DC Motor or Direct Current Motor | Electrical4U

Jan 28, 2019· Principle of DC Motor. When a current carrying conductor is placed in a magnetic field, it experiences a torque and has a tendency to move. In other words, when a magnetic field and an electric field interact, a mechanical force is produced. The DC motor or direct current motor works on that principal. This is known as motoring action.
