SUMMARY
An electric motor operates through the interaction of two magnetic fields: one generated by a permanent magnet and the other by an electromagnet. The armature spins due to the attraction and repulsion of these magnetic fields, with AC motors relying on magnetic attraction and DC motors utilizing a repelling principle. Torque generated by the armature's rotation is transmitted to various components through mechanical systems such as gears, pulleys, and belts. Understanding the relationship between current and torque is crucial, as increased current results in higher torque output.
