Hello friends, i hope you people are fine and enjoying. Proceeding to my previous tutorial, in which i explained Brushless DC motor in detail. Now in this tutorial i am going to explain in detail the second type of DC motor which is Brushed DC motor. In this tutorial, we will see what is in fact a Brushed DC motor, how it works and what are the advantages and practical application of this type of motor on some other type of motors. Brushed DC motors are also known as commutated DC motors. Reason is that these motors contain commutator and carbon brushes for rotor excitation. I will explain all these terminologies in detail, later in tutorial. These are the most important type of motors designed to run directly on DC power supply. These were the very first type of motors, which were designe ...
Hello everyone, I hope you are doing well. In this tutorial, we will compare DC and AC motors from their operating principles to their speed control, maintenance and applications. Both convert electrical energy into mechanical energy through electromagnetic force, but those broad labels contain several different motor families. The first important correction is that an AC motor is not simply a DC motor with continuous slip rings. Most industrial AC motors create a rotating stator field and use either induction or synchronous interaction to produce rotor torque. We will therefore compare common brushed DC motors, brushless DC motors, induction motors and synchronous AC motors. Figure: A small DC motor introduces the comparison of DC and AC motor operation. DC and AC Motor Comparison Feature ...
