about the third axis in a direction to decrease inclination angle (θ);
- D) limiting rotation of the body (2) about the third axis (16) in a direction to decrease inclination angle (θ) which would otherwise occur as a result of the counter-torque, such that the inclination angle (θ) of the first axis (4) with respect to the second axis (11) remains greater than 0 degrees and less than 90 degrees;
- thereby to initiate, or to increase the speed of, rotation of the body (2) about the second axis (11) so as to generate motive power.

A motor for generating rotation about an output axis (11), the motor (1) comprising:
- a) a body (2) mounted for rotation about first (4), second (11) and third (16) axes, the first axis (4) being oriented with respect to the second axis (11) at an inclination angle (θ), the second axis (11) constituting the output axis (11) of the motor (1), wherein rotation of the body (2) about the third axis (16) gives rise to a change in the inclination angle (θ);
- b) the motor (1) being so structured as to enable a source of motive power (12) to be connected to the body (2) to cause it to rotate about the first axis (4) at a rotational speed in excess of a predetermined value;
- c) means (15) for applying a torque to the body (2) about the third axis (16) in a direction to increase inclination angle (θ) when the first axis (4) is at a selected inclination angle (θ) with respect to the second axis (11) which is greater than 0 degrees and less than 90 degrees, thereby to generate a counter-torque about the third axis in a direction to decrease inclination angle (θ);
- d) means (15) for limiting rotation of the body (2) about the third axis (16) in a direction to decrease inclination angle (θ) which would otherwise occur as a result of the counter-torque, such that the inclination angle (θ) of the first axis (4) with respect to the second axis (11) remains greater than 0 degrees and less than 90 degrees;
- thereby to initiate, or to increase the speed of, rotation of the body (2) about the second axis (11) so as to generate motive power.
