FAQs on DC Machines - 1 Video Lecture - GATE Notes & Videos for Electrical Engineering - Electrical Engineering (EE)
| 1. What is a DC machine? |  |
Ans. A DC machine, also known as a direct current machine, is an electrical device that converts mechanical energy into direct current (DC) electrical energy or vice versa. It consists of two main parts: the stator (field winding) and the rotor (armature winding).
| 2. How does a DC machine work? | |
Ans. A DC machine works on the principle of electromagnetic induction. When electrical current is passed through the field winding in the stator, it creates a magnetic field. This magnetic field interacts with the armature winding in the rotor, inducing a voltage. When mechanical energy is applied to the rotor, it rotates within the magnetic field, generating electrical energy.
| 3. What are the applications of DC machines? | |
Ans. DC machines have various applications in industries and everyday life. They are commonly used in electric vehicles, cranes, elevators, and power plants. They are also used in battery charging systems, electric traction systems, and in various industrial processes that require precise control of speed and torque.
| 4. What are the advantages of DC machines? | |
Ans. DC machines offer several advantages. They provide a constant torque at low speeds, making them suitable for applications that require precise control. They are also relatively simple to design and operate, and can be easily controlled using electronic devices. Additionally, DC machines have high starting torque and can operate in both directions of rotation.
| 5. What are the main differences between DC machines and AC machines? | |
Ans. The main difference between DC machines and AC machines is the type of current they use. DC machines use direct current, while AC machines use alternating current. DC machines are generally more suitable for applications that require precise control of speed and torque, while AC machines are more commonly used for high power applications and long-distance power transmission.
