It only has an alternating voltage
In the domestic sphere, electric motors have a wide application, so it is necessary that they can work in single-phase networks.
Single-phase motors are very similar to three-phase motors, with the disadvantage that their performance and power factor are lower and, whenever conditions allow, three-phase are used.
The most used are: Motors with IE 2 efficiency Degree of protection IP 55 three-phase motors 0.5 hp - 40 HP single-phase motors 1 hp - 10 hp
Single-phase motor with starting auxiliary winding.
Loop motor shorted.
