PPT-CHAPTER 3 DC MOTOR 1 Electrical Machines

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 .
