 
HI FRIENDS, WELCOME TO M4 TECH.
TODAY WE'RE GONNA MAKE,
A HOMEMADE ELECTRICITY GENERATOR.
THIS IS IDEAL FOR STUDENTS.
YOU'D HAVE LEARNT IT THEORETICALLY,
NOW YOU CAN UNDERSTAND IT PRACTICALLY.
SIMILARLY WE CAN ALSO MAKE THIS ONE.
FOR THAT WE'RE USING THIS DC MOTOR.
LET'S SEE THE REMAINING WORK IN WORKSHOP.
WE'RE IN WORKSHOP NOW.
WE NEED COUPLE OF THINGS TO MAKE GENERATOR.
ONE IS DC MOTOR.
 
250W AND 24V DC MOTOR.
WE USED THIS FOR ELECTRIC CYCLE.
THEN WE NEED AN ENGINE.
WE'VE TAKEN A PETROL ENGINE.
THIS IS GRASS CUTTING MACHINE'S ENGINE.
THIS IS JUST TO SHOW THE WORKING.
MILEAGE WILL BE VERY LESS.
FOR GENERATORS WE NORMALLY USE
DIESEL OR KEROSENE.
WITH THIS WE'LL START OUR WORK.
OUR HERO FOR OUR WORK IS THIS
DC MOTOR.
BECAUSE WHEN WE APPLY ELECTRICITY ON THESE WIRES,
THIS MOTOR WILL CONVERT IT INTO MECHANICAL ENERGY.
BUT WE'RE GOING TO DO ANOTHER THING WITH THIS.
IN THIS SHAFT WE'RE GONNA APPLY MECHANICAL ENERGY
AND GENERATE ELECTRICITY FROM IT.
SO WE'RE CONVERTING MECH TO ELECTRIC ENERGY.
TO ALIGN OUR MOTOR AND
ENGINE, WE'VE MADE A STAND.
 
IN THIS WE'RE GONNA KEEP OUR PETROL ENGINE.
THIS ENGINE WILL PROVIDE
THE MECHANICAL ENERGY FOR US.
IN THIS STAND,
LET'S PLACE IT.
 
WE'LL TIGHTEN IT WITH NUT AND BOLT.
 
WE'VE SET THE ENGINE.
WE NEED TO SET THE DC MOTOR
WITH THE SIMILAR WAY WHERE THIS ENGINE'S SHAFT IS.
WE'VE THIS WOODEN BLOCK TO ALIGN IT.
 
IF WE KEEP LIKE THIS, IT WON'T JOIN.
SO WE'LL TAKE THIS HOSE TUBE AND
PLACE COUPLE OF CLAMPS.
AFTER THAT
WE CAN INSERT IT IN.
 
PUSH IT WELL.
 
NOW WE'LL TIGHTEN THE CLAMP.
 
 
 
NOW WE'LL FIX THE MOTOR
IN THE WOODEN BLOCK.
 
MAKING PROCEDURE OF GENERATOR IS OVER.
WE'LL ADD FUEL TO IT.
ADD IT IN.
LITTLE WOULD BE ENOUGH.
 
CLOSE IT.
WORK IS OVER.
BEFORE SWITCHING IT ON,
WE CAN CONNECT THE 12V BULB.
AFTER THIS WE CAN CHECK HOW MUCH VOLTS WE'LL GET.
WE CAN CONNECT IT PROPERLY.
CONNECTED IT.
LET IT BE THERE.
NOW WE'RE GONNA START THE ENGINE.
SWITCHED IT ON.
WE WOULD'VE SEEN THIS EARLIER.
START THE ENGINE.
I THINK WE'VE GOT MORE THAN 12V POWER.
BULB HAS SHORTED.
VOLTAGE IS NOT STABLE.
SINCE WE COULDN'T CONTROL IT,
THE BULB IS GONE.
LET'S SEE HOW MUCH VOLTAGE IS GENERATED.
WE CAN CONNECT THIS MULTIMETER
TO CHECK IT.
 
WE'LL PUT IT TO VOLTAGE CHECK.
I THINK WE'LL GET NEAR 200V.
IF WE START, YOU MIGHT NOT HEAR
WHAT I SAY.
DUE TO VIBRATION IT SHOWS 1V.
WE CAN SEE IT INCREASING.
140V
190V
IT WENT MORE THAN 200,
THAT'S WHY IT SHOWED 1.
WE'VE SET IT TO 1000.
LET'S TEST IT.
 
 
 
IT WENT BEYOND 2000
WE CAN SEE IT CAN
REACH TILL 2000 WHEN WE GIVE THROTTLE.
 
WE CAN ONLY CHECK TILL
2000V IN THIS MULTIMETER.
IT CROSSED 2000V.
IN OUR HOUSE WE GET 230V AC.
BUT WE GOT 2000V DC.
IT IS BEYOND OUR EXPECTATION.
 
2000V.
IT IS MORE THAN 2000.
IN THIS GENERATOR WE'RE
GETTING 2000V.
SO NO WONDER WHY OUR BULB GOT SHORTED.
EARLIER WE GAVE ONLY
LITTLE THROTTLE AND
THAT'S WHY BULB WAS GLOWING.
WE CAN PRODUCE MORE THAN 4000V
AS WE GET HIGH RPM IN THIS.
ANOTHER SPECIALITY IS
VOLTAGE IS GENERATED ACCORDING TO RPM.
 
 
THIS IS THE SIMPLEST WAY
TO EXPLAIN A GENERATOR.
DYNAMO SECTION IS THE MAIN
ONE AND IT IS THIS MOTOR.
JUST LIKE CYCLE'S DYNAMO.
SO TO MAKE THIS MOTOR WORK,
WE NEED TO APPLY MECHANICAL ENERGY INTO IT.
THAT IS WHY WE'RE USING THIS
PETROL ENGINE.
 
 
THE MECHANICAL ENERGY RECEIVED IS
CONVERTED INTO ELECTRICAL ENERGY.
THIS IS THE SETUP WE SEE
USED WHEN THERE IS POWER FAILURE.
IN POWER PLANT ALSO, THIS TECHNIQUE IS USED.
HOPE YOU UNDERSTOOD
THE WORKING OF GENERATOR.
HOPE IT'LL BE HELPFUL FOR STUDENTS.
