540. As shown in the illustration, how are the rotor windings (terminating as marked motor leads M1, M2, and M3) of the motor configured
The rotor windings are configured in a wye connection because their opposite ends converge at a single common point, which is the defining characteristic of a wye (star) configuration. This differs from delta connections, which form a closed loop, and eliminates open delta and series-parallel arrangements that would require different winding groupings or fewer phases.
