Wonder if API 541 motor can withstand out-of phase torque during bus transfer or autoreclosing? Thanks.

RE: Motor Out of pahse torque
NEMA MG-1 20.34 recommends slow transfer / reclose (> 1.5 open-circuit time constants... gets residual voltage well below 33%... actually 22%).... for fast transfer reclose they recommend an engineering study.
Of course a discussion with oem regarding whatever you have in mind can't hurt...
