The main function of a DC motor is to convert electrical energy into mechanical energy. This is achieved through the principle of magnetic induction, where a current-carrying conductor experiences a force when placed in a magnetic field.

Here are the steps of how a DC motor works:

1. When the DC motor is powered on, current flows through the armature (the coil of wire).
2. This current-carrying armature is then placed in an external magnetic field produced by permanent magnets or electromagnetic poles.
3. According to Fleming's Left-Hand Rule, the interaction of the magnetic field with the current causes a force to act on the armature, causing it to rotate.
4. The direction of rotation can be reversed by reversing the direction of current flow or the magnetic field, but not both.
5. The rotating armature is connected to the machine or device that needs mechanical energy, thus completing the conversion process.

So, the main function of a DC motor is not to convert mechanical energy into electrical energy or to control the flow of current in a circuit. Those are functions of a generator and a resistor, respectively.
