3 phase motor plate says 200v?

You got the calcs wrong. TheArsonSmith is right. 200 volts x 23 amps x 1.73 = 7958 VA = 7.96 KVA no matter how you cut it.
It is a 7.5HP motor as indicated. 7.5HP = 5.59 KW. All that means is the motor power factor x it's efficiency = 70%. Not great, but not too bad for a motor of that size and that age

I got the formula correct (V*A*1.73 = VA) but for some reason, I got 4.6 kVA instead of the correct 7.96 kVA. I agree, .7 pf seems correct for a motor this size /vintage.
