Answer Posted / ketan patekar
90 KW motor full load current carrying capacity is 236 ampere..
And yes when you connect load than afcourse your motor will carry ampere as per your load.
So here everything is ok.
If your motor carrying above 236 ampere current than there is some fault like your load is high or impeller or frame or design problem etc
