Motor de corriente CONTINUA y ALTERNA► [DIFERENCIAS] ✅

Summary

This video explores the differences between DC (Direct Current) and AC (Alternating Current) motors, commonly known as CEE and ACE motors in Spanish. DC motors are powered by a constant flow of electricity, often from batteries or DC power supplies, while AC motors operate on varying currents. The construction of DC motors includes brushes and a commutator, which can increase maintenance needs and limit speed and lifespan. Conversely, AC motors are brushless, offering robustness and longevity. Speed control in DC motors is achieved by varying the current in the rotor's winding, whereas AC motors' speed is adjusted by changing the frequency, typically with a frequency converter.
