In the construction field, single-phase motors are widely used in elevators, fans, water pumps, etc. Single-phase motors can be directly connected to the home 220V power supply, which is easy to use and relatively cheap.
Single-phase motors are widely used in home appliances, office equipment, agriculture, construction and other fields due to their small size, low power and easy use. Compared with three-phase motors, single-phase motors have lower costs, but may not be energy-efficient in some occasions and their service life is also shortened. In general, the application field of single-phase motors will continue to expand and become one of the indispensable equipment in all walks of life.
