Abstract

Methods and systems are provided for a winch including a motor and a contactor assembly coupled around the motor. In one example, the contactor assembly is coupled around and in face-sharing contact with a portion of an outer surface of the motor. Additionally, the contactor assembly may include two or more coils spaced apart from one another within the contactor assembly.

Claims (14)

1. A motor assembly for a winch, comprising:

a motor;

a contactor assembly coupled around and in face-sharing contact with a portion of an outer surface of the motor, the contactor assembly including two or more coils spaced apart from one another within the contactor assembly;

a drum support coupled to an inner end of the motor and an inner end of the contactor assembly and wherein the motor and contactor assembly are contained within bounds defined by outer walls of the drum support; and

a motor end cap coupled to an outer end wall of the contactor assembly, the outer end wall arranged opposite an inner end wall of the contactor assembly, and contained within the bounds defined by the outer walls of the drum support.

2. The motor assembly of claim 1 , wherein components of the contactor assembly, including the two or more coils, are housed within an outer casing of the contactor assembly and wherein the outer casing includes a plurality of inner surfaces in face-sharing contact with a cylindrical outer surface of the motor.

3. The motor assembly of claim 2 , wherein the plurality of inner surfaces of the outer casing includes first and second planar surfaces that support a portion of the cylindrical outer surface of the motor, the first and second planar surfaces being angled relative to each other.

4. The motor assembly of claim 3 , wherein the portion of the cylindrical outer surface of the motor is a bottom portion relative to a vertical direction and surface on which a winch to which the motor assembly is coupled sits and wherein the contactor assembly is positioned vertically below the motor.

5. The motor assembly of claim 2 , wherein the contactor assembly includes electrical connections extending in an outward direction from an outer wall of the outer casing, the electrical connections spaced away and electrically isolated from one another.

6. The motor assembly of claim 5 , wherein the electrical connections include electrical motor connections adapted to connect to the motor, and further comprising a battery connection adapted to connect to an external power source, the battery connection extending outward from the outer casing.

7. The motor assembly of claim 6 , wherein the electrical motor connections are coupled to electrical contactor connections extending outward from the motor via wires extending between the electrical motor connections and the electrical contactor connections.

8. The motor assembly of claim 7 , further comprising a motor end cap enclosing each of the electrical motor connections, electrical contactor connections, and wires and wherein the motor end cap is coupled to the outer casing.

9. The motor assembly of claim 1 , wherein a spindle of the motor is supported within an opening of the drum support by an annular bearing.

10. The motor assembly of claim 1 , wherein an outer end of the motor is enclosed entirely by the motor end cap.
