why do we generate sinusoidal ac?can we generate some other
waveforms by alternators?
Answer Posted / fonzy umali
ALTERNATOR CAN ONLY GENERATE SINE WAVE THAT IS..0 TO 180
THEN 180 TO 360 DEGREES. DERIVE FROM THE ROOT WORD
ALTERNATOR MEANS IT VARIES FROM POSITIVE TO NEGATIVE WAVE
OR VICE VERSA..IT MIGHT PRODUCE RIPPLE DURING WHICH STATICS
OR HARMONICS BUT IT ALWAYS HAVE POSITIVE AND NEGATIVE WAVE.

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
