10 hp motor ,7.5 kw ,960 rpm, full load current 15.5, delta
connection so how much take current no load trial time. any
formula please give.....
second question :- what is different between brekar
control wiring and motor starter control wiring
Answer Posted / rajashekar
There is no separate formula for calculating no load
current, It depends upon it internal losses like Wearing &
Tearing, Bearing condition and IR losses etc.
Secondly, We can see that, In Breaker circuit only NO is
used for Closing, Opening and Triping Purpose, where as
with out NC circuit it wouldnt be complete. To trip the
motor we should break the NC element.
In India normally 110 Vdc for breaker and 230 Vac supply
for Starter control wiring.
