Notes on dc machine
WebThe losses that occur in a DC Machine is divided into five basic categories. The various losses are Electrical or Copper losses (I 2 R losses), Core losses or Iron losses, Brush … WebThe armature reaction in an alternator is, a 3-phase voltage can be induced by the stator winding, because of the revolving magnetic field from the rotor. Here the circuit of the stator is called an armature circuit. When the stator doesn’t have any load across it, then the total voltage can be induced at the winding of the stator which comes ...

WebMar 22, 2024 · • An dc motor is a machine that converts electrical energy into mechanical energy by supplying a dc power (voltage and current). • An advantage of DC motors is that it is easy to control their speed in a wide diapason. Construction of DC machine Cutaway view of a dc motor Stator with poles visible. WebAug 22, 2024 · It is an important part of any machine that generates necessary torque for the movement of the rotor. The armature winding can be placed either on a stator or rotor. If the machine is to be operated with AC (alternating current), then the armature is placed on a stator. It is to be operated as DC (Direct current), then it is arranged on a rotor.
WebA DC motor is used to convert the direct current (DC) electrical power into mechanical power based on the forces produced by magnetic filed (s). The output of the motor is mechanical power in terms of rotation (speed) of the shaft. According to the applications, we need to change the speed of the motor.
