Why is an AC motor more popular than a direct current motor? System description, thank you.
Also in accordance with the phase asynchronous AC generator rotation, (here is asynchronous: rotating magnetic field of asynchronous AC motor and AC Alternating Current AC motor drives the rotating magnetic field rotation, phase difference, so that is asynchronous).
When it comes to the DC to AC by rectifying and filtering can be compared to DC, DC motor and AC motor, DC motor, high cost, complex loss, ratio of AC motor high failure rate, high cost, low penetration rate, while the AC motor can be positive, but not DC motor. It is the alternating current AC generator produces alternating current AC motor drives the rotation, so
When it comes to AC motor, said first alternating current, alternating current is often used in our daily life, low price, wide use, AC Alternating Current AC motor can adapt to any electrical equipment, is no exception, the reason is the three-phase alternating current of each phase is 120 degrees, 360 degrees, this is just a three-phase AC motor is welcome to good, so the AC motor will be popularized
The reason of AC motor is common and convenient power supply: power generator and transformer, transmission and distribution in the form of communication, AC power supply, the utility grid can be directly used for AC motor is simple and convenient; DC motor to be alternating to direct before use, trouble.2, AC motor especially the induction motor, has the advantages of simple structure, easy manufacture, convenient installation, reliable use, low cost, high efficiency; and the DC motor is complicated in structure, manufacture and installation of trouble, use is not reliable, high cost, low efficiency.
