hi i wonder will the speed of a 50hz AC motor reduce if i
supply it with 25hz?
Answer Posted / vikas
As we know frequency is inversely proportional to time.if you run your AC motor with 50 hz frequency let consider
F=k/T
T=k/50
T=0.02k sec
and if frequency is 25hz
T=k/25
T=.04k sec
that means at 25hz it will take more time to complete one cycle.
thats why motor reduces its speed at 25HZ
