AC synchronous motors operate at the same frequency as the electric power supply, while AC asynchronous motors do not maintain a constant speed, as their speed varies with load changes. In contrast, DC motors feature stationary outer magnets and a rotating inner rotor made of electromagnets, powered by commutators. The polarity of the rotor alternates as it spins, creating a cycle of attraction and repulsion with the outer magnets. AC motors utilize a combination of changing magnetic fields in both the stator and rotor, which consist of electromagnets.
