how to calculate the speed of a induction motor without
using tacho meter?

Answer Posted / thomas dsouza

These questions are asked for interview purpose and one
likes to test the appplication of the academic knowledge of
the candidate at times in practical situations to know
about the particular equipment. This will not be accurate
for practical conditions. However, as you mentioned, the
speed mentioned was synchronous speed only and if one knows
the % slip it can be deducted to get the actual speed.

But for any purposeful recording/analysis of the actual
speed one may have to use a measuring instrument only to
get the exact values.

If there is a better answer anybody pls advice.
