Standards – Referred standards are IS:325(Performance), IS:1231(Dimensions of Foot Mounting), IS:2223(Dimensions of flange Mounting), IS:12615(Efficiency), IS:12065(Noise) and IS:12075(Vibration).
ASSISTED POWER COOLING
Three-phase 400/50 400/60, IP 55, with separate terminal box
for applications where the motor will be operated below^ a frequency of 25Hz and above 60 Hz, the appropriate assisted power cooling must be mounted as there are too many variables involved to determine the various possible thermal duties, and thus the temperatures reached by the motors
