Motor de corriente CONTINUA y ALTERNA► [DIFERENCIAS] ✅
Summary
TLDRThis 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.

ahora quedan muchachos esto es potencia
hp y hoy les traigo un vídeo acerca de
las diferencias entre el motor de cee y
el motor ace
dc viene del inglés de aire de carmen
que se traduce como corriente directa
hace viene del inglés alternating carne
que se traduce como corriente alterna
paréntesis al motor de ce también se le
llama motor cc motor de corriente
continua
ambos motores convierten la energía
eléctrica en energía mecánica ahora
pasemos a ver las diferencias
la principal diferencia radica en su
fuente de poder
los motores de cee son alimentados por
corriente continua por ejemplo baterías
fuentes de alimentación de cee
convertidores de corriente de ac/dc por
otro lado los motores ace son
alimentados de corriente alterna
la segunda diferencia está en su
construcción
los motores de cee son construidos con
escobillas y un conmutador lo cual
aumenta el mantenimiento limita la
velocidad y reduce el periodo de vida de
los motores de cee con escobillas
mientras que los motores ace no usan
escobillas son muy robustos y tienen un
largo periodo de vida
la tercera diferencia está en el control
de su velocidad
la velocidad de los motores de cee es
controlada mediante la variación de la
corriente del devanado de la armadura es
decir el rotor
en los motores hace la velocidad es
controlada mediante la variación de la
frecuencia lo cual es comúnmente hecho
con un variador de frecuencia
