Controller DefinitionIn control systems, a controller is a mechanism that seeks to minimize the difference between the actual value of a system (i.e. the process variable) and the desired value of the system (i.e. the setpoint). Controllers are a fundamental part of control engineering and used in all complex control systems.Before we introduce you to various controllers in detail, it is essential to know the uses of controllers in the theory of control systems. The important uses of the control

What is the Operating Principle of DC Motor?DC Motor DefinitionA DC motor is defined as a device that converts direct electrical energy into mechanical energy using magnetic fields and electrical currents.DC motors play a crucial role in modern industry. Understanding the working principle of a DC motor, which we explore in this article, begins with its fundamental single loop construction.The very basic construction of a DC motor contains a current carrying armature, connected to the supply end

What is the Torque Equation of DC Motor?Torque DefinitionTorque in a DC motor is defined as the force’s tendency to cause or change rotational motion.When a DC machine is loaded either as a motor or as a generator, the rotor conductors carry current. These conductors lie in the magnetic field of the air gap.Thus each conductor experiences a force. The conductors lie near the surface of the rotor at a common radius from its center. Hence torque is produced at the circumference of the rotor and ro
