    Maybe they got it wrong. And maybe there is no maybe.
    The 153A on no load would ring alarm bells for me.

    you are projecting cupcake

    weg says the nla/fla is 50-65% for >200 hp dahlander (pole changing) motor
    145 to 190 A
    due to basically 8 pole low speed motor design
    seems in range

    normal 4 pole 30-40%
