Winch with Brake

Open Model

This example shows a winch driven by a DC motor and controlled with a double-shoe brake. The motor is connected to a 24 volt supply, and the shaft speed is stepped down with a 10:1 gear reduction. The pulled load is modeled as a mass with sliding friction. At a simulation time of six seconds, force is applied to an internal double-shoe brake, stopping the winch.

The plot below shows the position of a mass dragged across a floor by a winch. When the brake is applied, the mass stops moving. This stalls the motor, increasing the amount of power it draws from its voltage source.
