INTRODUCTION. A motor is a machine which converts electrical energy into mechanical energy. A DC motor finds application in rolling mills, in traction system and overhead cranes. The principle of operation of DC motor is that when a current carrying conductor is kept in a magnetic field, a force is produced in that conductor. . Electricity - The Dangers. About 5 workers are electrocuted every week. Causes 12% of young worker workplace deaths . Takes very little electricity to cause harm . Significant risk of causing fires.
