In this course, you will learn how to use a DC motor, an electrical machine that converts electrical energy into mechanical energy. The basic working principle of a DC motor and the difference between DC generator and a DC motor will be explained in this course. In terms of structure, the DC motor and the DC generator are identical. If you want to know how to identify the terminals of a DC compound engine? You will learn through studying this course. Over time, the manufacturer's information on the terminals can fade. Therefore, we will cover how to perform continuity tests and the basics of identifying the six terminals on a DC compound motor.

Do you know there are different types of DC motors? This course explains three different types of DC motors and their characteristics. DC Shunt motors are mainly used to drive constant speed shafts, lathes, centrifugal pumps, machine tools, blowers and fans, piston pumps, etc. In addition, learn how DC series motors are used to drive electric locomotives, mass transit systems, trolleys, automobiles, cranes and hoists, conveyors, etc. Both series and compound DC motors have high starting torque compared to DC motors. We will also study how the two-point starter for series motors DC and the three-point starter for shunt motors DC plays an important role in DC motors. The resistance start method is the basic principle of both the two-point starter for DC series motors and the three-point starter for DC shunt motors. Want to know how to calculate the voltage equation, the speed-torque equation, and the feedback EMF in a DC motor? These calculations are also explained in this course with graphs and diagrams. In order to use the motor for various purposes, the speed of the motor needs to be controlled. Therefore, the methods of speed control are also explained in detail.

Want to know how to reverse the direction of rotation of a DC shunt motor? This course explains how to control the speed of a DC shunt motor using the flux control method and a variable resistor in series with the motor. The speed of a DC shunt motor can be controlled using the various control methods explained in detail in this course. By the end of this course, you will know more about DC motors and will have taken a big step towards understanding one of the most important electrical machines that power the industrial world. So why wait, start your learning journey today.
