This is a very simple machine
It has two main components: an electric motor and an impaler.
The electric motor is an AC unit, which means it runs on an Alternating Current. This means that the magnetic field in the motor is alternating with the current. This is needed because if the current was continous, the magnetic field would be constant, and the torque would be short lived. This is because the rotor would be drawn to the field, then stop at the field. When the current is alternating, it can change the direction of the torque.
The system does not have a safety fuse, just a motor, switch, and power chord.
