The winch motor turns the electrical energy into mechanical energy. The motor shaft powers
the gears, which in turn pulls the load. For the winches with a brake, it will hold the load if
user must stop.
On power-in operation, the drive shaft rotates and drives the planetary gears, starting with the
gear carrier stage farthest from the winch drum (the first stage carrier.) The first stage carrier,
in turn, drives the second stage carrier, which then drives the third stage carrier. The third
stage directly drives the drum. Since the wire rope is connected to the drum, the rope winds
around the drum, causing the load to be drawn in.
On power-out operation, the motor is reversed and the winch drum is rotated in the opposite
direction. All winch components operate in the same manner as during power-in.
In stopped position, the switch activates the “dynamic braking” effect of the motor , resisting
additional turning of the wire rope drum.
