Windage loss in a synchronous motor is primarily due to the friction of the rotor moving through the air and does not vary significantly with the load. It is more related to the speed of the rotor, which is constant in a synchronous motor. Copper losses, on the other hand, depend on the current flowing through the windings, which varies with load.
