Why is the number of turns in the motor winding less, the cross-sectional area less than before, and the no-load current larger?

When the number of turns in the motor winding decreases, the winding inductance and inductance decrease, and the current increases when the voltage and frequency are unchanged. If the cross-sectional area of the conductor is smaller than the original, the current density will increase, the heating value of the winding will increase, and the motor will smoke due to overheating.

"Less turns, less current, because fewer magnetic induction lines are cut", which is the "patent" of the generator. When the number of turns of the generator winding is small, the electromotive force generated is small, and the current is naturally small under the condition of a certain load reactance. Generator and motor are not the same thing.
