11KW Delta motor is taking about 44Amps in star and goes
upto 70Amps in delta and trips OFF. The rated current is
26Amps. Application is for the blower. The motor takes ( no
load without coupling impller ) only 2.5A and 5Amps in star
& delta starter test.Need to know why its taking high
current.
Answer Posted / rajendran
The motor takes very less current at no load than the
normal and when it is loaded it is taking the obnormal
currents even in delta operating mode....
it seems there must be a problem in the connections or in
the supply voltage of the mains or improper impeller
arrangement causing very high load.
probably there may be a problem in the connections only...
check the connections
