Abstract

A method for varying motor output using magnets of different fluxes includes manufacturing standardized parts, ascertaining desired motor output, selecting from a group of interchangeable magnets to provide the desired output, and assembling a motor with the selected magnets and standardized parts such that the desired output is provided. Additionally, a motor kit including a rotor configured to accommodate magnets of varying residual induction values and lengths, a stator configured to operate with the rotor, and a plurality of interchangeable magnets with different residual induction values and lengths.

Claims

1. A method for fabricating a motor, said method comprising the steps of:

fabricating standardized motor parts including at least one of a rotor core and a stator core;

ascertaining desired motor output;

selecting at least one magnet from a group of interchangeable magnets in accordance with desired motor output; and

assembling a motor with the selected magnet and standardized parts such that the desired output is substantially provided.

2. A method in accordance with claim 1 wherein said step of selecting further comprises the step of selecting one of a ferrite bonded magnet, a Neodymium bonded magnet and a Samarium Cobalt bonded magnet.

3. A method in accordance with claim 1 wherein said step of selecting further comprises the step of selecting from a group of interchangeable magnets with different residual induction levels and substantially similar thicknesses and lengths.

4. A method in accordance with claim 1 wherein said step of selecting further comprises the step of selecting from a group of interchangeable magnets with different residual induction levels and varying lengths.

5. A method in accordance with claim 1 wherein said step of selecting further comprises the step of selecting from a group of interchangeable ring magnets.

6. A method in accordance with claim 5 wherein said step of selecting further comprises the step of selecting from a group of interchangeable ring magnets comprising at least one crush rib.

7. A method in accordance with claim 1 wherein said step of selecting further comprises the step of selecting from a group of interchangeable magnets having substantially similar residual induction levels and different lengths.

8. A method in accordance with claim 1 further comprising:

ascertaining a second desired motor output different from the first desired motor output;

selecting at least one second magnet from the group of interchangeable magnets in accordance with the second desired motor output, the second magnet having at least one of a different length than the first magnet and a different residual value then the first magnet; and

assembling a second motor with the second selected magnet and standardized parts such that the second desired output is substantially provided.

9. A method in accordance with claim 8 wherein said selecting at least one magnet further comprises selecting one of a ferrite bonded magnet, a Neodymium bonded magnet and a Samarium Cobalt bonded magnet, and said selecting at least one second magnet further comprises selecting one of a ferrite bonded magnet, a Neodymium bonded magnet and a Samarium Cobalt bonded magnet.

10. A method in accordance with claim 8 wherein said selecting at least one magnet further comprises selecting at least one magnet from a group of interchangeable magnets with different residual induction levels and substantially similar thicknesses and lengths, and said selecting at least one second magnet further comprises selecting at least one second magnet from the group of interchangeable magnets with different residual induction levels and substantially similar thicknesses and lengths.

11. A method in accordance with claim 8 wherein said selecting at least one magnet further comprises selecting at least one magnet from a group of interchangeable magnets with different residual induction levels and varying lengths, and said selecting at least one second magnet further comprises selecting at least one second magnet from the group of interchangeable magnets with different residual induction levels and varying lengths.

12. A method in accordance with claim 8 wherein said selecting at least one magnet further comprises selecting at least one magnet from a group of interchangeable ring magnets said selecting at least one second magnet further comprises selecting at least one second magnet from the group of interchangeable ring magnets.

13. A method in accordance with claim 12 wherein said selecting at least one magnet from a group of interchangeable ring magnets further comprises selecting from a group of interchangeable ring magnets comprising at least one crush rib, and said selecting at least one second magnet from a group of interchangeable ring magnets further comprises selecting from the group of interchangeable ring magnets comprising at least one crush rib.

14. A method in accordance with claim 8 wherein said selecting at least one magnet further comprises selecting at least one magnet from a group of interchangeable magnets having substantially similar residual induction levels and different lengths, and said selecting at least one second magnet further comprises selecting at least one second magnet from the group of interchangeable magnets having substantially similar residual induction levels and different lengths.
