DC Electric motors convert nearly half of the worldwide electric energy into mechanical energy. In many industrial applications DC motor finds a good place for variable speed and versatile operations due to its easy controllability. This paper deals with the energy conservation for a separately excited DC motor by applying speed control technique.
A DC motor is a machine that converts electrical energy of direct current into mechanical energy. In a DC motor, the input electrical energy is direct current which is converted into mechanical rotation.
DC motors are used in applications where speed control is required. They are commonly found in trolleys, electric train production systems, elevators, etc. DC motor, also known as a direct current motor, is an electric motor that converts mechanical energy from the electrical energy of direct current.
