Why are alternators more common?
Alternators are more common than DC generators, mainly because alternators are more efficient in the transmission process. Since the AC signal has less signal attenuation during long-distance transmission, it can maintain a higher voltage over a long distance. In contrast, a direct-current signal has a large signal attenuation during power transmission, and thus it is difficult to perform power transmission over a long distance.
AC motor (alternating-current motor) is mostly abbreviated as AC motor in English.
Where is the motor industry? High-speed direct drive motor is still the mainstream
As the "big heart" of mechanical movement, the motor appears in our living environment all the time, such as shopping malls, office buildings, hotels, schools, hospitals and other places are inseparable from the auxiliary operation of the motor. With the rapid development of industry, the matching of motors in all walks of life is particularly important, that is, high precision, miniaturization and low speed of motors are required.
