![]() Major parts are rotor (armature) and stator (field). ![]() ![]() Principle of magnetic induction in DC machineĭC motors are everywhere! In a house, almost every mechanical movement that you see around you is caused by an DC (direct current) motor.Īn dc motor is a machine that converts electrical energy into mechanical energy by supplying a dc power (voltage and current). In this example, the ends of the wire loop have been connected to two slip rings mounted on the shaft, while brushes are used to carry the current from the loop to the outside of the circuit. While dc motors are widely used in many applications.Ī dc generator is a machine that converts mechanical energy into electrical energy (dc voltage and current) by using the principle of magnetic induction. DC generators are not as common as they used to be, because direct current, when required, is mainly produced by electronic rectifiers. Discuss the operating differences between different types of generators Understand the principle of DC generator as it represents a logical behavior of dc motors.ĭirect-current (DC) machines are divided into dc generators and dc motors. State the principle by which machines convert mechanical energy to electrical energy. Upon completion of the chapter the student should be able to: – – – ![]() ![]() Overview of Direct Current Machines Construction Principle of Operation Types of DC Motor Power Flow Diagram Speed Control ![]()
