Single-phase motor, refers to by220VAn asynchronous motor that operates on a single-phase AC power supply. The selection of capacitance capacity of single-phase capacitor starting motor is determined according to the design data of winding, and the formation of circular rotating magnetic field is the basic principle. The following simple and Senli motor Xiaobian together to understand.
Electrolytic capacitorSingle-phase machineThe starting application is more common, but also mainly based on its specific advantages: the capacitance per unit volume of electrolytic capacitors is very large, and can be dozens to hundreds of times larger than other types of capacitors.
The rated capacity of this type of capacitor can be very large; The price of electrolytic capacitors has an overwhelming advantage over other types, because the components of electrolytic capacitors are ordinary industrial materials.
Electrolytic capacitors are divided into polar electrolytic capacitors and non-polar electrolytic capacitors. We can simply understand that polar capacitors are capacitors that can only be used in one voltage direction, while non-polar capacitors can meet the voltage in both directions.Ac single-phase machineAlso can only use non-polar capacitors.
