Electrical Machines. 2. Introduction. Electro mechanical device converts energy between electrical and mechanical forms.. Electromechanical energy conversion theory helps in representing electromagnetic force or torque in terms of such parameters like electric current or displacement.. 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. . Electrical Machines Getu.G:getugaa@yahoo.com.
