ZJSHUYI What is an AC drive?www.shuyitop.com; #inverter #ACdrive #freque...

In industrial applications, the speed control and torque control are not very demanding for general use of frequency converters, and in the occasions with strict position control requirements, the intelligent use of AC servo drives is used to achieve, and the response speed of the servo is much greater than Frequency conversion, some occasions that require high speed accuracy and response are also controlled by AC servo drives. That is to say, almost all occasions that can be controlled by frequency conversion can be replaced by AC servo drives. AC servo drives and inverters can be said to be a pair of brothers, both of which are drives of AC motors. According to the order of appearance, the inverter should be called the elder brother, and the AC servo drive should be called the younger brother. The frequency converter drives the frequency conversion motor, and also drives the ordinary AC motor. The main function is to adjust the speed of the motor. The AC servo driver drives the AC servo motor, and its main feature is precise and fast positioning and tracking, and precise position control. As one of the supporting technologies of modern industrial automation and motion control, AC servo drives are widely used in machine tools, printing equipment, packaging equipment, textile equipment, rubber and plastics due to their precise high-speed control, wide speed regulation range, high dynamic characteristics and high efficiency. Equipment, electronic semiconductors, wind power/solar energy and other new energy, as well as robots, automated production lines and other fields. However, the AC servo drive has developed frequency conversion technology, and the AC servo drive has learned from and applied the frequency conversion technology. Based on the servo control of the DC motor, it is realized by imitating the control method of the DC motor through the frequency conversion PWM method, that is to say, the AC servo motor is realized. There must be this part of frequency conversion. Like the inverter, the power frequency alternating current is first rectified into direct current, and then converted into alternating current with adjustable frequency through the carrier frequency and PWM adjustment through various transistors (IGBT, IGCT, etc.) that can control the gate. Cosine of pulsating electricity. Are AC Servo Drives Replacing Inverters? , there are two key factors in whether it can be replaced in the end, one is price and the other is power. If one day in the future, the servo brother "condescends" in price, will the inverter brother become more and more "lonely"? If the inverter brother makes technological breakthroughs, will it appear that there will no longer be a brother and a brother, and will become a real A family? The development of technology is as fast as a flash, always beyond our imagination, looking forward to a future with rapid technological progress. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #inverter #forfrequencydrive #ACvfd #frequencyinverter #ACdrive #motorinverter #singlephasemotorvfddrives #variablefrequencydriver #frequencyconverter
