how we calculate the 30 KW 3phase electric motor current on
noload
Answer Posted / janardan
For 2 pole motor; No load current will be the 1/3 of the Full load current.
i.e if motor takes 181.00 full load current then the no load current will
181 X 1/3 = 60.33 amp.
* for 4 pole: 1/3 to > 3/8
for 6 pole: 1/3 to <1/2
for 8 pole: 1/3 to 5/8
