3. The winch according to claim 2 , wherein the armature terminal and the field terminals are linearly aligned with one another along a top side of the first drum support.
4. The winch according to claim 1 , wherein the screw boss is positioned along a bottom side of the first drum support.
5. The winch according to claim 1 , further comprising a gear reduction unit, drivingly attached to the motor.
6. The winch according to claim 1 , further comprising a rotatable drum drivingly attached to the motor, wherein the rotatable drum is supported by the first drum support and a second drum support.
7. The winch according to claim 1 , wherein the motor includes a brush holder assembly attached to the first drum support via a brush plate, the brush plate supporting a plurality of brushes contacting an armature of the motor.
8. The winch according to claim 7 , wherein the brush plate of the motor is mounted to the first drum support by a plurality of grounding screws.
9. A winch, comprising:
a motor having a motor housing that includes a motor case and a first drum support coupled to the motor housing, such that the motor case couples with the first drum support to enclose the motor within the motor case and first drum support, the first drum support including a grounding screw boss positioned along a bottom side of the first drum support; wherein the grounding screw boss receives a fastener in electrical communication with ground cable of a battery;
a gear reduction unit, drivingly attached to the motor; and
a rotatable drum drivingly attached to the motor, wherein the rotatable drum is supported by the first drum support and a second drum support.
10.

11. The winch according to claim 10 , wherein the armature terminal and the field terminals are linearly aligned with one another along a top side of the first drum support.
12. The winch according to claim 9 , wherein the motor includes a brush holder assembly attached to the first drum support via a brush plate, the brush plate supporting a plurality of brushes contacting an armature of the motor.
13. The winch according to claim 12 , wherein the brush plate of the motor is mounted to the first drum support by a plurality of grounding screws.
14. A winch, comprising:
a motor having a motor housing that includes a motor case and a first drum support coupled to the motor housing, such that the motor case couples with the first drum support to enclose the motor within the motor case and first drum support, the first drum support including a grounding screw boss positioned along a bottom side of the first drum support; wherein the grounding screw boss receives a fastener in electrical communication with ground cable of a battery;
a gear reduction unit drivingly attached to the motor and having a gear housing including a gear case and a second drum support attached to the gear case to enclose an end of the gear case; and
a tie structure including two planar side rails connecting the first and second drum supports and two planar cross rails coupling the two side rails to one another, the two side rails angled relative to the two cross rails.
15. The winch according to claim 14 , wherein the motor further includes an armature terminal electrically coupling an armature of the motor to a control unit of the winch and field terminals electrically coupling a field coil assembly of the motor to the control unit, the armature terminal and field terminals attached to the first drum support.
16. The winch according to claim 15 , wherein the armature terminal and the field terminals are linearly aligned with one another along a top side of the first drum support.
17. The winch according to claim 14 , wherein the motor includes a brush holder assembly attached to the first drum support via a brush plate, the brush plate supporting a plurality of brushes contacting an armature of the motor.
