Reduced size and reconfigurable winch

1. A winch assembly, comprising:

a drum, adapted to hold cable thereon, wherein said drum is substantially hollow, forming a cavity inside the hollow portion of the drum; and

a motor assembly, rotating to create rotational force for the drum, said drum being rotated to cause the cable to pay on to the drum and to also pay off of the drum, wherein said motor assembly is only partly mounted inside the drum and where a first side of said motor assembly extends outside of said drum and exposed to an ambient environment, a second opposite side of said motor assembly providing rotational force, said motor assembly also including a gearing assembly connected directly to said motor assembly, and a drive shaft connected to said gearing assembly; and

a brake assembly, connected directly to said gearing assembly, inside said drum.

2. An assembly as in claim 1 , wherein said gearing assembly is a planetary gear assembly, coupled to said motor, where said planetary gear assembly is mounted inside said drum.

3. An assembly is in claim 1 , wherein said winch is a zero fleet winch, and further comprising a roller assembly, positioned to receive a cable that is wound on said drum, a shaft extending from said drum, and a timing belt coupled to said shaft, and at least one acme screw, driven by said timing belt that moves said roller assembly in sync with a rotation of said drum such that said roller assembly follows a position at which said cable winds on or off the drum.

4. An assembly as in claim 3 , further comprising a sheave assembly, coupled to receive cable that has passed over said roller assembly, wherein said sheave assembly is replaceable.

5. An assembly as in claim 4 , wherein said sheave assembly is configured for a dead haul.

6. An assembly as in claim 4 , wherein said sheave assembly is configured for a dual operating winch configuration.

7. An assembly as in claim 4 , wherein said sheave assembly includes plural different sheave wheels, each at a different angle.

8. A winch assembly, comprising:

a drum, holding cable on a surface thereof, and rotating to wind cable on and wind cable off said surface, wherein said drum is substantially hollow, forming a cavity inside the hollow portion of the drum; a mounting plate, inside said drum, said mounting plate coupled to surfaces of said drum and forming a mounting surface inside said drum;

a motor and gear assembly, having a motor that is energized to rotate to create rotational force for the drum, at least a portion of said motor and gear assembly being mounted inside the drum, and said motor and gear assembly being connected only to said mounting plate and to said drum; and

a brake assembly, connected to said mounting plate, inside said drum.

9. An assembly is in claim 8 , wherein said winch is a zero fleet winch, and further comprising a roller assembly, positioned to receive a cable that is wound on said drum, where said roller assembly is driven in sync with a rotation of said drum such that said roller assembly follows a position at which said cable winds on or off the drum.

10. An assembly is in claim 9 , wherein said drum has grooves on an outer surface thereof, each groove holding a single strand of said cable.

11. An assembly as in claim 9 , further comprising a shaft extending from said drum, and a timing belt coupled to said shaft, and at least one acme screw, driven by said timing belt that moves said roller assembly in sync with said position.

12. An assembly as in claim 9 , further comprising a sheave assembly, coupled to receive cable that has passed over said roller assembly, wherein said sheave assembly is replaceable.

13. An assembly as in claim 9 , wherein said sheave assembly includes plural different sheave wheels, each at a different angle.

14. An assembly as in claim 9 , wherein a first end of said motor is exposed to an ambient environment, a second opposite side of said motor assembly providing rotational force, and said gear assembly connected directly to said motor assembly.
