Difference Between DC Series Motor and Shunt Motor
DC Series Motor and DC Shunt Motor form an integral part of the modern-day electronics industry. We know that there are two types of motors that can be used to convert electrical energy into mechanical energy. While one uses AC for it, the other uses DC for it.
In this article, we will study the motor that uses DC to convert electrical energy into mechanical energy. Even when dealing with DC motors, we can divide them into certain types like Series DC Motor, Shunt/Parallel DC Motor, Compound DC Motors, and Permanent Magnet DC Motor.
In this article, we will focus on Series DC Motor and Shunt DC Motor. We will see the construction and working of each of these types of DC motors and we will try to analyze the differences between the two. After comparing their work, we will study the Advantages and Disadvantages of the two types of motors.
Later we will study which applications require which kind of motor. The article concludes with some frequently asked questions that readers can refer to.
