how can you calculate the value of external resistance
inserted in a slipring industion motor? (eg. 110 kw / 990
rpm/50Hz/stator v-415/stator Amp-195/Rotor V-440/Rotor amps-
151.)

Answer Posted / rakesh patel

Formula: K=
R.V/1.73R.A
where R.V=Rotor
voltage ,
R.A=Rotor
Current ,
K=constant ,
than
1step=1.40K ,
2step=.35K ,
3step=.15K ,
4step=.08K now
put the data and
get your ans.
