no we cant start any motor without excitation... because the
word excitation implies the field creation, which is must to
produce a torque in motor.. if we take any motor directly or
indirectly exitation is produced first and then only motor
starts running, even in i/m also first excitation(rotating
flux) is created then only motor starts rotating
