As an open-loop control system, stepping motor has essential connection with modern digital control technology. In the current domestic digital control system, stepping motor is widely used. With the emergence of all digital AC servo system, AC servo motor is more and more used in digital control system. In order to adapt to the development trend of digital control, stepping motor or full digital AC servo motor is mostly used as the executive motor in motion control system. Although they are similar in control mode (pulse train and direction signal), they are quite different in performance and application. This paper compares the performance of the two.

Presumably everyone is also curious about the cooling effect of the air conditioner. In fact, all this is the credit of the compressor. The principle is that the compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it t 器2 䀀 ᅵ皥 䖒皦즠Ʋ煔क़ 㲈Ʋ 䌁皦 ᮔDž༬皧煞क़Ѐ 呄ᠾ鹨់༹皧 ࠄ 00령ꐱ댁珵뛐珵Љ 䕄ྦ 뤂ᐱ뚜珵 ᴴᏩ呄ᠾ퍘ᒥ 鹨់ᩄ ꋔྦ 瑉浥 巠皱㙲皦抐皱 巠皱 ੨皦柘皱 ᅵ皥 ب 巠皱㙲皦忈皱 ੨皦柘皱 즠Ʋǜ 勁皦즠Ʋب ǜ V / 펔B䌁皦 ᮔDž '鱤džၜ먢䇨珵呈ᠾ뤂ᐱ ⿇⬿먲僧ᐱ㥲ᐲ�僬㣢ᐲ ᠾ 랖僧Ѵ 識 �僬㣢ᐲ 臆S㥲ᐲ ᬄğ
