Active DC Motors Kaise Kaam Karti Hain? Kya Hain Inki Specialities

DC motor koi bhi rotating electrical machine ko kaha ja sakta hai, jo ki direct current electrical energy ko mechanical energy me convert kar sake. Sabse common type ki DC motors magnetic fields ke karan ban ne wali force pe depend karti hai. Zyadatar sabhi type ki DC motors me koi na koi internal mechanism hota hai , bhale hi wo electromechanical ho ya electronic. Us mechanism ke through motor ke parts me current ka direction periodically change kia jata hai.

DC motors sabse pehle use ki jane wali motor hai. Ye islie, kyun ki ye motors direct current se chalti hai. DC motor ki speed kai tarreko se and kafi range me control ki ja sakti hai, ya to variable supply voltage use karke, ya to field winding me current ki strength change karke.

Active DC Motors Construction

DC motor main do parts se bana hota hai. Rotate hone wale part ko Rotor kehte he, and jo stationary wala part hai, use stator kehte hai. Rotor stator ke respect me ghoomta hai.

Rotor me windings hoti hai, jo ki commutator se electrically connected hoti hai. Brushes, commutator contacts or rotor windings ka shape wesa hota hai, jis se jb power apply ki jae, tb energized winding or stator magnets ki polarity sahi aligned na ho. Or rotor tab tak ghoomega, jab tak wo stator field magnets se lagbhag straightened rahe.

Jb rotor alignment pe phuch jata hai, brushes agle commutator contacts pe move kar jate hai and agli winding ko energise karte hai. Rotation ke karan rotor winding me current ka direction change ho jata hai. Jis se rotor magnetic field bhi change hoti hai, and rotate hoti rehti hai.

Active DC Motors Working

DC motor ki working simple electromagnetism pe depend karti hai. Wo conductor, jisme se current flow ho ra ho, wo magnetic field generate karta hai. Jab wahi coil bahr ki magnetic field me rakhi jati hai, to uspe ek force lagta hai, jo ki conductor ke current or bahr ki magnetic field ki strength ke proportional hoti hai.

DC motor ka basic principle yahi hai ki jab current carry krne wale conductor ko bahr ki magnetic field me rakha jata hai, to woe k force experience karta hai. Us force ke karan wo coil rotate hone lagti hai.

Uses Of Active DC Motors

Small DC motors kai tools, toys and appliances me use ki jati hai. Large DC motors electric vehicles, lifts and steel rolling mills ko chalane ke lie use ki jati hai. Power Electronics ka ijad DC motors ko hata ke AC motors lane ke lie hi hua, jo ki kai jagah pe use ki ja sakti hai.

Advantages of Active DC Motors

  • DC motors kafi accha speed control karte hai, acceleration and deceleration ke lie.
  • Design samjhne ke lie easy hai.
  • Design simple or cheap hai.
