Mastering DC Motors: Operation, Control, Braking

This course covers the comprehensive understanding of DC motors, their operations, control mechanisms, and braking. It delves into the fundamental concepts of DC motor operations, focusing on the starting, speed control, and braking of the motor. For instance, it explains the importance of the back EMF equation and the torque equation in understanding the operation of a DC motor. The course also discusses the role of armature resistance in controlling the starting current and the use of external resistance to limit this current. It introduces the concept of a 3-point starter, an electromechanical device used to start a DC shunt motor, and explains its operation and protective features. The course concludes with a brief introduction to the speed control of DC motors.
