A DC motor works by converting electric power into mechanical work. This occurs by forcing current through a coil and producing a magnetic field that spins the motor. This electric current is supplied through a commutator. The battery pack forces voltage through the coil via brushes that are connected to the DC source. These brushes are found on the end of the coil wires and make a temporary electrical connection with the voltage source. In a typical DC motor the brushes will make a connection every 180 degrees and current will then flow through the coil wires.
