good morning everyone,,,,,,,,
aaj ke iss lecture me ham aapko btaane waale hain,
ye goverment polytechnic college ka second year ka electrical engineering ka experiment hai.
ham aaj aapko DC MOTOR AUR GENERATOR KE CHARACTERISTIC  KE BAARE ME BTAAENGE.
HAM AAJ AAPKO DC MOTOR AUR GENERATOR KI SHUNT,SERIES,COMBINED KE BAARE MAI BATAAYENGE.
DC MOTOR KYAA HAI?
DC MOTOR AIK AISE MOTOR HAI JO DC SUPPLY SE  OPERATE  HOTI HAI.
HAMAARA AAJ KA TOPIC DC GENERATOR HAI,,,,,,,
HAMAARA AAJN KA SC GENERATOR KA TOPIC HAI SHUNT GENERATOR.......
YE HAMAARA DC MOTOR-GENERATOR KA DIAGRAM HAI,,,,,,
FIRST OF ALL DC SUPPLY DI HAI ,,,,
 
USKE BAAD STARTER KO CONNECT KYAA HAI
HAMNE SUPPLY MOTOR KO DI HAI
HAMARI MOTOR GENERATOR SE  MECHNICALY COMBINE HAI
MOTOR SE HAMAARA GENERATOR START HO JAATA HAI,,,,
JB HAMAARA GENERATOR ROUTE KARNE LAGTAA HAI TO ABB USPR HAMKO KAISE OUTPUT MILEGAA YE AAGE DEKHIYE,,,,
HAMAARE GERERATOR KE OUTPUT ME SIX TERMINAL HAIN,,,,,
YE HAMAARA RECTIFIER HAI,,,,
YE HAMAARA DC MOTOR STARTER HAI,,,,,
YE BULB HAMNE GERERATOR KE OUTPUT KE LIYE AS A LOAD USE KIYE HAIN,,,,,
ABB YAHAN YE DEKHNE WAALI BAAT YE  HAI KI WITHOUT LOAD  (JB HM GENERATOR KE TERMINAL KO OPEN RAKHTE HAIN ) HAMKO VOLTAGE ZYAADA MILTAA HAI AUR LOAD LAGANE PR TERMINAL VOLTAGE KM HO JAATA HAI
