Question-1. Define Rotor?
Answer-1: Rotating device in an electric Motor which rotates about the Brush DC Motor generating torque among the rotor?s axis.
Question-2. Define Stator?
Answer-2: The part of the Brush DC Motor that is stationary.
Question-3. Define Torque?
Answer-3: The ability of a force to rotate a given object about an axis or fulcrum.
Question-4. How does Over current occures in motor?
Answer-4: Over current can lead to damaged equipment due to excessive heat produced within a Brush DC Motor. This occurs because a larger amount of electric current is produced through the conductor.
Question-5. How speed is maintain in Brushed Series Wound Motor?
Answer-5: The speed varies automatically with the load, increasing as the load decreases.
Question-6. How speed is maintain in Brushed Shunt Wound Motor?
Answer-6: It run at constant speed regardless of the load.
Question-7. List 3 basic applications of the Brush DC Motor?
Answer-7: The three basic applications of the Brush DC Motor are:
Household appliances
Automobiles
Radio-Controlled Toys
Question-8. List the five basic Brush DC Motor types?
Answer-8: The five basic brush DC motor are:
Brushed shunt mount Motor
Brushed series wound Motor
Brushed compound Motor
Brushed permanent magnet Motor
Brushed separately excited Motor.
Question-9. List the four components of a Brush DC Motor?
Answer-9: The four components of Brush DC Motor are Stator, Rotor/Armature, Commutator, and Brushes.
Question-10. What are Brushed Compound Motor?
Answer-10: A combination of the brushed shunt and brushed series wound Motors by combining the characteristics of both.
Question-11. What are Brushed Permanent Magnet Motor?
Answer-11: It contains permanent magnets inside, which eliminates the need for external field current. This design yields a smaller, lighter, and energy-efficient Brush Motor.
Question-12. What is Armature and where it is located in the motor?
Answer-12: The component of the Motor that produces power. It can be located on either the stator or the rotor.
Question-13. What is the basic principle in which a Brush DC Motor operates on?
Answer-13: Electromagnetism
Question-14. What is the main function of Brush in motor?
Answer-14: It act as a mechanism that conducts current in between moving parts and stationary wires.
Question-15. What is the main use of Brushed Separately Excited Motor?
Answer-15: It is used for its high torque capability at low speeds. This is achieved by separately generating a high stator field current and enough armature voltage to produce the required rotor torque current.
Question-16. What is the most critical component of a Brush DC Motor?
Answer-16: Carbon Brushes
Question-17. What is the role of Commutator in motor?
Answer-17: It is a mechanism which reverses the direction of current in certain electric Motors.
