Abstract: Aiming poor precision and flexibility of the analog speed control method, a digital speed control scheme for the single-phase motor is proposed. Firstly, the principle of single-phase AC variable voltage speed control is introduced, the main circuit of the controller and the zero-crossing detection circuit are designed, and then the circuit simulation and parameter optimization are carried out. On that basis, an STM32-based variable voltage speed controller for the single-phase motor is built. The zero-crossing detection of supply voltage is accurate. The simulated and experimental results are shown to be in good agreement, verifying the reliability of the digital speed control method.
Key words : variable voltage speed control;single-phase asynchronous motor,;STM32,;TRIAC;digital control

單相異步電動機具有結(jié)構(gòu)簡單,、價格低,、性能良好、操作方便等特點,,被廣泛地應(yīng)用于工業(yè),、農(nóng)業(yè)和日常生活中[1-2]。目前異步電機的調(diào)速方法主要采用變頻調(diào)速和調(diào)壓調(diào)速兩種[3],,其中調(diào)壓調(diào)速線路簡單,、成本低廉、沒有諧波干擾現(xiàn)象,,在異步電動機調(diào)速控制方面已逐步體現(xiàn)出優(yōu)勢,。另外,為了實現(xiàn)電動機的調(diào)速控制,,與常規(guī)模擬調(diào)速方法相比較,,數(shù)字控制具有控制精度高、柔性化和模塊化程度高等特點,,對外部環(huán)境復(fù)雜,、對產(chǎn)品性能要求高的場景(如風(fēng)機的通風(fēng)、排塵和冷卻)適用性更好[4-5],。
本文提出了一種基于STM32F103控制的單相異步電動機的調(diào)壓調(diào)速方法,,通過控制雙向晶閘管(TRIAC)導(dǎo)通時間實現(xiàn)調(diào)壓調(diào)速。設(shè)計了相應(yīng)的主電路和控制電路,,通過仿真和實驗分析優(yōu)化電路參數(shù),,從而實現(xiàn)風(fēng)機系統(tǒng)調(diào)壓調(diào)速目的。
